Software Engineer
Hi! I'm a software engineer with professional experience in infrastructure, databases, system design, and configurations. I earned my master's degree in computer science from UCLA and graduated summa cum laude with a bachelor's degree in computer science from UCSC. In my spare time, I enjoy climbing, reading, editing and filming videos with my friends, and adopting stuffed animals.
