About Me

Building things
with curiosity.

Hey, I'm Owen, a Math student at the University of Waterloo who'd rather be building something than sitting through lecture.

That same curiosity spills outside of code, too. Lately it's meant teaching myself Japanese, getting lost in stories about ancient historical figures, and watching League of Legends esports.
