Developed and integrated a JavaScript CI/CD workflow for the NCAR/musica repository, focusing on automating builds and tests for both the main branch and incoming pull requests. Leveraged GitHub Actions and YAML to configure a Node.js environment, manage dependency installation, and execute build steps, ensuring consistent and reliable test execution. Enhanced project transparency by updating the README with a badge that displays JavaScript test results, providing immediate feedback on code health. This work improved code quality and reduced integration risk for JavaScript contributions, demonstrating proficiency in build automation, CI/CD practices, and collaborative development using modern tooling and configuration languages.
