Worked on the jellyfin/jellyfin repository to address data accuracy and pagination reliability in listing views. Focused on backend development using C# and database management skills, implementing a fix that corrected total record count calculations after grouping filters were applied in database queries. This adjustment ensured that the reported totals accurately reflected the actual number of items, which is essential for correct pagination and data representation. The work involved analyzing how grouping affected query results and modifying the logic to align totals with grouped data. The contribution improved the integrity of data presentation without introducing new features, emphasizing precise backend problem-solving.
