Li Zimu

Full-Stack Engineer & AI Engineer

I work across product interfaces, backend services, AI integration, and deployment. My focus is turning useful ideas into systems that can be used, operated, and improved in the real world.

This site is where I write about engineering decisions, AI product building, reliability, practical tooling, and the path from prototype to production. The work section collects selected systems and engineering patterns without pretending they are client case studies.
