Los Angeles · 2026
I'm Jin — a machine learning engineer in Los Angeles. I write about applied AI, evaluation, agents, model behavior, and the gap between impressive demos and tools people actually want to keep using.
Some posts are more considered. Some are notes from the middle of figuring something out. Some are just things I wanted to pin down before they slipped away. Sometimes an interesting chat with AI ends up here too.
You can find me on GitHub, by email, or via RSS.
