About

Engineer. Builder. Shipper.

I build products at the intersection of AI agents and crypto infrastructure. On-chain identity, agent-to-agent payments, skill marketplaces, prediction market tools. Everything I build, I share — the code, the process, the lessons.

Based in Salt Lake City. Building with OpenClaw. Shipping every day.
