Developed and delivered a data-safe asset deletion workflow for the lollipopkit/immich mobile app, focusing on backup-aware deletion and accurate asset count reporting. The work involved implementing frontend logic and UI updates using Dart and Flutter to ensure that only assets verified as backed up could be deleted, thereby reducing the risk of data loss and improving data integrity. Collaborated closely with backend and QA teams to validate backup state semantics and align the user interface with backend state. This feature enhanced the reliability of the asset lifecycle, strengthened user trust, and demonstrated strong cross-team communication and code quality practices.
