Worked on refactoring the WLAN subsystem in the nxp-upstream/hal_nxp repository to introduce configurable logging, focusing on improving observability and maintainability of the firmware. The approach involved replacing raw PRINTF statements in the C codebase with macro-based logging using wmlog.h, aligning with Zephyr logging conventions and supporting standard log levels. This allowed for suppression of debug output in production, reducing log noise and enhancing troubleshooting. The update also standardized line endings and addressed a specific configurability issue, demonstrating attention to code quality and repository standards. Utilized C programming, embedded systems knowledge, and firmware development expertise throughout the project.
