At comma.ai, I build and ship openpilot across STM32 firmware, the Linux kernel, OS releases, and Python/C++ services. I’ve contributed more than 200 merged PRs and ported the first VW MEB car, the ID.4.
I cut STM32H7 idle power by 77% through clock gating, voltage scaling, and deep sleep. I also designed and produced a dual-stack, 4-layer PCB adapter for PSA cars and brought up external GPU support over USB4/PCIe.
At ABB, I developed measurement and monitoring relays end to end, from ARM Cortex-M FreeRTOS firmware through certification. I also automated build, test, and release workflows and coordinated TÜV, CE, UL, CCC, and EMC/environmental testing.
