Embedded Firmware Engineer
Built and integrated bare-metal UPS firmware on STM32H7/H5, improving fault handling and real-time reliability across battery, inverter, and PFC control paths.
Built and integrated bare-metal UPS firmware for STM32H7/H5 platforms across battery management, PFC, and inverter control subsystems while improving startup sequencing, protection logic, and real-time stability under edge-case fault conditions; collaborated with hardware and validation teams to tune control loops and diagnostics, reducing recovery time and increasing system reliability in production-oriented test environments.
