Worked on the GreenCityMVP21 repository to deliver seven new backend features over two months, focusing on enhancing the Eco-News API, Language API, and rating statistics modules. Applied Java, Spring Boot, and JPA/Hibernate to implement explicit error handling, strengthen DTO validation, and refactor mapping layers for improved data integrity and maintainability. Expanded unit test coverage using JUnit and Mockito, ensuring robust validation and error responses across endpoints. Updated API documentation to reflect current behaviors and removed deprecated fields, resulting in clearer client interactions and streamlined onboarding. The work emphasized reliable API design, consistent error handling, and maintainable backend architecture.
