Key Strengths

• Owned large-scale IBM Power/AIX production environment supporting hundreds of LPARs
• End-to-end performance troubleshooting using AIX/VIOS metrics and DLPAR to remediate CPU pool oversubscription with minimal impact
• Led manual PowerHA failover during disk-latency incident and restored services within SLA
• RCA-driven resiliency improvements (identified failing SAN path; implemented SAN path redundancy and improved monitoring/procedures)
• Led AIX 7.1 to 7.3 migration/cutover with minimal downtime and no data loss
• Built and secured Jenkins CI/CD with Vault-managed secrets, approvals, versioned artifacts, and rollback jobs
• Diagnosed CI/CD deployment failure caused by corrupted Docker image; added integrity checks and improved Jenkins/Kubernetes logging
• Implemented Terraform IaC for Azure with modular design, remote state, plan/review gates, drift checks, and dev-to-prod promotion
