About
I'm Mayphus Tang, based in Hangzhou. Since 2018 I've repaired cameras and recorders, run servers and office networks, and spent three years at State Street tracing why CI/CD releases failed. I still like small boards, networks, and cameras that refuse to boot.
Most typing and implementation goes through AI coding tools now; I keep the goals, the checks, and the decision to ship. This site is my public notebook—evidence, limits, and links included.
