During December 2025, Salmasamy focused on improving the robustness of Bazel’s module graph generation in the bazelbuild/bazel repository. Addressing a Null Pointer Exception triggered by the extension filter, Salmasamy implemented backend logic in Java to ensure the graph generation process remains stable under constrained conditions. The solution included comprehensive regression testing to validate the fix and prevent future issues, demonstrating a test-driven approach. By collaborating across teams and triaging the issue, Salmasamy enhanced the reliability of Bazel for users leveraging extension filters. This work showcased skills in Java, backend development, and testing, contributing to Bazel’s stable build guarantees.
