Hi, I'm Zhe, a software engineer based in San Francisco.

I've been building software since 2016, across consumer web and full-stack, backend systems, and infrastructure. Currently going deeper on ML and LLMs to support my day-to-day work on new-user cold-start and retention.

I write here about what I'm learning in tech, and occasionally about life. Some of my earlier web-development posts are on Medium, and I cross-post new ones there too.

Outside of work: avid cyclist and coffee lover.
