About

I’m a builder focused on one thing: shipping systems that hold up in production.

My work sits at the intersection of smart contract architecture and full-stack product delivery. I design and implement on-chain logic, then wire it into practical backend and frontend systems that users can actually operate day-to-day.

I care about deterministic testing, observability, and clean execution pipelines. If the brief is “we have an idea but need it live,” that’s where I do my best work.
