Worked on optimizing bulk file deletion performance in the catalyst/moodle-tool_objectfs repository, focusing on reducing latency and improving scalability for Moodle administrative tasks. The approach involved implementing an early check in the PHP back end to skip unnecessary remote server lookups during bulk deletions, thereby minimizing external HTTP requests when immediate external deletion was not configured. This change preserved the correctness of orphaned file cleanup by ensuring essential cleanup paths remained intact. The work was documented and validated through traceable commits, resulting in faster bulk deletions and more efficient remote filestore interactions, leveraging PHP and back end development expertise throughout the process.
