Worked on the openedx/enterprise-access repository to implement automatic expiration of linked credit requests when a content assignment expires. Leveraging Python and Django for backend and API development, the solution updated the expire_assignment logic to mark related credit requests as EXPIRED and persist these changes in the database. Additionally, the notification system was refined so that expiration emails are only sent if no associated credit request expired, improving notification accuracy. This feature enhanced lifecycle management and data integrity, reducing manual intervention and supporting compliance requirements. The work demonstrated a focused approach to backend process automation and robust state management within the system.
