During January 2026, Erfan Momeni co-developed a context-based expiration feature for the Rate Limiter middleware in the gofiber/fiber repository. This enhancement introduced an ExpirationFunc, allowing expiration times to be dynamically computed per request based on context, which improved both security and user experience for sensitive endpoints such as login. Erfan’s work focused on backend development and middleware design using Go, emphasizing robust integration and validation within the existing rate-limiting framework. The implementation leveraged context propagation and dynamic function hooks, ensuring minimal latency and no regression in performance, and demonstrated careful attention to code quality through collaborative review and testing.
