During June 2025, Tommy Li modernized the continuous integration workflow for the ClickHouse/yet-another-cloudwatch-exporter repository. He reengineered the CI pipeline using GitHub Actions and YAML to publish build artifacts directly to the GitHub Container Registry under the ClickHouse organization, replacing previous dependencies on Docker Hub and Quay.io. By refactoring publish jobs to rely on event names and references, Tommy streamlined the logic and reduced unnecessary complexity. He also implemented GITHUB_TOKEN authentication to enhance security and access control. This work laid the foundation for more automated and secure release processes, demonstrating focused expertise in CI/CD and workflow automation.
