How I work
-
Evidence before opinion
Analytics, usability tests and A/B tests decide, not the loudest voice in the room. I bring numbers to design reviews.
-
Design the whole journey
Cart, upsell and checkout are one decision for the customer. I design across the steps, not screen by screen.
-
Systems that scale
Design systems and shared standards let small teams ship consistent work across many products and markets.
-
AI in the workflow
I use Claude, Claude Code, Cursor and Figma Make to prototype and test ideas as working software, early.
