CTO @ Cosine

profile

πŸ‘‹Heyo {visitor},

I build things that help people build things.

Currently CTO at Cosine AI where we're building Genie β€” an autonomous AI software engineer that can read your codebase, write code, and ship features like a human colleague would.

In other news check out some of my πŸ‘¨β€πŸ”§ projects, πŸ“ writing or drop a follow on 🐦 twitter to reinforce my vanity.

K thanks bye.
