Always exploring.
I'm Sean, a frontend engineer who makes data legible. By day I build an AI research platform for investors. The rest of the time I write here, mostly in Chinese, draw charts, and climb.
Shanghai, then Hangzhou, then Hong Kong, now the United States. Writing on this site since 2011: 106 essays, eight of them in English.

Projects
- Vert2026
Drop in a GPX track, get a 3D terrain poster. Runs in the browser; nothing leaves your machine.
- Worldlines, Art-isms, Dialectica2026
Three reading atlases: world history, art movements, philosophy. Plain HTML, no build step, timelines you can walk along.
- markvis2017–
Charts straight from Markdown. The thing I made that the most people use, 1.6k stars on GitHub.
- timeline-sankey2022
A Sankey diagram that flows along a time axis, in D3.
- cv_resume2016
A LaTeX résumé template that sets Chinese properly: ModernCV underneath, XeLaTeX, one
make. Over five hundred stars from people who needed exactly that.

Running is the hobby with the most data: 1,702 km logged in Hong Kong between 2020 and 2022, and one UTMB series stone, earned at Translantau 50. Bouldering, up to V9. Tennis: I can rally; the serve is still a project. A ukulele to sing along to, and a ten-hole harmonica for simple tunes, no bends yet.
Two kids, and a podcast in Chinese, Beyond Code.
