Over a two-month period, Taras Fedorenko enhanced the GreenCityMVP21 repository by delivering seven new backend features focused on API reliability and maintainability. He improved the Eco-News and Language APIs using Java and Spring Boot, introducing explicit error handling, refining DTO validation, and updating API documentation to reflect current behaviors. His work included comprehensive unit testing with JUnit and Mockito, as well as refactoring mapping layers for better data integrity. By standardizing error responses and cleaning obsolete status codes, Taras reduced client-side confusion and troubleshooting time, resulting in a more robust, developer-friendly API that supports faster feature delivery and onboarding.
