Worked on firmware and hardware compatibility for Dasharo/edk2 and Dasharo/coreboot, focusing on embedded systems and low-level programming in C. Delivered a targeted fix to stabilize CPU exception handling by modifying UefiCpuPkg to ignore DEBUG interrupts, which improved debugging reliability and established a stable baseline for further development. Later, implemented DDR5 SPD data access by adding SPD5 hub read support in soc/common/smbus, enabling DDR5 memory module compatibility and laying the groundwork for future features. The work emphasized system programming, hardware interfacing, and memory management, with clear, auditable changes that enhanced both debugging workflows and hardware support in these repositories.
