During their two-month contribution to the google/heir repository, Stubley focused on enhancing both demonstration reliability and test coverage for MLIR-based compiler workflows. They corrected the demo script to reference the accurate 'secret-to-cggi' conversion pass, ensuring that stakeholder presentations reflected actual product behavior and reducing confusion during demos. In addition, Stubley developed a new MLIR test file to validate RLWE operation syntax, covering addition, subtraction, multiplication, and negation, and addressed lint issues to improve maintainability. Their work leveraged skills in compiler development, domain-specific languages, and scripting, demonstrating careful attention to code accuracy and robust testing practices throughout the project.
