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!

Hey! Call me Alex. I enjoy introspecting, consuming/creating good stories, solving puzzles, and jamming on Spotify. Since childhood, one of my biggest dreams has been to have the ability to fly, but I might have to settle for telekinesis or teleportation since that's very unlikely.

Hey all! I am a 3rd year CS major. I spend my time not understanding CS, making more food than my housemate and I can finish (help), and wishing I had more time to play board games/card games/Tabletop RPGS. I also play a niche sport from Germany where I get to hit people, so that's fun too (<- ask me about this if you want a chance to hit me). Feel free to talk to me about CS or anything else that interests you!

Hello! I'm a third year CS major who started studying CS because of Neopets! I love coffee ice-cream (but don't drink coffee) and watching cooking shows (but I can't actually cook). You can always find me raving about the TV show The West Wing or trying to get my friends to play games with me. When I was in kindergarten, I used to teach an imaginary class on my small whiteboard; six-year-old me and twenty-year-old me are overjoyed to have a real class to teach now. 🙂
