What I built

  1. 01Built a layered Spring Boot API (controller, service and repository) with Spring Data JPA on MySQL.
  2. 02Added request DTOs, a uniform ApiResponse wrapper and global exception handling.
  3. 03Built the Flutter client with a Dio networking layer, swipe-to-delete, completion checkboxes and auto-refreshing lists.
