$ cat about.md

Backend leader on FineX at FanRuan — building no-code & IAM SaaS and digging into database internals. I like turning fuzzy, "can't-be-done" ideas into shipping systems.

Off the clock I'm chasing JRPG endings, falling down ACG rabbit holes, and hunting good light with a camera. Currently leveling up in deep learning & LLMs.
