Top 0.01% nationally; 2nd in Canada, repeated top-20 finishes in programming, mathematics, and physics competitions. $1M+ earned, 100% Job Success, 7,600+ hours, average engagement 330+ hours. I build production AI inside real products, especially Rails/Python systems that need more than a demo. • Multi-LLM failover across Claude / GPT / Grok - 99.9% uptime, zero dropped requests • PGVector RAG 5-10x faster than hosted APIs, embedded in Active Record • AI contract parser shipped in 3 weeks with OCR fallback and source-document backlinks • 1M-row pipeline cut from 90 minutes to 30 seconds for an industrial dashboard where downtime costs millions 25 years shipping software: Rails 15 years, Python 8 years, Node, .NET, PostgreSQL/vector search, F#, Clojure, Scala, C/C++, scraping, and data pipelines. Former CTO: grew a company 12x from $20K/mo to $250K/mo, hired engineers, set direction, and still wrote the hard code. Send me the product, the stack, and what the AI needs to do. I respond fast and only take projects with a clear path to value.

AI/ML Engineer & Full Stack Developer | Python • PyTorch • Agentic ai • React • TypeScript I build machine learning systems and full-stack web applications. AI/ML: Reinforcement learning (actor-critic, PPO, genetic algorithms), deep learning (TCN, LSTM, MLP), LLM integration and automation, model training and evaluation in PyTorch and TensorFlow. Full Stack: React, Next.js, TypeScript, Python (Django/Flask/FastAPI), PHP/Laravel, Go. 4+ years production experience at TeamGantt. What I've built: - Multi-asset algorithmic trading systems using deep RL and temporal convolutional networks - Walk-forward optimization framework for systematic strategy evaluation - Go-based trading broker with REST API and real-time streaming - Production features in React/TypeScript/PHP/Clojure serving thousands of users Background: Controls engineering + Virginia Tech AI & Machine Learning program (completing 2026). I deliver fast, communicate clearly, and write tested code.

My software career started when I was 14, with writing Ruby web apps for small businesses, freelance collectives, and failed startups (Instajournal anyone?). Now, another 14 years and hundreds of projects later: - I've built reactive web apps with React and reactive desktop apps with QtQuick; - I've worked on blockchains as well as an alternative to blockchains (Holochain); - I've designed low-cost zero-maintenance cloud apps comprised of AWS or GCP services; I've also managed custom baremetal deployments. - I've maintained an innovative Linux distribution (NixOS); I've even worked on Linux kernel device drivers. What I can bring to the table: - Breadth. Instead of trying to force a square peg into a round hole by implementing a technology that doesn't align with your use case, I can select something that's tailored to your domain. - Depth. If what you're trying to do is best solved with a patch to the operating system, the database, or the programming language, that's what I'm going to do. And have done before. - Security. - Simplicity. I have extensive experience with Clojure, Rust, Python, Ruby, Elixir, Erlang, Go, Rust, Java, JavaScript programming languages and their respective ecosystems. When it comes to DevOps, I'm familiar with NixOS (commit access since 2017), NetBSD, OpenBSD, RHEL, Debian. I have designed cloud application architectures using various AWS and GCP services. I'm a fan of React for web and Qt for desktop. I'm well versed in use of modern cryptographic primitives, from signatures to PAKE. I work Monday through Friday from 9 to 5 Eastern (13 to 21 UTC). Send me a message and let's figure it out!
