Andrey Malko worked on the 2gis/on-premise-helm-charts repository, focusing on improving deployment reliability and version alignment for the Pro UI service. He upgraded the Pro UI image tag and synchronized the Helm chart’s appVersion and image.tag to ensure consistent rollouts across environments. Using Helm, Kubernetes, and YAML, Andrey also updated the Breaking-Changes documentation to clarify version implications and configuration validation requirements, helping users avoid misconfigurations and reduce downtime during upgrades. His work provided a clearer migration path for on-premise deployments, demonstrating a methodical approach to DevOps practices and thorough attention to deployment and documentation quality over two months.
