• Plan and execute migration of clusters and workloads from on-prem (Cloudera/Confluent) to AWS MSK
• Design cutover strategies with minimal downtime and no data loss
• Build and maintain Kafka/MSK infrastructure using Terraform
• Manage automated deployments and configuration through GitLab CI/CD pipelines
