Worked on enhancing the CityLens deployment process within the 2gis/on-premise-helm-charts repository, focusing on Kubernetes and Helm to streamline on-premise platform delivery. Developed and released version 2.2.0 of the CityLens Helm chart, introducing new environment variables and configuration parameters such as catalog API key support, SSO signup URLs, and feature flag integration. Optimized Nginx configuration and deployment settings to improve reliability and stability, with an emphasis on infrastructure as code principles. The work prioritized scalability, security readiness, and deployment consistency, addressing operational requirements for on-premise environments without focusing on bug fixes during this period.
