Worked on code hygiene and API maintenance within the githubnext/discovery-agent__apache__flink repository, focusing on improving maintainability and clarity in the Java codebase. Delivered a targeted refactor by removing an unused FlinkException from the JobMasterServiceLeadershipRunner method signature, aligning the API with actual usage and reducing the risk of confusion or signature mismatches in future development. This change simplified the interface and made the codebase easier to understand for other contributors. Leveraged Java development and refactoring skills to ensure the update supported smoother future changes, with an emphasis on clean, maintainable code and reduced technical debt in the integration layer.
