Python/Jupyter developer in Boston. I build data tools and I start by talking to the people who'll use them, because code that doesn't get adopted is wasted work. My main thing is Buckaroo (github.com/paddymul/buckaroo, ~680 stars), an open-source data table for Jupyter over Pandas/Polars. I built both the data layer and the React frontend. Looking for a team building data tooling (as a product or in house).
Hi, I'm Jonathan. I’m currently doing DevOps work for an open source project, operate a small web hosting company, and working as an accounting assistant for a local firm. My skillset is focused on the System Administration/DevOps side, with a bit of general dev experience primarily with Python. I have a PhD in Physics where my research focus was computational biophysics. On the side I also host my own infrastructure as a hobby, from the hardware to the nameservers and everything in between.
Having worked at startups before, I’m comfortable wearing many hats (and enjoy the variety).
Backend/platform engineer with 6 YOE. I started in DevOps consulting, building automation, CI/CD, and Terraform/Packer workflows for Fortune 500 clients, then moved into backend engineering on a healthcare claims/payments platform.

SEEKING WORK | Data scientist consultant | Canada/Remote Worldwide
Most of what people call "data science" is now doable with an LLM and a weekend. I focus on the messy, ambiguous, regulation-heavy gnarly problems where nobody is sure what the right question is.
What I've done:
- Saved a German automaker from lemon law recalls. ($20M+ exposure avoided)
- Real-time emissions detection for industrial smokestacks. ($75K fines per incident prevented)
- Revenue optimization and persona identification for debt collections (15-20% net revenue lift)
- LLM-based legal document extraction, reducing due diligence turnaround from 3 days to 30 minutes
- Built vessel piracy risk engine that informed naval escort deployment, contributing to fewer hijackings
Hi, I’m Fabrizio Milo, a senior AI/ML engineer, large-scale systems architect, and former technical co-founder. I’ve spent my career building production AI, ML infrastructure, and high-scale backend systems across startups and growth-stage companies.
Most recently, I’ve been building AI platforms for LLM training and fine-tuning, RAG databases, local and remote LLM inference, semantic retrieval, and agentic orchestration for business intelligence and code generation. I’ve also contributed to open source ML projects including GPT-Neo, TensorFlow and published research on synthetic data from LLMs.
Previously, I was VP of Technology at ZELIG, where I led the virtual try-on AI research roadmap and managed a cross-functional team building ML/3D systems for fashion retail. Before that, I was Head of Machine Learning Engineering at Recurrency, where I hired and led a 6-person ML/platform team and shipped demand forecasting, dynamic pricing, and recommendation systems on AWS/Snowflake/SageMaker. I also co-founded Passio, where I built the technical foundation for an on-device Nutrition-AI SDK with real-time computer vision inference.
Earlier in my career, I built scalable systems at TheRealReal and Scopely, optimized CUDA kernels at NVIDIA, and worked on real-time market-data and high-performance systems. I’m strongest where AI research, production engineering, and startup execution meet: taking ambiguous technical/product goals and turning them into shipped systems, teams, and infrastructure.
I can architect and build anything you need given enough compute and time.

24 years in infrastructure, currently Lead Platform Engineer at a security AI startup where I built the platform team from scratch (0 to 5 engineers) and architected multi-tenant Kubernetes infrastructure across 40+ clusters with per-tenant KMS encryption and Argo-based progressive delivery.
Before that, spent nearly 6 years as Staff SRE at Iterable where most of my work centered on making infrastructure cheaper and more reliable. Replaced ELK with Quickwit for 65TB/day log ingestion (saved $1.2M/year), migrated Lambda pipelines to Vector ($60k/mo down to $8k/mo), and stood up
VictoriaMetrics to replace Datadog for 33M metrics ($30k/mo savings). I tend to find the project that saves the most money and then actually build it.
I write Go -- built Kubernetes operators for RabbitMQ, Redis, and Vector (open source: github.com/zcentric/vector-operator). Terraform is my IaC of choice and I've used it everywhere from a global Predix platform (Japan, EU regions) to scaling Kubernetes clusters from 10 to 300 nodes on spot
instances for satellite image processing at Urthecast.
I've managed teams at three companies (up to 6 engineers) and served as product owner for SRE groups, but I'm open to both IC and management roles at the Staff/Principal/Director level.
Looking for: DevOps, SRE, Platform Engineering, or Cloud Infrastructure roles. $200K+ total comp. Remote only, US-based.
I’m Naman, looking for GTM Engineering, Growth Engineering, GTM Systems, RevOps, Founder’s Associate, Sales Engineering, Product Manager or related roles at early stage startups.
I’ve spent the past few years working close to founders on GTM, partnerships, community, events, and early distribution. At Rally Tax (YCW23), I helped build outbound and partnership motions. At Koinz Capital, I helped source early stage startup dealflow across AI, healthtech, SaaS, consumer, fintech, student founder networks, and startup events.
Best fit: early stage teams that need someone who can build GTM systems, run outbound, clean data, automate workflows, talk to users, and move fast without much structure.
I build AI agent infrastructure. Most recently: Tracea (tracea.dev), an open-source observability platform for AI agent teams that patches the HTTP transport layer to trace LLM calls without any framework changes — no SDK wrappers, no code changes, just install and instrument. Also built ObservAgent (1000+ active users, open source).
Research side: co-authored a paper on failure-aware penetration testing - training LLMs to emit typed failure tokens so failure recognition becomes a structured recovery signal rather than an implicit state.
Prior: full-stack engineer shipping software to 50k+ users.
Looking for full-stack or AI/ML engineering roles at early-stage or growth-stage companies working on production AI systems - LLM integration, agent infrastructure, or observability. High ownership, real users, hard problems.
What I do: I build agentic systems and full-stack infrastructure — things that ship, observe themselves, and run autonomously.
Recent work:
- Founding contributor at NimbleBrain: designed the agentic loop and workflow engine that guides AI agents through building and publishing MCP server integrations end-to-end
- Co-created Vispyr: self-hosted observability platform on AWS with automated infra provisioning, OTel instrumentation, and a full Grafana telemetry stack

