Sebastián.

I am a Brooklyn-based computer science professor and programmer. I was born in Mexico City, and later moved to New York, where I studied at NYU.

Although I mostly deal in the introductory and video game programming pedagogy space, I also have experience in other areas of computer science.

Outside of work, some of my interests involve learning foreign languages, music, and obsessing over espresso.

Students can schedule office hours with me here. You can find me on GitHub if you would like to check out my work, on LinkedIn, or via e-mail.
