My name is William Cai. I am a recent graduate student from University of Massachusetts Amherst, with a Master's degree in Computer Science. I have created this website to share my learning on select topics in computer science, especially AI.
In my time at UMass Amherst, I had a fun, productive, and enjoyable life with great friends and teachers. I have taken many interesting and profound CS courses covering a wide variety of fields such as algorithms, software engineering, data science, web development, and of course, AI. I have learned so much from these courses and worked on numerous projects. Now that I have graduated in Spring 2026, I look forward to a career in software development, full-stack web development, or agentic AI in the future.
