In April 2025, Kazakov enhanced the Tiles API deployment within the 2gis/on-premise-helm-charts repository, focusing on reliability and security. He upgraded the deployment to version 4.69.0 and introduced a readiness probe using Helm and Kubernetes, ensuring pods were healthy before receiving traffic and reducing startup failures. Kazakov also implemented granular API key management by separating authentication tokens for raster and vector data, which improved access control. All changes were documented and default proxy configurations were updated in YAML, supporting safer rollouts. The work demonstrated depth in configuration management and DevOps, addressing both operational stability and security requirements.
