Where did you grow up? What was your path to Cal?

I grew up in Camarillo, California which is a small city 20 minutes north of Malibu in social. I knew I wanted to do some sort of engineering throughout high school but I didn’t even know what computer science was all about until I got here. I was deciding between UCLA and Berkeley my senior year and chose Berkeley after being lured in by the abundance of opportunities in the EECS department.

How much programming have you done (& what languages)?

I’ve been programming for two to three years. I stared with Python in 61A and then learned Java, C, C++, and RISC-V. I also have experience in Javascript, HTML, CSS through Angular and web development.

What are your hobbies

I love being active, especially playing basketball or any sports. I love to hike, explore, and travel to new places and discover beautiful landscapes and view points. You’ll also always find me hanging out with my friends, chilling in our apartment.

What are some of your talents and skills?

I can stand on my tippy toes for an incredibly long period of time (which I get made fun of by my friends all the time). I also used to play the guitar and piano and am good at video editing and photography.

Have you done anything remarkable? Has anything memorable happened to you?

I’ve climbed the tallest single standing sand dune in North America this past summer in Boise, Idaho.

What commitments will be consuming your cycles this semester?

In addition to teaching this class, I will be taking CS162 and EE149 along with being a coordinator for Computer Science Mentors.

Hey everyone, I am a third year studying cs and philosophy. This is my third semester teaching 61c, and I am very excited to share this journey with y’all. A little bit about my teaching style, I like to focus on concepts. That doesn’t mean I repeat information from lecture and you can attend my discussion as substitute for lecture. That is not my goal. My aim is to get into why some design decisions are made certain ways, and please come to my section if that interests you. Outside school I spend a big chunk of my time exploring the outdoors.

Hello! I’m a junior from Los Altos California, and I’m super excited for CS61C this semester. A bit about me: I code exclusively in binary. My first love was an XOR gate. I have 29 levels of caches on my computer. My main goal this semester is to blow up, then act like I don’t know nobody.

Hi, I’m a third-year EECS major and this is my 3rd time TAing for 61c. In my discussions, I like to start with a small mini-lecture to go over recent material, and then jumping in to the problems! Outside of classes I like to design and create things in the makerspace, dance (I’ve directed an AFX team), and explore restaurants around East Bay and SF

Hi, I’m Ryan, a third year Computer Science major from St. Charles, IL. I enjoy music, creating and discovering new things, and I survive on coffee. I hope to have a wonderful semester with you all!

I value group work and collaboration in my discussions. I plan to conduct a brief review of foundational and current topics, then dive into working on the worksheet in groups and as a class. I don’t promise to get through the entire worksheet, but my goal is to make sure everyone gains a good conceptual basis for the material.
