Professional Summary
Senior product designer with 7 years shaping consumer and B2B products at scale. I lead the design end of zero-to-one bets and refactor 0 → 1 wins into design-system patterns. Focused on the craft + measurement loop: pixel polish that holds up against the metrics it's supposed to move.
