Guo Li 郭立 · Leo · leeguoo
Full-stack Developer
I'm Guo Li (郭立, English name Leo, online as leeguoo). A full-stack developer — I've written code at Qunar and Zhihu, and these days I spend most of my time on open-source tools and writing: small CLIs and AI-agent skills that plug into Claude Code / Codex / your terminal.
What I build
Some open-source projects I maintain:
…and 200+ more repos at github.com/leeguooooo.
Background
Full-stack at Qunar and Zhihu; now mostly independent and open source. Interests: reverse engineering, AI agents, developer tools, and tinkering with the web.
Writing
I write these field notes on the blog: reverse engineering, AI agents, building, and life — in English, Chinese and Japanese. → blog.leeguoo.com
