Güneş Akkaya contributed to the afet-yonetim-sistemi/ays-be backend by delivering targeted improvements in error handling and data validation over a two-month period. Using Java and Spring Boot, Güneş standardized system-wide error responses by updating conflict error messaging and refining the global exception handler, which improved operational consistency and reduced user confusion. Additionally, Güneş refactored Turkish phone number validation, centralizing logic to enforce country code and length requirements, thereby enhancing data quality and input reliability across endpoints. The work demonstrated a focus on maintainability, robust API design, and comprehensive unit testing, resulting in clearer system behavior and reduced support overhead.

March 2025 (2025-03): Delivered a targeted validation refactor for Turkish phone numbers in afet-yonetim-sistemi/ays-be. The updates enforce Turkish formats by requiring country code '90' and a 10-digit local number, and by updating the maximum length for line numbers across endpoints. Centralized validation improves data quality, reduces invalid inputs, and enhances cross-service consistency. The change was implemented with traceable commits and aligns with AYS-644.