Hello, I'm Alex, backend engineer with 12+ years building distributed systems. Most recently I was at IBM QRadar. Before that, I worked at successful startups as early as the 3rd engineer on the team, so I'm comfortable building backend from scratch and owning new parts of a system. I'm now doing a part-time Georgia Tech MSCS focused on low-level and ML systems (CUDA, vLLM). Open to senior backend roles, and especially interested in LLM serving and systems-level work (C++).
I’m a senior engineer and software architect working with teams that are starting to strain under growth, complexity, or delivery pressure.
Over the last ~10 years I’ve been working with startups and established companies, primarily in roles where I take end-to-end technical responsibility: from system design through implementation and production operation, while remaining hands-on in delivery.
Recent work includes leading the architecture, implementation, and operational ownership of a distributed platform for venture capital workflows, as well as building and maintaining a production survey fulfillment system. Both engagements included mentoring and coordinating engineers alongside delivery. More details can be found at https://robinsiep.com.
I’m primarily available for contract work, but open to longer-term roles with the right fit.
I’m an ML Engineer with a software engineering background and an MS in EECS. My recent work has been around deep learning, computer vision, medical imaging and data workflows for real-world ML systems.
Before moving deeper into ML, I worked as a backend Software Engineer building payment processing systems with Java/Spring, REST APIs, and SQL databases.
I’m looking for ML Engineer, Applied ML Engineer, Computer Vision Engineer, Backend/ML Infrastructure Engineer, or Software Engineer roles. I’m especially interested in teams building practical ML systems, scalable inference/data pipelines, backend platforms, or applied AI products.
Hi, I'm Branko. I am looking for a part-time or contract position in a small team where I can wear multiple hats: building features (Frontend/Node/Laravel), handling support tickets, writing documentation, and improving SEO.
I have an engineering degree in Geodesy/GIS and 5+ years of customer support experience. I've developed products like a text analysis tool, a fishing logbook app, and an app for easing certain customer support tasks (links on website).
If you need someone who is just as comfortable handling support and documentation as they are writing code, I'd love to chat.
I'm looking for 20–30 hours per week of work in Linux administration and/or (web) application development. I'm good at solving problems in unconventional ways. I've developed several (web)applications - some of them quite complex - either on my own or as part of a small team. I have a strong moral compass.

I'm a systems programmer and I am happier the lower in the stack I am. The narrative of my career is one of going deeper into the infrastructure, deeper into the stuff that other people get to build on top of. I most recently spent a couple of years on the async Rust dataplane at Cloudflare, working on an L3/L4 software router. I write Rust by preference now, but I've shipped a lot of C and C++ down at the layer where you have to care about NUMA, syscalls, and where every packet goes.
Former graphic designer turned software developer with 10+ years of professional experience. Most recently, I've been building highly dynamic frontends with React + utility apps in Go. Prior to that, I was re-writing legacy desktop applications as web based with Vue + Go + Postgres. I'm comfortable working across the stack, and adapting to new (or old!) technologies.
Currently working on a VST plugin in C++, and I have explored a number of other areas over the years. Such as: mobile, games, graphics programming, and embedded systems.
While most of my work has been web focused, I'm open to working in other areas. Check out my website, sectionfourteen.com, for more detailed info.
MS CS (AI/ML) — Northwestern '24 | Currently: AI/ML Engineer

Comfortable across the full stack from model training to serverless cloud deployment.
Open to ML Engineering, Applied AI, AI Infrastructure, Software Engineering or Data Scientist roles.
I'm currently doing a lot of open social Web stuff at https://www.olamaelcu.net/ but it's all free stuff and not (currently) paying. Would like to still keep lights on!
Full-stack engineer with 5+ years of experience in decentralized and distributed systems and the Ethereum ecosystem. Looking for a full-stack or back-end engineering role in distributed systems, preferably working with Go and TypeScript/JavaScript although I'm open to learning about new languages and platforms. Something open-source will be a big plus.
I'm a full-stack product engineer with experience building end-to-end features for products across different technologies. I value fundamentals and I'm used to working with a diverse set of technologies and view frameworks as tools that can be learnt on the go. I’m comfortable with remote collaboration with international teams.
Embedded engineer (8 years). I work from PCB design to firmware, board bring-up, optimised bare-metal C, and front-end.
Latest thing: a 6-layer BGA STM32H7 board that runs Lua and JavaScript on the MCU, with a browser-based editor. The firmware also compiles to WebAssembly, so the editor doubles as a simulator. Before that, mostly avionics and motor control.
Looking for embedded/firmware work, hardware bring-up, anything STM32 related.
I'm a Product Engineer and a creative based in London. I’ve built full-stack applications across web, mobile, blockchain and embedded platforms. My client-side work includes React, Electron, Roku’s Scenegraph, and native iOS development with Swift and SwiftUI, always with a strong focus on UX and design-first thinking. On the service-side, I’ve worked with traditional service hosting, containers, and serverless, including (but not limited to) AWS, GCP, Cloudflare, Workers, CloudFormation, SAM CLI, nodejs, bunjs, MySQL, Postgres, NoSQL, grpc, Redis, Docker, nginx, and a few legacy tools best left unnamed (yes, including CodeIgniter and ftp).
I’ve also developed developer tools like CLIs and SDKs, primarily Typescript/JavaScript land, and have written code in systems languages such as Rust and Zig.
I care about clean code, great UX, developer experience, documentation, rapid iteration and automating workflows with CI/CD (GitHub Actions, Bash scripts, etc).
Also familiar with modern development practices by leveraging coding agents, such as pi, opencode, claude and LLM, including kimi over fireworks inference.
Just about done finishing up a CS master's degree, and looking for opportunities starting in the late summer or fall. My background is in programming language theory (particularly logic/relational programming), so would be very happy to work with functional languages, compilers, automated reasoning, and/or formal verification. I also have a background in music (I'm a published composer!) so particularly interested in audio/music-related stuff as well. Open both to software enginering roles and research positions (anyone looking for new PhD/doctoral students?) I've also done full-stack work across databases/cloud infrastructure/web APIs/frontends, and independently released a commercial music production plugin (Pivotuner, more info on my website).

