PROFILE

Dol

Worked on core subsystem improvements for DragonOS-Community/DragonOS, focusing on stability, POSIX compatibility, and maintainability. Modernized the syscall API by migrating to a TrapFrame-based context and unifying syscall handling through a dedicated Syscall trait, while refactoring process-related syscalls into modular components and removing legacy code. Addressed file system correctness by fixing the getdents implementation in the virtual file system to conform to POSIX directory listing semantics, introducing buffered traversal and accurate directory entry population. Utilized Rust for system programming, emphasizing kernel development, operating system internals, and refactoring to deliver a more robust and maintainable codebase.
