About

I come from an industrial design and data science background — a mix that shapes how I work: industrial design taught me to design for real use, and data science means I can reason about the numbers behind a product, not just gesture at them.

That mix is why I work end to end. I take ambiguous problems from strategy through to shipped product — increasingly directly in the codebase, prototyping with AI coding agents and shipping my own production PRs (50+ and counting). It's where the polish that usually dies in handoff survives: smoother interactions, error states that build trust, the details nobody specs.

Outside of work, I'm a rock climber who loves treating a route like a puzzle to solve with friends.
