About Me
Hello, I'm Yi Liu — LiLittleCat online.
I'm a software developer. I enjoy understanding how systems work, building reliable software, and using AI to learn new tools, ideas, and ways of solving problems.
Outside work, I maintain open-source projects and build developer tools. You can find them on the Projects page.
About This Site
This site is my long-term notebook for software, AI, tools, and things I learn along the way. The name yl.do combines my initials, YL, with “do” — a reminder to keep learning, building, and turning ideas into working things.
