Ajan Zhong focused on improving firmware stability and cross-platform compatibility in the acidanthera/audk and NVIDIA/edk2-platforms repositories. Over four months, Ajan addressed critical bugs in UEFI and ACPI handling, such as fixing unaligned 64-bit data access in ARM64 payload parsers and aligning framebuffer parameters for better OS support. Using C and INF, Ajan enhanced build system reliability by resolving StackCheckLib dependencies and updated library paths to ensure consistent platform integration. The work demonstrated depth in low-level programming, device tree management, and build configuration, resulting in more robust boot processes and streamlined maintenance for embedded systems and UEFI firmware projects.

April 2025 (NVIDIA/edk2-platforms) — Key features delivered: Relocated the ArmMmuLib library path from ArmPkg to UefiCpuPkg in EDK2 and updated platform DSC references to ensure correct library resolution across affected platforms. Major bugs fixed: Ensured consistent library resolution across platforms, preventing build-time reference errors and potential runtime issues. Overall impact and accomplishments: Improved build stability and cross-platform compatibility for EDK2 firmware, enabling smoother integration and reduced maintenance overhead for platform DSC configurations. Technologies/skills demonstrated: EDK2/UEFI development, ArmPkg/UefiCpuPkg integration, DSC-based build configuration, library path management, cross-repo changes, and disciplined version control.

February 2025: Build stability improvement for AUDK through a critical StackCheckLib dependency fix that restored FIT build success. No new features shipped; focus was on resolving a cross-module dependency after a StackCheckLib reorganization and ensuring CI/build reliability for downstream packaging.
