Mark Tucker

Worked on the rstudio/helm repository to deliver four feature releases of the Posit Chronicle Helm charts, focusing on deployment reliability, resource governance, and release automation. Leveraged Helm, Kubernetes, and YAML to upgrade the Chronicle agent, implement resource limit configurations, and synchronize versioning across posit-chronicle, rstudio-connect, and rstudio-workbench charts. Coordinated cross-repository changes and updated documentation to ensure compatibility and streamlined onboarding. Integrated releases with CI/CD pipelines using GitHub Actions, enhancing deployment consistency and readiness for new Chronicle capabilities. The work emphasized maintainable chart versioning, explicit resource management, and comprehensive documentation, supporting stable, repeatable rollouts across diverse deployment environments.
