Worked on firmware robustness by addressing certificate data alignment issues in the microsoft/mu_tiano_plus and tianocore/edk2 repositories. Focused on improving the reliability and security of XDR certificate processing, implemented and validated 4-byte alignment fixes within FmpDevicePkg components. This involved correcting offset calculations and ensuring buffer logic aligned with actual data lengths, which reduced boot-time risks and prevented data access errors. Demonstrated expertise in embedded systems and firmware development, primarily using C, while managing upstream-friendly patches with clear traceability. The work emphasized cross-repository consistency, resulting in a more reliable certificate pipeline without introducing new features during the development period.
