Key Strengths

• Owned and administered scaled IBM Power/AIX environments (25–30 AIX LPARs) with HMC and dual VIOS
• Live DLPAR capacity tuning using performance data (reduced CPU saturation from >90% to ~60% without downtime)
• Production PowerHA incident response and recovery validation (resource group move, VG varyon, service IP reassignment, DB restart verification)
• Strong RCA discipline (identified firmware instability bug; implemented staged firmware upgrade and improved validation checklists)
• End-to-end AIX migration/cutover execution (Power7 to Power9, OS upgrade, storage refresh) with runbook, rollback planning, and post-cutover stabilization
• Built secure, repeatable CI/CD with Azure DevOps + Terraform + Kubernetes/Helm (Key Vault secrets, approvals, versioning, rollback/blue-green)
• Terraform state/drift management in AWS (scheduled plan checks, locking/versioning, CloudTrail + IAM controls, import to resolve drift)
