Riya Mehta worked on simplifying the build system for the grpc-java repository by standardizing the naming of the S2A credential library. She renamed the s2av2_credentials target to s2a in the BUILD.bazel configuration, focusing on improving maintainability and consistency across the codebase without altering runtime behavior. This adjustment streamlines developer onboarding and reduces confusion around build targets. Riya applied her skills in build system configuration and Java to ensure the change was traceable and auditable, referencing commit 29dd9bad3f19f948a8d157449b022b96b5b8d6b6. The work addressed technical debt and enhanced the repository’s long-term maintainability.
