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

I lead applied AI for Codex in APAC and back early-stage AI companies.

Today I lead applied AI for OpenAI's Codex in APAC, based in Singapore. 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.
