Mikolaj worked on mesosphere/kommander-applications and mesosphere/charts, focusing on release engineering, configuration management, and deployment stability. Over eight months, he migrated container image publishing to GitHub Container Registry, upgraded Helm APIs, and standardized versioning to streamline release workflows. Using Go, YAML, and Helm, Mikolaj improved CI/CD automation, enhanced Git service compatibility, and maintained Kubernetes manifests to reduce upgrade friction and configuration drift. He addressed integration issues after version upgrades, fixed container image references following GitHub organization changes, and improved test reliability by aligning test suites with evolving APIs. His work demonstrated depth in DevOps and release process automation.
