Worked on firmware reliability by addressing SMBIOS Type 20 Extended Address display issues in both the tianocore/edk2 and microsoft/mu_basecore repositories. Focused on correcting the structure used for printing Extended Starting and Ending Addresses in SmbiosView, ensuring accurate hardware inventory reporting. Applied the initial fix in edk2 and maintained consistency by cherry-picking the change into mu_basecore, demonstrating disciplined cross-repository collaboration. Utilized C programming and system programming skills to enhance data accuracy and maintainability. The work improved the robustness of firmware reporting tools, reduced the risk of incorrect inventory data, and contributed to higher code quality across both codebases.
