April 2025 monthly backend summary focused on establishing a robust MySQL-backed persistence layer, validating user data, maturing domain models, and improving repository hygiene. Delivered key features, stabilized data access, and set the foundation for scalable locker and access-code workflows.

This month (2024-11) delivered a comprehensive unit test suite for the PowerMate UserController, establishing robust test coverage for create, list, update, and delete flows, and validating interactions with UserService via Mockito. The work reduces regression risk and supports safer deployments by validating HTTP status codes and response bodies across success and not-found scenarios. No major defects were fixed this month; the emphasis was on quality assurance and maintainability.
