I am a Member of Technical Staff at OpenAI. Previously, I was the third engineer at Promptfoo, the most popular open source tool for LLM evaluation and red teaming, acquired by OpenAI in Spring 2026.

Before that, I led engineering at a YC-backed private equity startup; built quantitative models of reputation in the fine art market; researched how blockchains can be used to make voting and ownership fairer and more efficient; built an auction house; and co-founded / sold a collectibles marketplace.

I maintain an artistic practice and have shown work with galleries in NYC, LA, Austin, and Tokyo.
