Worked on the googleapis/java-spanner-cassandra repository, delivering sixteen features over five months focused on backend development, integration, and performance. Enhanced the Spanner Cassandra adapter by expanding integration tests, optimizing driver performance, and introducing observability with OpenTelemetry. Improved protocol handling and client compatibility through a custom server frame codec, while refactoring configuration with AdapterOptions for maintainability. Strengthened CI/CD pipelines using GitHub Actions and Docker, and documented metrics, CQLSH integration, and deployment guidance. Leveraged Java, SQL, and gRPC to implement robust error handling, efficient network programming, and codebase quality improvements, supporting multi-database workloads and enabling more reliable, scalable deployments for users.
