During the month, contributed to the umbraco/Umbraco-CMS repository by addressing a concurrency issue in media operations. Focused on backend development and resource management using C#, the work involved correcting MediaService resource locking by switching the read lock from ContentTree to MediaTree for paginated media retrieval. This technical adjustment resolved a bug that previously risked stale reads and data inconsistencies, especially under high-traffic conditions. The change improved data integrity and reliability for both editors and API consumers interacting with media endpoints. The solution demonstrated a targeted approach to API development, enhancing the stability of media workflows within the Umbraco CMS platform.
