Yu Huizhen

I am JasonYHZ on GitHub, based in Osaka, Japan. I write about software engineering from the practical edge: fast interfaces, reliable services, developer tools, and the trade-offs that appear when systems meet real users.

This site is intentionally personal. The goal is to publish clear technical notes, field reports, and durable references that remain useful after the implementation details change.
