About

My journey bridges science and technology. I hold a HBSc in Bioinformatics from the University of Waterloo, where I co-authored a scientific publication on probiotic delivery, and I recently completed a Computer Systems Technology diploma at BCIT, focusing on full-stack development and systems design.

Outside of work, I enjoy exploring new technologies, building side projects, entertaining my cats, playing pickleball, or watching baseball - Go Jays!
