Senior Full Stack & Agentic AI Engineer
Building production systems end-to-end - with or without a playbook.
About
I build apps. I build agents. Sometimes I let the agents build the apps.
My career started with React components and somehow evolved into autonomous agents that make their own API calls - I'll let you decide if that's progress. I work end-to-end: Next.js and TypeScript up front, Node.js and FastAPI in the back, PostgreSQL holding everything together, and LLMs doing things that are technically my responsibility. Seven years of production systems has taught me one thing: the bug you're most confident about is always the one.
