"If it runs on silicon, I've built or broken it"

About

I'm an independent R&D engineer working at the intersection of computation, physics, and systems design. My expertise spans quantum-scale simulations, custom operating systems, kernel development, and hardware reverse engineering.

From bootloaders to biology simulations, I approach systems from first principles, often reconstructing them entirely. My work includes AI systems, compiler theory, custom programming languages, and systems security tooling.

"If it runs on silicon or simulates the real world, I've built or broken it."
