Worked on the canonical/mir repository to enhance the stability and reliability of its graphics subsystem, focusing on C++ development with X11 and multithreading. Addressed memory safety by refactoring XCB resource management, introducing scoped smart pointers to prevent leaks, and ensuring proper destruction of XCB windows. Improved thread-safe error handling by replacing strerror with a safer alternative, mir::errno_to_cstr, and enforced POSIX compliance in error utilities. Prioritized robust error and resource management over new feature delivery, with all work aimed at reducing runtime risk in multi-threaded and long-running deployments. Emphasized maintainability and correctness through targeted debugging and code cleanup.
