Worked on the scheduleonce/once-ui repository to deliver a comprehensive CI/CD runtime upgrade, focusing on enhancing security, compatibility, and build performance. The project involved updating the Dockerfile base image to node:22.16.0-alpine3.22 and revising the pullrequest.yaml configuration to ensure all build, formatting, linting, and testing steps consistently used Node.js 22.16.0. Leveraging skills in CI/CD, containerization, and DevOps, the work improved build reliability and streamlined future upgrades. By standardizing the runtime environment with Dockerfile and yaml, the upgrade addressed stability and security concerns, laying a foundation for more robust and maintainable development pipelines moving forward.
