01 · About

Protocol-minded. Product-obsessed.

I design and ship end-to-end blockchain products — contracts, backends, and interfaces — with a bias toward systems that are usable on day one and resilient at scale.

From on-chain social on AO Computer to payments on Internet Computer and music streaming with automated royalties, I work where crypto rails meet real product craft: clear UX, strong security posture, and shipping velocity.
