About

Portrait placeholder

Hey, I’m Joel!

I’m a Calgary high‑school builder focused on accessible health tech. I lead OncoSense, a portable AI ultrasound initiative. I like fast experiments, clear metrics (Dice/AUC, FPS), and privacy‑first, on‑device AI.

Recent highlights: CWSF Bronze • Samsung Solve 2nd + Fan Favourite • Pfizer Oncology Award • Spartan Controls Innovation.
