About

I'm Caellum — a software engineer and Computer Science student at the University of Toronto. I build across the stack: AI/ML pipelines, full-stack web apps, and games. I like turning messy, ambitious ideas into things people can actually play with.

Most recently I overhauled an AI game-development pipeline at Chatforce, ship for non-profits with U of T Blueprint, and run my own indie studio, Bronze Bat Studio — whose titles have crossed 3M+ plays. In between, I win hackathons.