Backend operator with experience in enterprise systems, operations, and product execution. Most of my work has been in ambiguous, high responsibility environments requiring technical depth, judgment, systems thinking, and coordination across technical and business domains. MSc Quantitative Economics.
Recently:
• Built and deployed a production RAG platform (Python, FastAPI, React, Qdrant), including ingestion pipelines, hybrid retrieval, ranking/debugging workflows, and tooling to improve retrieval quality, reliability, and system stability as datasets scaled.
Previously:
• 10+ years building and owning backend, data and reporting systems across ERP, BI, integrations
• Responsible for reliability and audit integrity of business critical systems in multinational operations
• Led technical delivery teams across engineering, finance, IT
• End-to-end delivery in independent product/founder environments
Primarily interested in short to mid-term contract or project based engagements. Open to longer term collaboration where there is strong mutual fit.
15 years as a full-stack AI engineer, including onsite engineering and team leadership for US enterprises ADP and Time Warner Cable. I ship agentic AI products in 2 to 3 weeks, not months.
What I build:
-> Multi-agent systems with LangGraph, CrewAI, OpenAI Agents SDK, and AutoGen. Tool use, handoffs, planning loops, and guardrails that hold up past the demo.
-> Production RAG pipelines with pgvector, reranking, and evaluation. Not just a notebook.
-> AI-integrated full-stack apps on Next.js, Supabase, and Stripe. From MVP to scale.
Best fit: founders building agentic AI products who need senior engineering judgment, not just code. I have led and mentored engineering teams, so I can own architecture decisions and bring the rest of your team up to speed.
Open to fixed-bid projects, ongoing contract work, or fractional technical lead engagements. Competitive rates for the quality delivered.
I've mostly been a first or founding engineer, owning and evolving end-to-end systems in fast-moving environments. I focus on high-throughput pipelines, messaging platforms, media processing, recommendation engines, and real-time infrastructure.
I also build real-time dashboards and browser-based tooling to observe, debug, and control these distributed systems, using local-first storage and media processing as well as real-time communication workflows. I design systems that remain understandable and resilient under load, retries, and partial failures.
Recent work:
- Built a messaging system delivering millions of emails and push notifications in minutes (retries, deliverability, observability)
- Deployed real-time pipelines and recommendation systems for tens of millions of users
- Launched a browser-based video editing and encoding platform using FFmpeg, Supabase, and AWS serverless
- Scaled event ingestion 100x to power analytics, experimentation, and targeting
I do my best work in small, product-focused teams where engineers stay close to production, communicate early about risks and tradeoffs, and work directly with customers to solve concrete problems.
Currently interested in full-time, part-time, or contract:
- Forward deployed engineering
- Founding or early engineering
- Platform and systems engineering
- Data engineering
Pragmatic about LLMs: effective for exploration, debugging, documentation, and tightly scoped implementation work when paired with strong engineering judgment and rigid testing.
Hey, I'm Arpad. I have a background in signal processing, deep learning (mainly computer vision), and embedded systems. I have 5+ years of research experience and end-to-end edge AI development. My strong suite comes in GPU + embedded development, optimization, and architecture design.
Best fit: fast-moving teams, end-to-end ownership, collaborative.

Senior Ruby on Rails developer, 11+ years across fintech, SaaS, e-commerce, and startups. Open to full-time remote or contract. What I'm best at:
Performance work on existing codebases. Once optimized a set of Rails API endpoints from 90-120s down to 1-2s — measuring first, raw SQL where ActiveRecord produced bad queries, indexing, restructuring background jobs. External API integrations (5+ over my career: Google Maps, Chargebee, WhatsApp via 360dialog, SDB Groep, AFAS). Comfortable with the messy parts — retries, idempotency, webhook ordering, partial failures. Working with legacy and tests-nobody-touches. Reading before writing, refactoring without breaking things. As Tech Lead at clevergig (Dutch SaaS) for 3 years, I set up code review, bug tracking, and ownership processes for a long-lived codebase.
For fun: building a Rails app + ESP32 device that tracks power outages at my home — the device pings the API every minute, the Rails side aggregates into hours-with-power vs. without. Started during the post-2022 outages in Kyiv and kept evolving — a good way to keep Rails fresh and combine backend with a bit of hardware.
Heya, I am frontend developer with 4+ years of experience working with React, Next.js and much more. I have written some blogs about things I built.
I am always up for learning new things and applying it, So if you are looking for someone who can be in your niche tech or something challenging,Then I am your guy.
Other than that, I love movies and books, mainly stories, world building, fantasy, so if you are working on anything like that, I am hugely interested.
Native application development for iOS, Android, Mac and Windows with over a decade of experience. Creating and/or integrating APIs/SDKs. TV/Video applications on all platforms (Apple, Android, Amazon, Roku.) Extensive experience building products and platforms from the ground up.
Senior software engineer, 20+ years building pipelines that turn real-world events into decision-useful information — industrial control and IoT (manufacturing, ~50-person autonomous teams), large-scale product-data aggregation (5-7M products, multi-source), regulatory documents (1.5M+ documents, ~4,000 sources).
Same pattern across domains: acquire from whatever sensing the world provides, curate, structure for processing, find correlations across heterogeneous sources.
Working with neural nets through multiple AI cycles (neuroevolution and genetic programming, deep learning, now LLMs) — perspective on what survives the hype.
Currently: regulatory forecasting for Polish law, ~30K-document scale, autonomous overnight sweeps. The hard problems are turning messy real-world streams into decision-ready information, at scale, under uncertainty.
I write about where AI coding agents actually work and where they quietly fail — walat.eu/series/ai-agents-in-practice/
Best fit when the work is engineering-shaped — application/data rather than infra/SRE/Kubernetes-heavy — and the schedule overlaps EU hours.
Comfortable as autonomous IC or small-team tech lead. Domains where messy real-world data meets non-trivial reasoning are where I'm sharpest — industrial, regulatory, scientific.
Software Developer with experience in Full Stack, Front-End, and Data Analysis. I develop in my free time and love creating meaningful software. I also develop games as a hobby. Please feel free to check out my LinkedIn, GitHub, and Newgrounds game, Mo' Rockets. :)
I build production AI systems — agent runtimes, LLM tooling, RAG — and the backends behind them, in Rust where reliability matters and Python/TypeScript to move fast with a team. Most recently I wrote the core of Ward in Rust myself (agent runtime, analytics layer, multi-tenant audit/security model); it runs in a paid POC against a $400M, 850-store retailer's live SAP data. Before that I co-founded a YC W24 startup, took a Meta Marketplace product from zero to ~10k monthly transactions, and re-platformed a failing commerce backend to Rust that cut its AWS bill ~70%. ~10 years across fintech, healthtech, and commerce.
25-year design-led product builder. Apple Design Award winner (2003, Tubatomic, commercial work for Warner Bros, HGTV, Turner). Ran Hoff & Pepper hot sauce 10 years (1M bottles, 5,000 retail doors, Hot Ones S16) before winding it down. Past 12 months: shipped Steadcast (native macOS podcast app, live in the Mac App Store at https://steadcast.co) and its Knowledge Engine: queue-based Whisper on self-hosted RTX 3060 (17.9× realtime), 410-rule editorial voice guide, Promptfoo eval gates blocking bad output before it persists, mixture-of-models routing (Llama 3.3 for structured extraction, GLM-5.1 for prose), cost ceilings, monitoring, soak windows.
Best fit: AI features that need to actually work in production. Non-technical founders burned by agencies. CPG/DTC operators who want an operator-builder, not a consultant. Fractional Product Lead engagements.

