Master student majoring in CS at USTC, hobbiest programmer and passionate geek. Mostly a developer, often a DevOps engineer and Linux SysAdmin.

Python, C, C++ and Go are my primary options for course labs and new projects, though I always like trying something new (and that’s why I have a little taste of everything).

Also loves casual and puzzle gaming.

I’m an active contributor on GitHub across various repositories. You can see a list of all my pull requests using GitHub search.
