Independent developer in Shanghai

Software with endurance.

I build practical products for runners, families, and everyday life. This site is a working notebook for shipped apps, writing, and the lessons that carry over from long miles in the mountains.

What this site holds

Three threads, one practice.

Product work, writing, and running all inform the same thing: disciplined progress over noise.

Build

Independent products

Small, useful applications with clear scope, calm interfaces, and a bias toward long-term maintainability.

Write

Notes worth keeping

Short essays on product craft, endurance, and what repeated practice teaches better than theory.

Run

Endurance as a lens

Trail running and racing sharpen how I think about pacing, resilience, and decision-making under fatigue.
