Worked on stabilizing the AArch64 build process for the Memory Protection Exception Handler Library in the microsoft/mu_plus repository, focusing on improving build reliability and maintainability. Addressed a recurring compilation issue by removing a non-existent header inclusion, which reduced build failures and streamlined continuous integration feedback. Collaborated cross-functionally to ensure code hygiene and set the foundation for broader AArch64 platform support. Utilized C programming and system programming skills within an embedded systems context to enhance the build process. The work concentrated on bug resolution rather than feature development, emphasizing careful code review and incremental improvements to support future development efforts.
