Jimmy Cai
I'm a master's student in Computer Science. I'm currently working on my thesis and expect to graduate at the end of 2026.
I like building things and exploring new tools and ideas, mostly around the web tech stack. I enjoy writing code that is elegant and efficient, and putting everything together to make something useful and beautiful.
Sometimes I write blog posts here, mostly in Chinese but sometimes in English, about my daily life and the things I'm learning.
