About

Senior infrastructure/platform engineer with deep IBM Power/AIX (Power9, VIOS, HMC, LPAR/DLPAR) and PowerHA production ownership at scale (40 frames / ~300 LPARs), including hands-on outage recovery and performance tuning. Also delivers modern DevOps/IaC capabilities—CI/CD for Kubernetes microservices and Terraform-based multi-account AWS (EKS/VPC/IAM/RDS) with drift detection and safe rollout controls.

Key Strengths

• Owned large-scale IBM Power/AIX estate (40 Power9 frames, ~300 LPARs) across prod/DR/test
• End-to-end incident troubleshooting for DLPAR failure; restored CPU entitlement without reboot/downtime by fixing RMC connectivity
• PowerHA operations and recovery leadership; executed quarterly failover testing and handled real failover with <3 minutes downtime and no transaction loss
• Led AIX 7.1→7.2 migration for ~20 production workloads with <15 minutes downtime per node using structured runbooks, rollback checkpoints, and stakeholder coordination
• Built secure, auditable CI/CD pipelines with secrets management (Key Vault/OIDC/Secrets Manager), approvals, artifact immutability, and blue-green/Helm rollbacks
• Implemented multi-account AWS Terraform platform (EKS/VPC/IAM/RDS/CloudWatch) with versioned modules, remote state locking, drift detection, and gated promotions; reduced provisioning to <20 minutes
