Worked on the nxp-upstream/zephyr repository to enhance stability and reliability in embedded systems, focusing on timing and Wi-Fi subsystems. Addressed two critical bugs by stabilizing the M33 system clock timing, ensuring accurate delay functions, and improving Wi-Fi scanning by guarding against null pointer dereferences in driver code. Applied consistent clock handling across multiple SoCs, aligning with existing patterns to maintain cross-platform reliability. Demonstrated technical proficiency in C programming, driver development, and firmware engineering, with a methodical approach to debugging and code maintenance. The work reduced crash risks and timing errors, contributing to more robust embedded system performance during the period.
