PROFILE
Chernenko Vitaliy
Over a two-month period, contributed backend features to the GreenCity and GreenCityUser repositories, focusing on Java and Spring Boot. Developed an Environment Variables Retrieval API for GreenCity, enabling programmatic access to environment configuration through a new REST endpoint, with supporting DTOs, service logic, and comprehensive unit tests. In GreenCityUser, implemented robust error management for WebClient interactions with external services, introducing custom exceptions and handlers to distinguish client and server errors, improving reliability and observability. Refactored code for maintainability, enhanced test coverage to meet SonarQube standards, and ensured clear error messaging, emphasizing code quality and graceful degradation in failure scenarios.

Jun 1, 2025June 2025 summary for ita-social-projects/GreenCityUser: Implemented robust WebClient error handling for external service calls, introducing GreenCityServiceException and a dedicated CustomExceptionHandler to differentiate client vs server errors and enable graceful degradation. Added GreenCityRemoteWebClientConfig error population logic and GREENCITY_APP_UNAVAILABLE messaging. Refactored WebClient exception handling for maintainability and code quality (formatting and linting). These changes improve reliability, observability, and user experience when external services are unavailable.
