About Me

I'm a graduate student at Stanford University who is also working at Roblox as a backend engineer. I went to UC Berkeley for my undergrad, and have been a SWE intern at GoDaddy and Wish in the past. At UC Berkeley, I was an uGSI for CS 186 (Databases) and CS 61C (Computer Architecture), and also served on course staff for Data 8, Data 100, and EE 16A. I have also served as an advisor and a course co-coordinator for the executive board of Berkeley's Computer Science Mentors and the treasurer of Upsilon Pi Epsilon, the Berkeley CS Honor Society.
