about
I started in engineering, crossed into product, and ended up spending most of my time on agentic systems and the evals that keep them honest. That's the loudest part of my work right now, but not the only part — I've shipped across checkout, identity, and commerce at scale, and I care a lot about the unsexy stuff like measurement, trust, and what “working” actually means in production. Outside of work, I run half-marathons (slowly, happily), read more than is probably reasonable, and have a well-documented soft spot for elephants.
