About · The designer

Design things that matter.

I'm Chi — a Taiwanese-British lead product designer with over 10 years across healthtech and fintech. I focus on 0-to-1 product design, data visualisation, and consumer-facing growth design.

I bring strategic thinking and high-craft execution, from early discovery and systems design through to pixel-level delivery. Currently open to roles in London and remote.
