Developed a robust RetryExecutor for the fungover/breeze repository, introducing configurable retry logic with exponential backoff to address transient failures in Java-based systems. The implementation focused on object-oriented design and exception handling, allowing seamless integration with existing operation flows and supporting custom failure handling. Comprehensive unit tests were created to validate successful executions, retry sequences, and scenarios where retries are exhausted, ensuring reliability and maintainability. This work enhanced system stability by reducing the need for manual intervention during temporary outages. The approach demonstrated strong skills in Java, design patterns, and test-driven development, aligning with software engineering best practices.
