Ekaterina Kitova focused on improving the stability and reliability of on-premise Helm charts in the 2gis/on-premise-helm-charts repository. She addressed a critical deployment issue by fixing incorrect references to access and secret keys in the license service’s secret.yaml, ensuring that correct persistence values are used during deployment. This change, implemented using YAML and Helm within a DevOps workflow, resolved potential S3 access issues and reduced deployment-time failures for the license service. While the scope of work was targeted, her contribution demonstrated careful attention to deployment configuration details, directly enhancing the reliability of the license service in production environments.
