About Karina

My story

Three continents. Five homes. Thirty countries. Curiosity is my design tool.

I grew up in Taipei in a family of engineers, then studied product design in London and human-computer interaction in California. I have been a founding designer twice and a designer inside 4,000-person companies like Binance and Grab, 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.
