About Me!

Who I Am

I’m a Computer Science student at Toronto Metropolitan University. I recently interned at Tesla, programming machines in real-time to improve the production line. On the side, I teach programming to all ages and build creative projects. Outside of coding, you can find me creating art and music!

I pursue computer science with a passion in creating systems designed for longevity, without compromising creativity.
