Worked on the jellyfin/jellyfin repository to enhance the reliability of the Schedules Direct API integration by implementing robust error handling and clarifying error codes and messages. Focused on improving maintainability through targeted code cleanup, including renaming internal variables and correcting error code prefixes to better align with product standards. Updated documentation to support these API changes, making onboarding and troubleshooting more straightforward for developers. Utilized C# programming and API development skills to refactor features such as renaming MaxImageDownloads2 to MaxImageDownloadsTrial, reflecting its experimental status. The work addressed integration reliability and reduced future support overhead through clearer error semantics.
