About Karina

My story

Lived in five countries. Studied three majors. Curiosity is my superpower.

Information management in Taipei, industrial design in London, HCI at UC Santa Cruz. Twice a founding designer, and a designer inside 4,000-person Binance. I design so the business and the user both win.

How I leadDesign reviews with PMs and engineers before every handoff, one design system from Figma to code, and prototypes in Claude so the team decides on working software.
