Hi, I'm AarynLu — a backend dev turned indie hacker, based in Shanghai, China.

By day I write backend systems at

Hellobike

. After hours I'm building

Atmos

, an atmosphere for agentic builders.

I write about AI agents and indie hacking. Instead of handwriting every line of code , I care about harnessing AI — defining problems, designing workflows, and turning ideas into systems that actually work.

This is the way I'm exploring what one person can create.
