About Me!

Growing up between music conservatories and computer labs, I learned early that precision and expression come from the same impulse.

I study Computer Science at Toronto Metropolitan University with a fascination for low-level systems, assembly, and anything that lives close to the machine.

Outside of code, I express myself through photography, mixed media, anything that rewards patience and a sharp eye. The two practices feed each other more than people expect.
