Builder • Engineer • Entrepreneur

I'm a builder at heart.

Serial entrepreneur and software engineer passionate about product design, engineering, and turning early-stage ideas into real-world impact. I've been coding since age 12, studied Neural Biology and Computer Science at the University of Toronto, and left in my fourth year to pursue entrepreneurship full-time.
