Worked on the 2gis/on-premise-helm-charts repository to deliver a feature enabling key data import migrations for on-premise Helm deployments. Introduced a migration flag to the keys data import process and updated the backend image tag, allowing for a controlled and safer migration flow during upgrades. Leveraged DevOps practices and Kubernetes expertise, with YAML as the primary language for deployment configuration. The changes focused on improving data integrity and deployment reliability, ensuring that on-premise environments could adopt new migration capabilities with minimal risk. No bugs were reported during this period, reflecting a focused and stable engineering effort on feature delivery.
