Worked on expanding interoperability testing coverage for new grpc-java versions within the Shopify/grpc repository. Focused on updating the client interoperation matrix to include grpc-java versions 1.71.0 and 1.72.0, enabling comprehensive interop tests and supporting smoother upgrade paths for downstream users. Utilized Python for development and testing, with an emphasis on CI/CD workflows to ensure robust release readiness. The work centered on feature delivery and maintenance of the testing matrix, improving test coverage across Java versions and reducing integration risks. No major bugs were reported, reflecting a focus on proactive quality assurance and forward-looking compatibility planning for Java interop scenarios.
