Handle containerized deployments in Ericsson CaaS / CCD-based environments using Helm/K8s tools.

Work with backup/restore tools for cluster and DB safety before upgrade initiation.

Proactively identify and troubleshoot upgrade-related issues across nodes, clusters, or interfaces.

Provide logs and RCA documentation for post-upgrade issues (connectivity, schema migration, data sync).

Fine-tune system parameters and cluster configurations for optimized post-upgrade performance.

Prepare and review MOPs (Method of Procedure), CRs (Change Requests), and deployment plans.

Maintain technical documentation, design changes, and interface control documents.

Support compliance with security and audit controls during the upgrade.
