I live in San Francisco and grew up in Eastern Europe. I studied at Dartmouth College and work as an early employee at a consumer AI startup.

Lately, I've been investing tons of time in automating end-to-end ML engineering tasks with coding agents, creating agent skills, and how to engineer luck. I use this site to keep track of my work and the books I'm reading.

Projects / Ventures
