Worked on reliability and correctness improvements in embedded systems and kernel development, focusing on C programming within the nrfconnect/sdk-zephyr and zephyrproject-rtos/zephyr repositories. Addressed safety issues in ADXL decoder drivers by replacing unsafe pointer casts with type-safe uintptr_t arithmetic, eliminating build warnings and ensuring robust offset calculations for sensor data paths. Enhanced kernel test reliability by resolving a race condition in the timeout_order test, shifting from fixed sleep intervals to semaphore-based synchronization for event-driven behavior. Applied static analysis best practices to suppress unused-return warnings, contributing to more maintainable code and stable continuous integration workflows across both projects.
