Worked on reliability improvements for early boot memory allocation in embedded firmware, focusing on the DXE GCD initialization process. Addressed a bug in the tianocore/edk2 repository by updating the memory type selection logic so persistent memory correctly takes precedence over special-purpose memory, aligning implementation with intended behavior. Applied the same fix to microsoft/mu_basecore through a cherry-picked commit, ensuring consistency across repositories. Utilized C programming and system programming skills to enhance platform stability and reduce the risk of memory misallocation during boot. Maintained strong code hygiene and clear documentation, demonstrating effective patch management and cross-team collaboration practices.
