Previously he drove full-stack platform and performance work at Airbnb and Groupon, inventing declarative isomorphic patterns and cutting page load times dramatically.

A pragmatic tinkerer at heart, he’s known for embedding ML in the client to balance privacy and engagement while keeping core web vitals performant.
