I like AI agents, simulation and space. I build software, run experiments, and think about megastructures like the one on this page.

About
I'm Jerry. I'm from Toronto, and I study computer science at the University of Waterloo as a Schulich Leader.
Space is the thing I find coolest: Dyson swarms, asteroid mining, and science fiction that takes its physics seriously, like the Xeelee Sequence. The cover of this page is that interest with the arithmetic done.
I also love AI agents, simulation, and making things people use. Most days I'm building alongside coding agents.
Work
Software people use: AI video at a YC startup, a counter-drone turret, and a math judge in 182 countries.
Waterloo Defence
I co-founded a student team building an autonomous counter-drone turret, and lead its software: finding the drone, tracking it, and aiming ahead of it. Our detector beats fine-tuned Ultralytics YOLO and Roboflow RF-DETR models on the same drone benchmarks.
TopsOJ
A judge for competitive math I started in high school. Over 100,000 people in 182 countries have used it.
Quoted Tech Computers
Automated label printing and competitor pricing, cutting manual processing time by 70%.
Research
Four sole-authored papers, on coding agents and on binary stars.
Verifying the Second Agent
Do more coding agents fix more bugs? In controlled experiments, trees of agents spent 6 to 12 times the tokens for no gain.
Mass transfer in binary stars
Three papers showing that gas passed between two stars shrinks their orbit, where the textbook says it usually widens.
Projects
Hackathon builds and things I made because I wanted them.
Cardboard Cockpit
A flight simulator you fly from a cardboard cockpit and a webcam.
Daedalus
Sculpting in 3D with your hands in the air.
Drift
Turns the wait for an AI's answer into a short, focused break.
Worldline Engine
A universe simulator where one seed always grows the same universe. The cover of this page grows the same way.
Porchlight
An aid dispatcher run by agents, which hands anything sensitive to a person.
PolyTwist
Solves and renders twisty puzzles it has never seen.
Record
Scholarships, papers and contest results.
