Worked on the afet-yonetim-sistemi/ays-be repository, focusing on backend development and system reliability over a two-month period. Delivered features such as centralized Turkish phone number validation, enforcing country code and length requirements to improve data quality and consistency across endpoints. Enhanced error handling by standardizing conflict error messaging and updating the global exception handler, which reduced ambiguity for users and support teams. Updated system-generated email addresses to a dedicated no-reply address, improving deliverability and clarity. Utilized Java, Spring Boot, and unit testing to ensure robust implementation, with an emphasis on maintainability, validation, and clear operational communication throughout the codebase.
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.