I'm a Full-Stack Developer, Web Designer and Image Editor with over 25 years of professional experience. Problem-solver and avid learner, I'm used to working with small and large teams across enterprise, government and third sector. I take deadlines and delivery commitments very seriously.
I’ve been working as a full stack developer with a focus on education for more than 13 years. Increasingly my focus has shifted from just the technology towards the product. I believe that technology should empower people and create a healthy society that we all want to be a part off. This requires deliberate effort and attention to achieve and maintain. I'm looking to build a product I believe in, for profit, while learning new things and forming meaningful professional relationships.
I'm looking for monthly/yearly "no-strings" sponsors, not employment, if any individuals, companies (or bitcoin millionaires) would like to help a long-time OpenBSD slacker, unslack, I'd really like to focus more of my time on open source development (and advocacy), rather than making rent. Feel free to contact me.
Two-time founding engineer. Currently the first engineering hire at N86, building the platform 0→1 with the founding team. Previously founding engineer / frontend lead at mfg.parts, where I built a real-time collaborative 3D CAD viewer (React + Autodesk Platform Services + PubSub) and ran user research with 110+ users across 40+ companies. Also did a full-stack stint at Acadium, shipping an internal sales dashboard that cut response time 40%+.
I'm a frontend-heavy full-stack engineer who closes the design-to-code loop solo. Comfortable with ambiguity, real-time collaborative interfaces, and agentic workflows as a daily working mode.
If you want an eager engineer who thrives in early-stage chaos, reach out! I'm also open to contributing on a contract, internship, or volunteer basis for young startups — in exchange for experience, equity, or a mix. Happy to chat.
Senior Cloud Infrastructure Engineer with 6+ years across backend, AWS infrastructure, and FinOps. Realized 30-40% AWS cost reduction. Translates executive intent into infrastructure decisions and surfaces platform constraints back to the C-suite. Sole inventor of a 0-RTT VPN handshake (USPTO pending). Currently expanding into Cloud Security architecture.
Sole CI/CD owner for a major Japanese megabank's web platform at Deloitte (Next.js + Sitecore on AWS ECS, GitLab CI/CD). Built GCP Dataflow ETL pipelines with Java and Apache Beam for a connected-vehicle program. Built AI-augmented infrastructure operations on Claude Code, delivering one engineer-year of capacity in production ops. DDoS mitigation 3x including SYN-flood, root-cause analysis through WAF deployment.
Looking for: ~60-80h / month additional engagement alongside my current role, async-friendly. SRE / DevOps / Platform Engineer / Security Engineer / Technical Advisor. Rate negotiable by scope and engagement length; reach out via email.
For one year I reverse-engineered the major education platforms — Google Docs, Microsoft Office, Nearpod, Kahoot, ect. — so that AI agents can drive them on a teacher's behalf and automate classroom workflows. The work runs in over 10,000 classrooms today.
Building agents against production code you don't control is harder than it sounds. The code is mangled, so first you have to understand how the app was built and then take it apart from the outside. It's reverse engineering, but it depends on knowing how to build the thing in the first place.
The role came with monthly compliance and security training centered on FERPA, so I'm fluent in handling student data responsibly. That's not new ground for me. I spent five years building on Drupal, which the most prestigious learning institutions still run today, and version control and access control were the hard part of every project. Student data is the same problem.
I've been building browser agents and browser automation since 2018, well before it was a category. That's paired with 13 years of building dynamic, data-heavy UIs for web and mobile.
I've also built admin dashboards for a custom legal document management system. And a CRM for email marketing, with a drag-and-drop interface for designing and branding email templates for social campaigns. I've taken several companies from 0 to 1, as a consultant and as a full-time employee, across fintech, streaming, real estate, education, marketing, and media. I've worked at a 130-person AI company and on a 7-person team where I wore every hat. I do my best work on small, fast-moving teams.
Availability: Fractional / contract / fixed-scope, not seeking FTE

