Janhavi Sahasrabuddhe focused on stabilizing automated testing for the DataDog/dd-trace-java repository by addressing flakiness in the HTTP test suite. She implemented a targeted fix in Java and Groovy to ensure HttpServerTest properly closed response bodies, resolving HTTP/2 flow control issues that caused intermittent test failures in CI environments. Her work improved the reliability and speed of feedback for backend development teams by reducing flaky exceptions and strengthening test coverage for HTTP server behavior. Janhavi collaborated with other contributors, integrating her changes through multi-author commits and branch workflows, and demonstrated expertise in HTTP protocols, backend testing, and Git-based development.
