Three scales. One throughline.
Production work with real users on the other end — plus the proof that it holds up.
I turn ideasinto products peopleactually use.
AI engineer & builder — Google-scale agents, clinical AI, and a steady stream of things made for fun.

Where ideas become products
Three very different scales, one throughline: take a fuzzy idea, carry it to something real, prove it holds up. Google-scale consumer agents. Zero-tolerance clinical AI. Small delightful things on weekends.

How I work
↓↓Ship it
An idea only counts when someone else can use it. Real products, real users, real feedback loops.
Prove it
Evals, promotion gates, honest failure modes. If it can't be verified, it isn't done.
Enjoy it
Craft and taste are not optional extras. The small delightful details are the point.
Have an idea worth building?