Strongest in TypeScript/React/Node.js and pragmatic product/system architecture, with ownership across product, backend, frontend and infrastructure. I also created SignalDB, an open-source local-first database with 600+ GitHub stars.
I'm happy at my current job with the Hakai Institute, but programs are shrinking and it's looking like days are numbered. I'd love to connect with people doing interesting things.
Lately I'm in the spaces between data science and engineering reliable, high-performance, resilient, yet highly-usable tools for scientists and other developers, across the stack. It's a lot of fun.
Some recent projects:
- Performance tuning and infrastructure cost-reductions on https://oceanconnect.ca. It's faster and cheaper to run than ever. Costs are essentially cut in half, and performance across hot paths, on average, is about 30% better. There's now comprehensive observability across the stack, making it so we can rapidly diagnose issues with complex model processing pipelines and data acquisition systems. On top of that, the error rate has dropped dramatically despite increased visibility into what's going wrong (a lot of issues were silently swallowed by OOM culling in Lambda, for example)
- Developing a low-cost solution to autonomously regulate temperatures in 40 saltwater tanks in a remote lab, using equipment which doesn't support remote controls. Using digital potentiometers inserted into each temperature controller, the system spoofs the tank's temperature to trigger heating or cooling, then observes until the correct temperature is reached. It uses several dissimilar redundancies, including a dead man's switch, to ensure there can't be run-away heating or cooling loops. The cost for new hardware with remote control capability came in close to $100K, but this solution (along with supporting software for designing temperature profile time series, monitoring tanks, and viewing historical data) is under $15K, yet required much of the same supporting software work. It's fully compatible with future hardware supporting direct remote control, as well; we'd only need to remove the temperature-spoofing loop and send set points to the units instead.
- A library for analyzing biodiversity datasets, inferring semantics about their data, and then creating a declarative configuration which can be used to transform the data to Darwin Core and validate it. It has a core library that can be used in any kind of client, like a CLI, web API, or a GUI. The declarative configuration makes it so datasets can be worked on in GitHub, then the CLI can run in a workflow to ensure it's still valid as it changes and grows. It uses DuckDB to make assertions about primitive types and data/relational integrity, then uses the application layer to make semantic assertions according to the specification's requirements. The entire workflow is highly supportive to scientists, explaining any issues with the data in very plain terms from start to finish. This has made it so scientists can make old records conform to the standard and have it ready for publishing far faster and with higher confidence than ever. At the same time, it also serves the purpose of helping scientists understand a large, complex standard one field at a time as they work through issues, rather than forcing them to tackle the entire standard from the outset. Ideally, this will lead to them working with the standard earlier and more often, with better knowledge and intuition for how to do so. It's built using Deno, Effect, Qwen 3.5 (for initial semantic inference passes), and DuckDB.
I'm also interested in LLM harness development and creating more deterministic agents with safety and behaviour guarantees.
My work experience is diverse, ranging from SaaS to science to a bit of firmware and robots. I'm interested in just about anything so long as it's genuinely useful, challenging, and the team is excited.
- Corporate Automation & AI Workflows: Reducing operational overhead through n8n workflow automation, custom bot development, and Model Context Protocol (MCP) multi-agent systems.
- Enterprise Backend Systems: Engineering high-performance, secure, and scalable backend services using Go, Rust, C#, or Python.
Available for fractional, short-term, or long-term remote contracts. Let's discuss how I can help streamline your infrastructure or build your next decentralized solution.
About me: I’m a versatile Full Stack Engineer with 8+ years of experience building AI driven applications and scalable software systems.

Willing to Relocate: No
Technologies: Rust, systems-level development, database internals, embedded, C++
Summary: 25ish-years-experience systems software engineer. 10 years at Google. "Systems" level programmer, embedded systems, data structures, database internals, mostly in Rust. Plenty of open source experience. Looking for freelance, greenfield and/or interesting projects. Recent work all in Rust.
I’m a senior generalist engineer with founding-style ownership. I like building systems end-to-end: protocol and product code, backend platforms, infrastructure, internal tools, and product-facing surfaces. Several times I was either an initial or an early hire in small and large-scale projects and products.
For the last two years, I was a founding engineer at Load Network, an early-stage L1 EVM chain with Arweave-based data settlement. I worked across the stack: developed protocol-level abstractions, consensus and execution clients, bootstrapped infrastructure, DevOps, and smart-contract prototypes. I also built private AI agent harnesses, ran multi-agent tests, and used LLMs for spec review and cross-client protocol design research and data gathering.
Before that, I spent six years in gamedev building backend platforms for massive-scale games at Strikerz/UFL (uflgame.com) and Vizor Games. I was an early hire, working directly with the CTO to build the infrastructure and design the system from the ground up. I engineered microservices for matchmaking, game economy/payments, quests, auth, moderation, and data pipelines (Kafka, Postgres, ClickHouse). I also managed Kubernetes, observability, internal admin tooling in Python/JS, and took part in high-stakes production launches.
I built my engineering foundation in enterprise Business Intelligence and Data Architecture. I shipped large-scale data warehouses (OLAP) for global companies (pharma, logistics), writing heavily optimized Oracle PL/SQL and T-SQL.
Open source: Merged contributions to the Ethereum ecosystem, including the Reth client in Rust, Flashbots SUAVE, and Alloy.
These days, I'm spending more time on product-facing surfaces (React, Rails), exploring Zig, and using LLMs for the right dose of entropy and speed.
Looking for: founding engineer, senior/staff software engineer, full-stack or backend roles where broad ownership and technical depth matter.
I am building react native apps for marketplaces. Happy to help with your marketplace or work as a subcontractor for established agencies. I am a senior frontend dev with 6 years of experience.
We can structure a deal in a way that gives you a guarantee of a job well done, so that the partnership is risk-free for you.

