Enterprise AI operator, software engineer, startup founder, product builder, early-stage AI investor, and professional photographer.

I lead enterprise deployment for Codex and back early-stage AI companies.

Today I lead enterprise deployment engineering for Codex at OpenAI. Before OpenAI, I led enterprise work at Scale AI, cofounded Bild, and worked in product and engineering at Amazon and Apple. I also invest in early-stage AI companies and photograph landscapes, wildlife, and people around the world.

The work I like sits between technical possibility and practical use.

At Apple that meant cryptography and security. At Scale AI and OpenAI, it means helping companies deploy AI. In photography, it means deciding what belongs in the frame.
