──────────────────────────────────────────────────────────────────────────

I build software with my hands on the keys. Mostly local-first tools, developer experience, and the parts of products that have to feel right — the typography, the shortcuts, the empty state, the quiet click. Currently between San Francisco and Montreal.

>experience

CTO · 4×

Engineering leadership across four startups, seed through Series B. Hired, shipped, scaled — and stayed close enough to the code to know which lines hurt.

Founder · 2×

Built two companies from the napkin up. b2b and b2c. Two very different ways for software to disappoint people, two very different ways to make it not.

Meta · Engineering

Infrastructure and developer tools. The systems other engineers stand on. The stuff you only notice when it breaks — so the goal is, you don't.