Hi, I’m Fabrizio Milo, a senior AI/ML engineer, large-scale systems architect, and former technical co-founder. I’ve spent my career building production AI, ML infrastructure, and high-scale backend systems across startups and growth-stage companies.
Most recently, I’ve been building AI platforms for LLM training and fine-tuning, RAG databases, local and remote LLM inference, semantic retrieval, and agentic orchestration for business intelligence and code generation. I’ve also contributed to open source ML projects including GPT-Neo, TensorFlow and published research on synthetic data from LLMs.
Previously, I was VP of Technology at ZELIG, where I led the virtual try-on AI research roadmap and managed a cross-functional team building ML/3D systems for fashion retail. Before that, I was Head of Machine Learning Engineering at Recurrency, where I hired and led a 6-person ML/platform team and shipped demand forecasting, dynamic pricing, and recommendation systems on AWS/Snowflake/SageMaker. I also co-founded Passio, where I built the technical foundation for an on-device Nutrition-AI SDK with real-time computer vision inference.
Earlier in my career, I built scalable systems at TheRealReal and Scopely, optimized CUDA kernels at NVIDIA, and worked on real-time market-data and high-performance systems. I’m strongest where AI research, production engineering, and startup execution meet: taking ambiguous technical/product goals and turning them into shipped systems, teams, and infrastructure.
I can architect and build anything you need given enough compute and time.

24 years in infrastructure, currently Lead Platform Engineer at a security AI startup where I built the platform team from scratch (0 to 5 engineers) and architected multi-tenant Kubernetes infrastructure across 40+ clusters with per-tenant KMS encryption and Argo-based progressive delivery.
Before that, spent nearly 6 years as Staff SRE at Iterable where most of my work centered on making infrastructure cheaper and more reliable. Replaced ELK with Quickwit for 65TB/day log ingestion (saved $1.2M/year), migrated Lambda pipelines to Vector ($60k/mo down to $8k/mo), and stood up VictoriaMetrics to replace Datadog for 33M metrics ($30k/mo savings). I tend to find the project that saves the most money and then actually build it.
I write Go -- built Kubernetes operators for RabbitMQ, Redis, and Vector (open source: github.com/zcentric/vector-operator). Terraform is my IaC of choice and I've used it everywhere from a global Predix platform (Japan, EU regions) to scaling Kubernetes clusters from 10 to 300 nodes on spot instances for satellite image processing at Urthecast.

I build AI agent infrastructure. Most recently: Tracea (tracea.dev), an open-source observability platform for AI agent teams that patches the HTTP transport layer to trace LLM calls without any framework changes — no SDK wrappers, no code changes, just install and instrument. Also built ObservAgent (1000+ active users, open source).
Research side: co-authored a paper on failure-aware penetration testing - training LLMs to emit typed failure tokens so failure recognition becomes a structured recovery signal rather than an implicit state.
Prior: full-stack engineer shipping software to 50k+ users.

I recently worked as a Founding Engineer at BuilderBase, where I owned core parts of the codebase, engineering processes and product architecture from pre-seed through a €500K+ funding round. Before that, I worked at a US fintech (SixPoint Capital) contributing to AI-driven underwriting workflows, modular SaaS architecture, scalable APIs and agentic systems for private credit and structured finance. I also bring strong experience working in fast-growing startup environments and I am a founder myself, which gave me a broader product vision and direct experience in product decision making.
I have a graduation in Software Engineering area and I'm currently pursuing an MBA in Big Data. I'm also Certified Oracle AI Foundations Associate, JavaScript/TypeScript Platform Developer and on track for the AWS Solutions Architect - Associate.
I am currently looking for a full time remote role where I can keep working with modern TypeScript, Python backend APIs, scalable SaaS architecture and AI/ML integrations. True team player and committed to delivering results from the very first days. 0-1 specialist, high product vision and high ownership + clean communication working-style.
I'm a systems programmer and I am happier the lower in the stack I am. The narrative of my career is one of going deeper into the infrastructure, deeper into the stuff that other people get to build on top of. I most recently spent a couple of years on the async Rust dataplane at Cloudflare, working on an L3/L4 software router. I write Rust by preference now, but I've shipped a lot of C and C++ down at the layer where you have to care about NUMA, syscalls, and where every packet goes.

Former graphic designer turned software developer with 10+ years of professional experience. Most recently, I've been building highly dynamic frontends with React + utility apps in Go. Prior to that, I was re-writing legacy desktop applications as web based with Vue + Go + Postgres. I'm comfortable working across the stack, and adapting to new (or old!) technologies.
Currently working on a VST plugin in C++, and I have explored a number of other areas over the years. Such as: mobile, games, graphics programming, and embedded systems.
While most of my work has been web focused, I'm open to working in other areas. Check out my website, sectionfourteen.com, for more detailed info.

Embedded engineer (8 years). I work from PCB design to firmware, board bring-up, optimised bare-metal C, and front-end.
Latest thing: a 6-layer BGA STM32H7 board that runs Lua and JavaScript on the MCU, with a browser-based editor. The firmware also compiles to WebAssembly, so the editor doubles as a simulator. Before that, mostly avionics and motor control.
Looking for embedded/firmware work, hardware bring-up, anything STM32 related.

I'm a Product Engineer and a creative based in London. I’ve built full-stack applications across web, mobile, blockchain and embedded platforms. My client-side work includes React, Electron, Roku’s Scenegraph, and native iOS development with Swift and SwiftUI, always with a strong focus on UX and design-first thinking. On the service-side, I’ve worked with traditional service hosting, containers, and serverless, including (but not limited to) AWS, GCP, Cloudflare, Workers, CloudFormation, SAM CLI, nodejs, bunjs, MySQL, Postgres, NoSQL, grpc, Redis, Docker, nginx, and a few legacy tools best left unnamed (yes, including CodeIgniter and ftp).
I’ve also developed developer tools like CLIs and SDKs, primarily Typescript/JavaScript land, and have written code in systems languages such as Rust and Zig.
I care about clean code, great UX, developer experience, documentation, rapid iteration and automating workflows with CI/CD (GitHub Actions, Bash scripts, etc).

