BANGRUI FANG

I’m Bangrui — a second-year Computer Science student at McMaster University, originally from Hefei, China.

I’m drawn to problems where the difficulty isn’t writing the code — it’s understanding what’s actually happening underneath. Concurrent systems, machine learning pipelines, and the tooling around them are where I spend most of my time.

I built a handwritten digit recognizer from scratch — not to pad a portfolio, but to trace the full path from training loop to browser inference and understand where each decision matters. That’s how I approach most of my work: start from the mechanism, not the abstraction.

I care about software that is technically honest, structurally clear, and built with enough restraint to stay useful. I also photograph — mostly as an exercise in observation.
