Hello! I'm a third year CS major and 61B was my favorite class (actually I decided that I wanted to pursue CS after taking it). I enjoy cooking, playing Hearthstone and League of Legends, and of course, browsing memes. Feel free to hit me up and talk about anything!
akazorian (at) berkeley.edu
Hey everyone! I'm Alex and I'm a junior majoring in CS. Cool fact: one of my proudest accomplishments is a 10+ page paper on Kanye West’s “The College Dropout”. If you ever find me, I’m probably procrastinating by looking for new music or watching/playing basketball. Feel free to talk to me about anything like Kendrick Lamar, Radiohead (being the best band of all time), the Lakers, or how amazing HashMaps are.

Hello! I'm a third year EECS and Music major. I grew up in upstate New York and finished high school in Kentucky. In past semesters, I TA'd EE16A, but am now jumping ship to the CS side. On Sundays, you can hear me playing (trying to play) the Campanile bells. In my free time, I like to play tennis and throw around frisbees. My favorite restaurant was Eatsa, until it closed. Looking forward to meeting all of you!
