Over four months, Irfan Evrens developed and enhanced backend features for the afet-yonetim-sistemi/ays-be repository, focusing on scalable institution management, security, and localization. He implemented a multi-tenant institution listing service with filtering and pagination using Java, JPA, and the Spring Framework, improving administrative workflows and user experience. Irfan strengthened access token security by removing sensitive claims and enforcing institution activity checks, aligning with privacy best practices. He also improved deployment traceability and Turkish localization, ensuring clarity for end users. His work demonstrated depth in REST API development, backend architecture, and internationalization, consistently delivering maintainable, business-focused solutions.

In January 2026, focused on strengthening access token security for afet-yonetim-sistemi/ays-be. Implemented privacy improvements by removing userEmailAddress from access token claims and added validation to prevent token creation/renewal for inactive institutions. These changes reduce privacy risk, prevent token misuse, and contribute to privacy/compliance efforts while maintaining system usability. Progress aligns with security best practices and auditability through explicit commit references.

October 2025: Delivered targeted improvements across two repositories, strengthening deployment observability and end-user experience. Implemented build-number exposure via Build Metadata in the AYS BE actuator info endpoint, including config updates and an end-to-end test to verify build numbers are returned. Corrected Turkish localization strings for error and validation messages, improving clarity for Turkish-speaking users. These changes enhance deploy traceability, reduce ambiguity for end users, and expand test coverage with a focus on business value and maintainable code quality.
