In February 2026, S. Sunbul developed an optimization for the gofiber/fiber repository, focusing on exponential backoff timing in backend request retries. Sunbul improved the retry logic by removing an unnecessary sleep after the final retry attempt, directly reducing wasted wait time and enhancing request latency in error-prone scenarios. To ensure correctness, Sunbul added targeted tests validating that no sleep occurs after the last retry, thereby increasing reliability and maintainability of the codebase. This work leveraged Go and backend development skills, with careful attention to error handling and testing, demonstrating a thoughtful approach to performance and correctness in production systems.
