## About

JingYu (景煜) trained as an architect and now builds software, using AI tools rather than writing code by hand. jingyubuilds.com is the record of everything shipped — with years, honest numbers, and the things that stopped — plus short first-person posts about building. Long-form essays on Chinese history and culture are a separate publication, Old North Whale, listed below as one of the things built.
