Yifan Yuan
Contributed to the PhotonLibOS repository by developing and integrating core filesystem and caching features using C++ and CMake. Delivered a new cache module based on the Open CAS Framework, enhancing I/O performance and modularity while maintaining build reliability across distributions. Improved the ExtFileSystem by exposing underlying image files for better debugging and integration testing, and addressed crash scenarios by refining error handling. Refactored the build system and directory structure to align with evolving filesystem modules, reducing maintenance overhead and supporting future enhancements. Focused on low-level programming, build system configuration, and robust file system management to ensure stability and scalability.
