Worked on stabilizing and enhancing low-level firmware and input handling in the microsoft/mu_plus and microsoft/mu_basecore repositories, focusing on bug fixes that improved device reliability and user experience. Addressed issues such as input method switching between touch and keyboard, keyboard LED state synchronization, and touchscreen HID error handling by refining event handling and initialization logic. Improved firmware update resilience by validating recovery headers and enabling fallback mechanisms in variable store recovery. Leveraged expertise in C, Rust, and UEFI development, applying embedded systems and driver development skills to deliver robust, maintainable solutions that strengthened hardware-software integration and system stability.
May 2025 performance summary for microsoft/mu_basecore: Strengthened FTW recovery robustness in the variable store by validating FtwWorkSpaceHeader and enabling recovery from a spare block. This reduces recovery failures when the primary FTW store is erased or corrupted and improves resilience of firmware update/restore paths. The work was implemented via a cherry-picked patch to MdeModulePkg FaultTolerantWriteDxe with commit 4b640d6c142650824dc8a3dd38ec55597b26d2dd.
