04 / Infrastructure
Infrastructure strategy, hybrid and cloud, resilience and local AI, led by someone who has built the estates underneath.
I came up through the engineering, racking, cabling and commissioning real datacentre estates, and that is exactly what my architecture and leadership are now built on. Having done the physical work, I now lead the decisions above it: what to run where, what to modernise, and how to weigh commercial, operational and resilience trade-offs across physical, virtual and cloud.
That foundation spans government, NHS, policing, financial services, publishing, architecture, airports, MSPs and Crown Hosting environments, covering greenfield builds, zero-downtime migrations and infrastructure worth tens of millions, alongside several interim IT manager roles. Today I bring it to hybrid and cloud strategy, where sound decisions about what to move, keep or modernise depend on genuinely understanding what you are moving from.
The renewed interest in on-premises and hybrid infrastructure is a practical response to data sovereignty, AI inference economics and cloud licensing, and organisations increasingly need leaders fluent in both worlds.
Capabilities
Datacentre & infrastructure design
Own the design of datacentre and server-room estates, covering capacity, power and space strategy, resilience topology, and the standards facilities and engineering teams build to. Grounded in having done the build, now directed at architecture level.
Power & cooling
Set the capacity and resilience envelope: power budgeting, UPS and PDU topology (N+1, 2N) and thermal strategy, including the concentrated heat loads of GPU-dense AI hardware. These are the decisions that shape cost, uptime and headroom.
On-premises security & microsegmentation
Zero Trust does not stop at the cloud. I architect on-premises microsegmentation (VMware NSX, hardware-enforced boundaries), IAM and PAM, and network segmentation that blocks lateral movement across the estate, a layer cloud-native architects rarely cover.
Local AI infrastructure
As data sovereignty and inference economics pull AI back on-premises, I architect local GPU platforms, covering sizing, private inference endpoints, RAG on local data and converged stacks such as Nutanix GPT-in-a-Box, bringing private AI within reach of mid-market organisations.
Virtualisation & hypervisor expertise
Twenty-five years across the VMware arc, from ESX through vSphere, vSAN, NSX and Cloud Foundation, delivering virtualisation estates for the NHS, the Metropolitan Police, financial services, and central and local government. Through the post-Broadcom shift I lead hypervisor strategy and large-scale migrations, including VMware to Nutanix AHV programmes and Hyper-V assessments in cost-constrained environments, architecting the patterns that move production workloads between platforms with no service disruption. VCP, NCP and NCM certified.
These are programme-level decisions as much as technical ones, spanning licensing models, hardware compatibility, patching and firmware strategy, and the operating practices infrastructure teams depend on. I pair that with workload-level security: NSX and Nutanix Flow microsegmentation, tenancy isolation and in-cluster Zero Trust enforcement across hybrid physical and virtual estates.
