Worked on the google/adk-java repository to deliver the ADK Java library version 0.3.0, focusing on enhancing integration and configuration capabilities. Developed new features including toolset integration, configurable CORS support, and improved agent loading mechanisms, all aimed at increasing library stability and simplifying downstream adoption. Managed the full release process, including version tagging and changelog updates, to ensure clear communication of changes. Updated documentation to provide comprehensive guidance on new features and configuration options. Utilized Java for core development, applied build automation techniques, and demonstrated release management skills to streamline delivery and support maintainability for future adopters.
