What I'm looking for

I’m looking to deepen my Enterprise DC Operations impact—owning virtualization platforms, leading resilient change and maintenance, and supporting critical HA production environments, with strong focus on VMware and rapidly maturing Proxmox operations.

I’m a Cloud & DC Engineer specialising in Virtualisation with over 6 years of experience in Enterprise IT Infrastructure and Systems Management, currently focused on VMware/Proxmox operations.

With VMware VCP-DCV 2024 and ITIL 4 Foundation certifications, I bring 3+ years of administration experience across VMware ESX/ESXi and vSphere environments, including vCenter, HA, DRS, and vSAN. I’m known for incident resolution, advanced troubleshooting, hypervisor patching and maintenance, and infrastructure change management in high-availability production environments.

In my recent roles, I’ve led ESXi/vCenter deployments, performed ESXi/VSAN/NFS cluster administration, and handled vSphere patching & firmware management. I’m currently expanding my Proxmox operational expertise through Proxmox deployments and migrations, having completed over 400 migrations, while also providing vendor H/W support for compute platforms.
