[01] About

From founder to the person builders call.

I spent more than fifteen years building web products: shops, services, and the training around them. In 2020 I went back to code, this time in Web3. I co-founded FiftyWei, shipped on the Ethereum hackathon circuit, and most recently led Developer Relations and Customer Success at iExec.

Today I build AI agents and the tools around them: MCP servers, agent wallets that ask a human before acting, guardrails and evals. Years of developer relations taught me where people get stuck, and how to support them until they ship. AI lets me scale that support beyond what one person can do.
