Linux kernel & low-level engineer
I make Linux boot on hardware that was never supposed to run it. Kernel bring-up, board-support packages, Halium/libhybris ports and the compositor plumbing underneath — close to the metal, near the moon.

AVAILABILITY: OPEN TO DEVICE-ENABLEMENT WORK
Kernel bring-up and device trees, board-support packages, Halium/libhybris ports, graphics/compositor plumbing and the boot chain — plus AMD ROCm / LLM inference enablement. I work in the open and would rather tell you a problem is hard than hand you a demo that falls over.
