During October 2025, Mosses contributed to the jellyfin/jellyfin repository by addressing a backend issue related to data accuracy and pagination. He implemented a fix in C# that corrected the total record count calculation when grouping filters were applied in database queries. This adjustment ensured that the reported totals accurately reflected the actual number of items after grouping, which is essential for reliable pagination and precise data representation in listing views. Mosses focused on backend development and database management, demonstrating a solid understanding of query logic and data integrity. His work improved the reliability of grouped data presentation within the project.