Just about done finishing up a CS master's degree, and looking for opportunities starting in the late summer or fall. My background is in programming language theory (particularly logic/relational programming), so would be very happy to work with functional languages, compilers, automated reasoning, and/or formal verification. I also have a background in music (I'm a published composer!) so particularly interested in audio/music-related stuff as well. Open both to software enginering roles and research positions (anyone looking for new PhD/doctoral students?) I've also done full-stack work across databases/cloud infrastructure/web APIs/frontends, and independently released a commercial music production plugin (Pivotuner, more info on my website).
I've been working on production-grade AWS deployments for over 10 years, so it's a bit hard to frame my experience/skill set. That being said, if you need help with almost anything AWS - architecture, infrastructure, performance, scale - feel free to reach out. Although versed in Well-Architected/multi-region/multi-account, I strive to supply the simplest solution for your particular scenario.

Email: govind@govindgupta.com
15 years as a full-stack AI engineer, including onsite engineering and team leadership for US enterprises ADP and Time Warner Cable. I ship agentic AI products in 2 to 3 weeks, not months.
What I build:
-> Multi-agent systems with LangGraph, CrewAI, OpenAI Agents SDK, and AutoGen. Tool use, handoffs, planning loops, and guardrails that hold up past the demo.
-> Production RAG pipelines with pgvector, reranking, and evaluation. Not just a notebook.
-> AI-integrated full-stack apps on Next.js, Supabase, and Stripe. From MVP to scale.
Best fit: founders building agentic AI products who need senior engineering judgment, not just code. I have led and mentored engineering teams, so I can own architecture decisions and bring the rest of your team up to speed.
Open to fixed-bid projects, ongoing contract work, or fractional technical lead engagements. Competitive rates for the quality delivered.

I've mostly been a first or founding engineer, owning and evolving end-to-end systems in fast-moving environments. I focus on high-throughput pipelines, messaging platforms, media processing, recommendation engines, and real-time infrastructure.
I also build real-time dashboards and browser-based tooling to observe, debug, and control these distributed systems, using local-first storage and media processing as well as real-time communication workflows. I design systems that remain understandable and resilient under load, retries, and partial failures.
Recent work:
- Built a messaging system delivering millions of emails and push notifications in minutes (retries, deliverability, observability)
- Deployed real-time pipelines and recommendation systems for tens of millions of users
- Launched a browser-based video editing and encoding platform using FFmpeg, Supabase, and AWS serverless
- Scaled event ingestion 100x to power analytics, experimentation, and targeting
I do my best work in small, product-focused teams where engineers stay close to production, communicate early about risks and tradeoffs, and work directly with customers to solve concrete problems.
Currently interested in full-time, part-time, or contract:
- Forward deployed engineering
- Founding or early engineering
- Platform and systems engineering
- Data engineering
Pragmatic about LLMs: effective for exploration, debugging, documentation, and tightly scoped implementation work when paired with strong engineering judgment and rigid testing.

Senior Ruby on Rails developer, 11+ years across fintech, SaaS, e-commerce, and startups. Open to full-time remote or contract. What I'm best at: Performance work on existing codebases. Once optimized a set of Rails API endpoints from 90-120s down to 1-2s — measuring first, raw SQL where ActiveRecord produced bad queries, indexing, restructuring background jobs. External API integrations (5+ over my career: Google Maps, Chargebee, WhatsApp via 360dialog, SDB Groep, AFAS). Comfortable with the messy parts — retries, idempotency, webhook ordering, partial failures. Working with legacy and tests-nobody-touches. Reading before writing, refactoring without breaking things. As Tech Lead at clevergig (Dutch SaaS) for 3 years, I set up code review, bug tracking, and ownership processes for a long-lived codebase.
Recent stops: FactCTO (fintech), Rail Europe, Fitjourney.ai, Kagi (Crystal backend), clevergig (Tech Lead).
For fun: building a Rails app + ESP32 device that tracks power outages at my home — the device pings the API every minute, the Rails side aggregates into hours-with-power vs. without. Started during the post-2022 outages in Kyiv and kept evolving — a good way to keep Rails fresh and combine backend with a bit of hardware.

Same pattern across domains: acquire from whatever sensing the world provides, curate, structure for processing, find correlations across heterogeneous sources.
Working with neural nets through multiple AI cycles (neuroevolution and genetic programming, deep learning, now LLMs) — perspective on what survives the hype.
Currently: regulatory forecasting for Polish law, ~30K-document scale, autonomous overnight sweeps. The hard problems are turning messy real-world streams into decision-ready information, at scale, under uncertainty.
I write about where AI coding agents actually work and where they quietly fail — walat.eu/series/ai-agents-in-practice/
Best fit when the work is engineering-shaped — application/data rather than infra/SRE/Kubernetes-heavy — and the schedule overlaps EU hours.
Comfortable as autonomous IC or small-team tech lead. Domains where messy real-world data meets non-trivial reasoning are where I'm sharpest — industrial, regulatory, scientific.

Résumé: https://chadbartley.github.io/chadbartley-site/
Email: chad@askotter.ai
I build production AI systems — agent runtimes, LLM tooling, RAG — and the backends behind them, in Rust where reliability matters and Python/TypeScript to move fast with a team. Most recently I wrote the core of Ward in Rust myself (agent runtime, analytics layer, multi-tenant audit/security model); it runs in a paid POC against a $400M, 850-store retailer's live SAP data. Before that I co-founded a YC W24 startup, took a Meta Marketplace product from zero to ~10k monthly transactions, and re-platformed a failing commerce backend to Rust that cut its AWS bill ~70%. ~10 years across fintech, healthtech, and commerce.

I’ve been working as a full stack developer with a focus on education for more than 13 years. Increasingly my focus has shifted from just the technology towards the product. I believe that technology should empower people and create a healthy society that we all want to be a part off. This requires deliberate effort and attention to achieve and maintain. I'm looking to build a product I believe in, for profit, while learning new things and forming meaningful professional relationships.
Trying something a bit different here again...
I'm looking for monthly/yearly "no-strings" sponsors, not employment, if any individuals, companies (or bitcoin millionaires) would like to help a long-time OpenBSD slacker, unslack, I'd really like to focus more of my time on open source development (and advocacy), rather than making rent.

