Worked on embedded firmware and build systems, focusing on reliability and maintainability across acidanthera/audk and NVIDIA/edk2-platforms repositories. Addressed build errors and interrupt handling by refining low-level C code, such as resolving duplicate symbol definitions and correcting interrupt configuration for accurate system behavior. Improved code maintainability by simplifying function signatures and updating reviewer information to streamline code review processes. In NVIDIA/edk2-platforms, removed unused dependencies and fixed toolchain configuration issues, resulting in a cleaner build process and reduced maintenance risk. Demonstrated expertise in firmware development, memory management, and UEFI development, consistently delivering targeted improvements within a short timeframe.
