Nazik Vaver contributed to the GreenCity and GreenCityUser repositories by building and refining backend features focused on user engagement, authentication, and notification management. She implemented robust sorting and pagination for achievements, modernized Facebook authentication using Java Spring WebClient, and enhanced REST API observability with transaction-aware logging. Her work included unifying notification retrieval logic, improving filtering accuracy, and addressing code quality through refactoring and expanded test coverage. Using Java, Spring Boot, and SQL, Nazik delivered maintainable, testable solutions that improved reliability and user experience. Her engineering demonstrated depth in backend API design, error handling, and scalable data management across microservices.

May 2025 — GreenCity (ita-social-projects/GreenCity): Delivered backend enhancements to notification filtering and viewing, plus code quality improvements. Key features delivered include unified notification retrieval and viewing enhancements with correct handling of the 'viewed' parameter across project types, plus helper methods and pagination support to improve reliability, scalability, and maintainability of notification filtering. Major bugs fixed include ensuring notifications are not erroneously shown when the 'viewed' parameter is false and addressing a Sonar-related issue for code quality. Overall impact: improved user experience with accurate notification display, more reliable cross-project type filtering, and reduced technical debt, enabling faster future feature work. Technologies/skills demonstrated: backend API design and implementation (e.g., Ruby/Rails), pagination, helper utilities for filtering, cross-project context handling, and code quality improvements (SonarQube), with an emphasis on testability and maintainability.
