Worked on the Hirschgarten repository to improve the stability and reliability of its Java build pipeline. Addressed a recurring issue in the Bazel build system by adding a missing load statement for java_common within the java_info.bzl.template file, which resolved import errors and reduced flakiness in Java information processing. Focused on enhancing continuous integration outcomes by ensuring that Bazel templates imported dependencies correctly, leading to more predictable and stable CI results. Utilized Starlark and Bazel to implement these changes, concentrating on core build system improvements rather than feature development, and contributed to a more robust engineering workflow for the project.