For one year I reverse-engineered the major education platforms — Google Docs, Microsoft Office, Nearpod, Kahoot, ect. — so that AI agents can drive them on a teacher's behalf and automate classroom workflows. The work runs in over 10,000 classrooms today.
Building agents against production code you don't control is harder than it sounds. The code is mangled, so first you have to understand how the app was built and then take it apart from the outside. It's reverse engineering, but it depends on knowing how to build the thing in the first place.
The role came with monthly compliance and security training centered on FERPA, so I'm fluent in handling student data responsibly. That's not new ground for me. I spent five years building on Drupal, which the most prestigious learning institutions still run today, and version control and access control were the hard part of every project. Student data is the same problem.
I've been building browser agents and browser automation since 2018, well before it was a category. That's paired with 13 years of building dynamic, data-heavy UIs for web and mobile.
I've also built admin dashboards for a custom legal document management system. And a CRM for email marketing, with a drag-and-drop interface for designing and branding email templates for social campaigns. I've taken several companies from 0 to 1, as a consultant and as a full-time employee, across fintech, streaming, real estate, education, marketing, and media. I've worked at a 130-person AI company and on a 7-person team where I wore every hat. I do my best work on small, fast-moving teams.

Full-stack engineer with 16+ years of software development experience, including ~9 years building B2B SaaS products as a technical co-founder / lead engineer. Strongest in TypeScript/React/Node.js and pragmatic product/system architecture, with ownership across product, backend, frontend and infrastructure. I also created SignalDB, an open-source local-first database with 600+ GitHub stars.
Lately I'm in the spaces between data science and engineering reliable, high-performance, resilient, yet highly-usable tools for scientists and other developers, across the stack. It's a lot of fun.
Some recent projects:
- Performance tuning and infrastructure cost-reductions on https://oceanconnect.ca. It's faster and cheaper to run than ever. Costs are essentially cut in half, and performance across hot paths, on average, is about 30% better. There's now comprehensive observability across the stack, making it so we can rapidly diagnose issues with complex model processing pipelines and data acquisition systems. On top of that, the error rate has dropped dramatically despite increased visibility into what's going wrong (a lot of issues were silently swallowed by OOM culling in Lambda, for example)
- Developing a low-cost solution to autonomously regulate temperatures in 40 saltwater tanks in a remote lab, using equipment which doesn't support remote controls. Using digital potentiometers inserted into each temperature controller, the system spoofs the tank's temperature to trigger heating or cooling, then observes until the correct temperature is reached. It uses several dissimilar redundancies, including a dead man's switch, to ensure there can't be run-away heating or cooling loops. The cost for new hardware with remote control capability came in close to $100K, but this solution (along with supporting software for designing temperature profile time series, monitoring tanks, and viewing historical data) is under $15K, yet required much of the same supporting software work. It's fully compatible with future hardware supporting direct remote control, as well; we'd only need to remove the temperature-spoofing loop and send set points to the units instead.
- A library for analyzing biodiversity datasets, inferring semantics about their data, and then creating a declarative configuration which can be used to transform the data to Darwin Core and validate it. It has a core library that can be used in any kind of client, like a CLI, web API, or a GUI. The declarative configuration makes it so datasets can be worked on in GitHub, then the CLI can run in a workflow to ensure it's still valid as it changes and grows. It uses DuckDB to make assertions about primitive types and data/relational integrity, then uses the application layer to make semantic assertions according to the specification's requirements. The entire workflow is highly supportive to scientists, explaining any issues with the data in very plain terms from start to finish. This has made it so scientists can make old records conform to the standard and have it ready for publishing far faster and with higher confidence than ever. At the same time, it also serves the purpose of helping scientists understand a large, complex standard one field at a time as they work through issues, rather than forcing them to tackle the entire standard from the outset. Ideally, this will lead to them working with the standard earlier and more often, with better knowledge and intuition for how to do so. It's built using Deno, Effect, Qwen 3.5 (for initial semantic inference passes), and DuckDB.
I'm also interested in LLM harness development and creating more deterministic agents with safety and behaviour guarantees.
My work experience is diverse, ranging from SaaS to science to a bit of firmware and robots. I'm interested in just about anything so long as it's genuinely useful, challenging, and the team is excited.

I’m a senior generalist engineer with founding-style ownership. I like building systems end-to-end: protocol and product code, backend platforms, infrastructure, internal tools, and product-facing surfaces. Several times I was either an initial or an early hire in small and large-scale projects and products.
For the last two years, I was a founding engineer at Load Network, an early-stage L1 EVM chain with Arweave-based data settlement. I worked across the stack: developed protocol-level abstractions, consensus and execution clients, bootstrapped infrastructure, DevOps, and smart-contract prototypes. I also built private AI agent harnesses, ran multi-agent tests, and used LLMs for spec review and cross-client protocol design research and data gathering.
Before that, I spent six years in gamedev building backend platforms for massive-scale games at Strikerz/UFL (uflgame.com) and Vizor Games. I was an early hire, working directly with the CTO to build the infrastructure and design the system from the ground up. I engineered microservices for matchmaking, game economy/payments, quests, auth, moderation, and data pipelines (Kafka, Postgres, ClickHouse). I also managed Kubernetes, observability, internal admin tooling in Python/JS, and took part in high-stakes production launches.
I built my engineering foundation in enterprise Business Intelligence and Data Architecture. I shipped large-scale data warehouses (OLAP) for global companies (pharma, logistics), writing heavily optimized Oracle PL/SQL and T-SQL.
Open source: Merged contributions to the Ethereum ecosystem, including the Reth client in Rust, Flashbots SUAVE, and Alloy.
These days, I'm spending more time on product-facing surfaces (React, Rails), exploring Zig, and using LLMs for the right dose of entropy and speed.
Looking for: founding engineer, senior/staff software engineer, full-stack or backend roles where broad ownership and technical depth matter.
