During December 2024, Sara Das worked on enhancing build reliability and developer onboarding for Bazel-based SwiftSyntax projects. In the grpc/bazel-central-registry repository, she updated SwiftSyntax dependencies to version 600.0.1, introduced versioned module configuration with MODULE.bazel, and added presubmit.yml to streamline build target verification. For swiftlang/swift-syntax, she improved Bazel integration documentation by providing clear Bzlmod and WORKSPACE examples, clarifying integration paths for developers. Her work focused on Bazel, dependency management, and documentation, addressing configuration hygiene and reducing onboarding friction. While no bugs were fixed, the contributions demonstrated depth in build tooling and process improvement for Swift and Bazel environments.
