Hacker¹, occasional writer, infrequent investor, ex founder.

Founding data scientist and engineer at Replit, where I built large-scale data infra for training & agent development², trained SOTA models³, and led data and PLG efforts after launching the world’s first coding agent. Joined at <$1m ARR. Left at well over $100m ARR.

Before that, I founded and scaled Uniwhere to acquisition. Used by 600K+ students, 1/3 of the entire market, it was Italy’s first college career management app.
