Elias Benbourenane focused on enhancing file system reliability for the Radarr and Sonarr repositories by addressing critical bugs in file size reporting. He improved the GetFileSize functionality to correctly resolve symbolic links, ensuring that disk space calculations reflect the actual size of target files rather than the links themselves. Working primarily in C# and leveraging core library and file system operation skills, Elias aligned utility behavior across both projects to reduce discrepancies and edge-case errors. His targeted bug fixes, linked to explicit commits, contributed to more robust data integrity and streamlined downstream workflows, demonstrating careful attention to detail and maintainability.
