Worked on the pygame-community/pygame-ce repository to refactor memory management across more than 20 C modules, focusing on rendering and input stability. Applied a cross-module transition from Py_INCREF to Py_NewRef, improving reference counting efficiency and correctness in subsystems such as bufferproxy, camera, and freetype. Addressed known PyObject lifecycle issues and reduced unnecessary typecasts, which helped streamline memory handling and reduce churn in performance-critical code paths. Enhanced maintainability by updating documentation and establishing consistent reference-counting guidelines. Utilized C programming, memory management, and software optimization skills to deliver measurable performance improvements and more robust memory handling throughout the codebase.
