CS Major @ Cornell

Gabriel Castillo

I'm Gabriel, a Computer Science major at Cornell University.

I have been learning to code since I was 12. Having started with learning Python to build simple programs to learning JavaScript to use React Native to build cross-platform mobile applications, I have spent the last 6 years falling more and more deeply in love with Computer Science. Currently, I am learning PyTorch and C++ to dive into AI and highly efficient algorithms. Besides that, I am developing some cross-platform mobile apps in order to launch a start-up.

During my free time I enjoy going to the gym, playing piano and listening to music.
