Worked on release engineering and deployment readiness for RStudio Workbench, focusing on the rstudio/rstudio-docker-products and rstudio/helm repositories. Delivered two major version upgrades by updating Dockerfiles, configuration files, and Helm charts, ensuring customers could deploy the latest releases smoothly. Improved test reliability by extending Quarto check timeouts in goss, reducing flaky failures and supporting stable CI/CD pipelines. Used YAML, Shell, and Dockerfile to manage build systems, containerization, and configuration. Enhanced release documentation and artifact consistency across repositories, streamlining upgrade paths and reducing release risk. The work emphasized automation, cross-repo alignment, and robust DevOps practices to support ongoing deployments.
