Growing up in Hong Kong, I fell in love with design before I knew what to call it. Billboards, neon signs, and posters are everywhere. The city always has something to say.

About

A little about me

As a kid, besides spending time drawing comics and making zines, I was obsessed with SimCity 2000 (best installment, fight me on this). The game interface and the isometric perspective graphics fascinated me and I didn’t realize it was called UI design. At 13 I had a revelation in a Tokyo subway station about what good information design can actually do.

I was trained as a graphic designer, then found UX by following what interested me — good design can bring clarity and make people feel. After all these years working in design, I still feel like that kid who enjoys making things and is always curious about what’s out there to keep honing my craft and leadership skills.

Advocating for users who aren’t in the room when a team makes important product decisions, helping a team shape a rough idea into something we are proud of, supporting designers building their careers, these are the parts of leadership I am most grateful for.

When I'm not designing, I'm always hunting for the most perfectly drawn transit map from every city I visit, trying new recipes, and spending time in nature.
