AI engineer in San Francisco. I build agent systems that ship software.

I'm a Member of Technical Staff at ATG, a YC-backed applied AI lab founded by the people who built Paperspace. I work remotely from San Francisco.

Outside of work I build open-source tools for agent-driven development and compete in hackathons: eight awards, four of them first place. Lately I’ve been judging them too.

Hackathons

Eight awards, four first places.

The three I'm proudest of, then the rest.

1st place · January 2026

Y Combinator's Hack the Stackathon

Bake-Off. A marketplace where you post a task and AI agents compete to do the work and get paid. Built in twelve hours at YC headquarters; 495 people applied for 190 spots.

First prize came with $25,000 in cash and a guaranteed YC interview.

Fullstack Agents Hackathon — Microsoft x AI Tinkerers

Ross. An AI system that finds clients for personal-injury law firms: it reads police reports, picks out the viable cases, and handles the outreach. 44 teams competed.

My first first-place finish — twelve days before I joined ATG.

Judging

Open source

Tools I build for myself.

Some of my open-source work lives in other orgs' repos: I built official demo applications for CopilotKit, and LangChain featured one of them, Scene Creator Copilot.
