Worked on the listenbrainz-server repository to deliver the Jewelcase Offline Music Player Integration, expanding offline playback support for iOS users. Focused on front end development using React and TypeScript, the work involved adding Jewelcase to the AddData list and relocating its link to a more prominent, mobile-friendly position to enhance accessibility and app discovery. Commits were concise and well-scoped, supporting efficient code review and rollback. No major bugs were reported during this period, and the changes improved the user experience for mobile users seeking offline playback options, demonstrating a methodical approach to incremental feature delivery and interface refinement.
