A little about me

I’m a third-year Mechatronics Engineering student at Waterloo. I enjoy understanding the full path from a signal at a connector to the information someone sees on a screen.

My experience spans PCB design, embedded C, and desktop software, alongside running Charles Tech and working on university robotics projects.
