Jerry Shao developed core data catalog, model management, and job execution systems for the apache/gravitino repository, focusing on scalable backend architecture and robust API design. He implemented RESTful APIs and multi-language client libraries in Java and Python, enabling seamless integration and lifecycle management for models and jobs. Jerry refactored legacy Hadoop catalog code to a Fileset-based approach, modernizing data source handling and improving release readiness. His work included persistent data modeling, event-driven observability, and automated build and release pipelines using Gradle and CI/CD. The solutions delivered maintainable, extensible infrastructure, with careful attention to governance, dependency management, and test automation.

October 2025: Delivered major enhancements to the Gravitino job-template lifecycle with REST and client APIs, introduced comprehensive event-driven observability, and stabilized builds through dependency cleanup. Administrative updates to contributor records completed. These changes enable faster, auditable template changes with lower build risk and clearer governance.

September 2025 (apache/gravitino) focused on tightening release readiness, stabilizing the build, expanding extensibility, and improving client reliability. Key features delivered include release process automation and versioning for the 1.0.0 release and preparation of the next development version, local Spark job execution support via spark-submit, and Java/Python interfaces to alter job templates (with unit tests). CI stability improvements reduced flaky runs by increasing timeouts for Python and Ranger integration tests. Documentation quality improvements and OpenAPI wording updates were completed. Python 3.8 support was deprecated in the Python client to streamline CI and dependencies.
