Filiz Helvacı contributed to the afet-yonetim-sistemi/ays-be repository by delivering five backend features over four months, focusing on data validation, API simplification, and email templating. She implemented city and name validation mechanisms using Java, Spring Framework, and JUnit, ensuring data integrity for user registration and filtering workflows. Her work included refactoring token management to streamline API responses and reduce unnecessary state exposure, as well as updating password email templates for improved branding. Filiz’s engineering approach emphasized maintainability and test coverage, with targeted refactors and annotation-driven validation that reduced backend errors and supported future extensibility across the application.
February 2026: Focused on strengthening user data validation and reducing registration/update errors through new validation primitives and targeted refactoring. Delivered a stricter name validation workflow and migrated city name validation to a dedicated form object, with updated tests to ensure regression coverage. These changes improve data integrity, reduce backend validation failures, and set groundwork for consistent form validation across the application.

January 2026 (2026-01): Focused on strengthening data integrity for city-related user data in afet-yonetim-sistemi/ays-be. Implemented two city name validation mechanisms (CityForm for registration and CityFilter for user filters), each backed by dedicated validators and tests, ensuring only valid city names are accepted across entry points and filters. These changes lay groundwork for reliable city-based analytics and improved UX when users enter location data.

December 2024 monthly summary for afet-yonetim-sistemi/ays-be: Token Management Simplification delivered via a targeted refactor to remove the accessTokenExpiresAt field from AysToken and AysTokenResponse. This reduces exposure of explicit expiration timestamps, streamlines token usage for downstream services, and improves maintainability by removing unnecessary state. The change lowers risk surface, simplifies future development, and enhances security hygiene without introducing user-visible behavior changes. Commit-based traceability is preserved for auditability.
