Key Strengths

  • Troubleshoots IBM Power LPAR/DLPAR issues via RMC and network-path validation (HMC↔LPAR ping, VLAN tagging, firewall/port checks)
  • PowerHA/HACMP cluster operations and planned failover execution with pre-checks and post-failover stability verification
  • Structured migration/cutover governance (change requests, stakeholder comms, change committee approvals, risk and rollback planning)
  • AIX performance triage using core tooling across CPU/memory/disk/network (lparstat, vmstat, iostat, netstat, nmon, topas)
  • CI/CD implementation with quality gates and container build flow (Maven, Docker, SonarQube) plus repeatable deployments (Helm/Kubernetes)
  • IaC discipline with drift controls (Git as source of truth, no console fixes, review/approval for high-risk changes, controlled apply windows)
