Who makes Mint

Hi, I’m Yukun.

I build apps, experiments, and the occasional mechanical keyboard. Rosy or Leo is usually nearby.

These days most of the typing is done by coding agents, and my job is to hold them to account. Every number on this site is a measurement I ran on a real machine and can run again.
