Worked on stabilizing the Multifd migration path in the espressif/qemu repository, focusing on improving build reliability for system-level code. Addressed a critical compile-time issue by correcting the inline usage of page_size and related constants after their inlining, which resolved a persistent compilation error in the Multifd Migration Module. This targeted fix reduced the risk of CI failures and enabled smoother integration of migration code. Demonstrated strong debugging and code review skills while working primarily in C, with an emphasis on kernel development and system programming. The work contributed to more robust build processes and enhanced maintainability of the migration module.
