Worked on the immich-app/immich repository to address asset duplication issues in the Album View and Remote Timeline. Implemented a checksum-based deduplication fix using Dart and SQL, introducing a correlated subquery that selects unique local assets by checksum. This approach ensured that identical photos appearing in multiple device albums were represented only once, reducing timeline clutter and improving data consistency across devices. Focused on mobile development with Flutter and database management, the work enhanced user experience by streamlining asset representation. Collaborated effectively with other contributors, demonstrating a methodical approach to bug fixing and cross-team problem solving within a mobile application context.
