Professional Summary

I am a DevOps / Platform Engineer and Red Hat Certified Architect (Level IV) with over seven years of experience managing enterprise infrastructure and production operations.

A substantial part of my work has been in virtualisation and storage: configuring and maintaining VMware vCenter/ESXi and highly available Proxmox clusters, integrated with enterprise SAN/NAS platforms including NetApp and IBM storage. I have operated these systems day-to-day — provisioning, capacity planning, performance tuning, and lifecycle maintenance.

I am equally engaged in critical system troubleshooting, restoring service under production pressure, and supporting data-centre migration and application relocation programmes. Alongside this, I administer Kubernetes/OpenShift platforms and uphold PCI DSS-aligned security practices for mission-critical workloads.
