Worked on CI/CD pipeline modernization for thebrowsercompany/swift-build, focusing on improving security, compatibility, and maintainability. Updated the pipeline to use the latest Azure Windows VM images, ensuring up-to-date environments and reducing potential vulnerabilities. Streamlined configuration management by removing outdated cirun-win11 labels, which simplified runner setup and reduced ongoing maintenance. Leveraged YAML for pipeline configuration and applied DevOps best practices to enhance build reliability and speed. All changes were documented with clear commit references, supporting traceability and transparency. This work resulted in a more robust and efficient CI/CD process, lowering the support burden for future development and operations teams.
