Working on

Clinical AI at Abridge — AI-generated clinical notes where reliability is the product, and the eval systems (LLM-as-judge calibration, promotion gates) that keep them trustworthy.

Building

This site, with my own Claude Code workflow — the colophondocuments exactly how. Also: yexin 野心, a career intelligence engine, and a steady stream of small agents and tools.

Writing

Mia Builder 手记 — essays on agent design, eval methodology, and creator identity in the AI era, mostly in Chinese, on 小红书 and here.

Life
