Contributed to the apache/ozone repository over four months, focusing on stabilizing test suites, enhancing UI usability, and improving CI reliability for large-scale deployments. Delivered features such as sticky columns and multi-select search in React-based interfaces, while also implementing automated test suites using Java and Robot Framework to validate object store operations and snapshot defragmentation. Addressed flaky tests and improved build stability through dependency upgrades and refined polling mechanisms, ensuring consistency across high availability scenarios. The work emphasized cross-domain collaboration, integrating backend reliability improvements with frontend enhancements, and prioritized maintainability, test automation, and clear feedback loops to support both developers and end users.
