Worked on backend development for the ynput/ayon-core repository, focusing on improving CollectHierarchy attribute handling for new shots and first-time folder creation. Using Python, implemented a clear separation of logic to distinguish between new and existing shots, introducing a shot_exists flag to clarify update behavior. Added checks to ensure attributes are correctly created or updated when folders are published for the first time, addressing issues with empty attributes and manual corrections. The solution involved refining conditional logic and enforcing folder-creation checks, which enhanced data integrity and reliability in automated workflows. This work demonstrates depth in backend systems and workflow automation.
