About Karina

My story

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

I grew up in Taipei in a family of engineers and studied information management there, then industrial design in London and human-computer interaction at UC Santa Cruz. I have been a founding designer twice and a designer inside 4,000-person companies like Binance, always with engineers, PMs and the whole cross-functional team in the room. I build for the business and for the person on the other side of the screen. Both have to win.

How I leadI run design reviews with engineers and PMs before every handoff, and own the design system end to end, from Figma variables to the code tokens engineers ship. At Binance I aligned 2 senior PMs, 3 senior designers and 4 senior developers on one fraud tool. I prototype in Claude so the team decides on working software, not static screens.
