About
Mission. Raise a generation of engineers who delete more lines than they add — and whose systems run faster because of it.
Most code is overweight. Most systems are over-engineered. This school trains the opposite reflex: what can I remove, compress, inline, or simply not build at all? Every capstone is measured twice — once in features shipped, once in lines deleted.

“I deleted 2,400 lines of React in week three. Tests still pass. I feel light.”
“Solid open-weights module. I co-taught one session and learned something about quantization I'd been hand-waving.”
