Over mij
I am Jeff Liu, an embedded firmware engineer focused on automotive IoT & OBD-II trackers. I work with STM32, GD32, nRF54 series, Zephyr RTOS, CAN/LIN bus, GPS & IMU and 4G cellular modules.
I provide C/C++ firmware coding, CAN parsing, OBD protocol development, 4G communication design, hardware debugging, bug fixes, PCB review and technical docs. I build stable production-grade code for vehicle telematics and automotive peripherals.
I help implement reliable 4G uplink, fix communication issues and optimize power consumption for mass-produced automotive IoT hardware.
