About Me!

Who I Am

I’m a Computer Science student at Toronto Metropolitan University. So far that has meant real-time control software on a factory floor, a full-stack healthtech app, a multithreaded C++ engine, and teaching Python and Java to high schoolers. I like having range more than I like having a label, and I’m in no rush to pick one.

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