Mikolaj Matuszny focused on enhancing CI/CD reliability and efficiency across several SonarSource repositories, including sonarlint-core, sonarlint-eclipse, SonarJS, and cookiecutter-sonar. He stabilized build pipelines by pinning tool versions and updating workflows using GitHub Actions and Maven, which reduced failures from dynamic dependencies and improved reproducibility. In sonarlint-eclipse, he implemented artifact code signing, streamlining Maven configurations to ensure secure, verifiable releases. For SonarJS, he optimized runner sizes to lower CI costs without sacrificing performance. His work also included workflow caching enhancements and license data updates in cookiecutter-sonar, leveraging YAML and XML to support maintainable, compliant, and cost-effective development cycles.
