Worked on the 2gis/on-premise-helm-charts repository to deliver an upgrade of the keys-ui component to version 0.10.3, ensuring all Helm chart configurations referenced the latest release. The approach involved updating YAML manifests across multiple files, validating configurations to maintain deployment consistency, and documenting the upgrade and rollback process for future maintainers. By establishing a repeatable upgrade pattern, the work reduced the risk of outdated UI deployments and improved operational clarity for chart operators. The project demonstrated skills in DevOps practices, Helm chart management, and YAML configuration, focusing on deployment stability, version traceability, and streamlined upgrade workflows within the repository.
