Worked on the cs-pub-ro/hardware-software-interface repository to enhance Lab-02 by refining its documentation, test infrastructure, and build alignment. Focused on improving clarity for students and instructors, the work included updating segfault guide references, expanding pointer reading materials, and correcting Makefile paths to ensure reliable test execution. Leveraged C programming and Makefile management skills to align test names with support functions, reducing confusion and test failures. Emphasized debugging and testing throughout the process, resulting in more maintainable course materials. The improvements addressed both instructional guidance and technical reliability, supporting a smoother experience for users engaging with the lab environment.
