Key Strengths

• Owned large-scale IBM Power/AIX footprint (150+ LPARs on AIX 7.x)
• End-to-end LPAR provisioning via HMC (CPU/memory/storage allocation and VIOS capacity checks)
• Outage troubleshooting restoring LPAR storage connectivity by identifying VIOS network misconfiguration via vHMC logs
• PowerHA incident recovery: resolved routing misconfiguration preventing failover after network switch failure and restored services
• Planned and executed AIX 6.x to 7.x migration with discovery, dry runs, backups, and rollback planning
• Built and secured Jenkins CI/CD deploying GitHub-sourced web app to AKS (secrets management, approval gates, Docker image versioning)
• Diagnosed and fixed CI/CD failure caused by missing Docker dependency; added validation checks
• Implemented Terraform IaC on AWS with modular structure, S3 remote state + DynamoDB locking, workspaces per environment, and drift checks
