Hey there! I'm a 3rd year EECS major from San Jose, CA. This is my first time as a TA and I'm super excited to meet you! Besides being on course staff, at Berkeley I'm involved in Computer Science Mentors. In my free time, I like to play guitar (and maybe record a few covers if I'm feeling brave) and fangirl about the latest book/movie/TV show/song I consumed. If you ever have any questions about 88, classes, clubs, or professional development, feel free to reach out :D
