This period also established a robust test coverage for the new domain and application layers, while introducing new features for external routing and public tracking interfaces.

2017–2023 · Spring Boot 3.0 migration and REST API modernization

The codebase was modernized by migrating to Spring Boot 3.0, replacing XML configuration with Java-based setup and adopting Thymeleaf for the web interface. A public REST API for cargo tracking was introduced alongside comprehensive acceptance and integration tests to ensure reliability.
