I'm LuMaRen, an indie developer in Shanghai. 10 years of experience: from web front-end (JS/TS/React/Vue) to game front-end at Ximalaya (Cocos Creator), leading core dev for a large-scale DAU product. Now building with Python, Electron, Tauri and AI Agents. What fascinates me is turning abstract logic into experiences people can feel. I take on client work while incubating my own products — FateMesh, SpaceRoam and more.
No need to dig through pages — just ask. Projects and posts I mention are one click away.

All notes ↗I like building things that are creative — but not just for looks. I want every piece of work to have real thinking behind it, and I'm happy to take on real challenges.
Solve the real problem first; pursue your own expression second.
