Worked on the guardian/scala-steward repository to enhance the robustness of SBT module ID parsing for Scala projects. Focused on refining regular expressions to correctly handle trailing comments and whitespace after version numbers, the work addressed potential misparsing issues that could affect dependency resolution. Implemented targeted unit tests, including coverage for block comments, and refactored test code to improve readability and maintainability. Applied consistent code formatting across relevant files, contributing to overall code quality. Leveraged skills in Scala, build tool configuration, and testing to deliver changes that improve CI reliability and ensure accurate module identification for downstream tooling compatibility.
