Founding engineer in San Francisco. 0→1 across AI infra, devtools, and mobile.

About

Currently the first engineer at Mesa, where I build core product, API, identity, and agent workflow infrastructure.

Previously co-founded Fastro and was founding engineer at EyeTell and GreenPark Sports. Shipped first versions, found early users, and built e2e systems later teams could operate.

Day-to-day across the stack: TypeScript (web, API, SDKs), Rust (the FS/VCS layer at Mesa), and Python (ML glue, SDKs). Postgres for anything that matters; I pick the rest based on the problem.
