Four ways I work with CTOs, programme directors and architecture teams, from a review before you sign to leading delivery with your engineers.
An independent review of a vendor or in-house design before you commit: security, integration, scalability, resilience and cost, tested against your real volumes.
Azure-first platform design and delivery, from landing zone to production: infrastructure as code, containers, networking and zero-downtime migration.
Data, integration and geospatial platforms, and AI built into products: pipelines, search, vector tiles, MCP servers and evaluation in CI.
A hands-on lead and architect for your delivery teams: designs, prototypes and infrastructure as code alongside the engineers, through to go-live.
Engagements from the last six years, plus a product of my own.
Moved production to Azure best practice with Terraform, ran old and new architectures side by side during migration, and redesigned for multiple AKS clusters per region behind a hub-spoke network.

UK schools
From software engineer in 2009 to independent architect today.
Maxis GBN
Independent technical assurance of a vendor’s proposed Azure architecture integrating Salesforce, Boomi and an Azure data warehouse: validation against the Well-Architected Framework, a programme risk register, measurable non-functional requirements and ongoing architecture governance.
Knight Frank
Hands-on lead for a shared data, integration and mapping platform on Azure, and the products built on it: lease expiry, sanctions screening and development scheme management.
Landmark
Cloud architecture across energy and land-sector engagements: an in-depth review and remediation for HM Land Registry, designs and proofs of concept for the Central Switching Service, and support for bids and proposals.
Kainos (NHS App)
Re-architected the NHS App’s production environment to Azure best practice with Terraform, for over 30 million users and a zero-downtime SLA.
Earlier: technical lead and architect at Landmark Solutions; technical lead at Landmark and Searchflow; integration architect at Smarts Solutions and Octavia; software engineer and team leader at Aareon UK from 2009.
I’m a solution and cloud architect based in London. I started as a software engineer in 2009 and have since designed, built and led delivery of platforms on Azure, AWS and GCP for housing, property, energy, health and education.
I stay hands-on. I still write Terraform, Bicep, TypeScript and Python, and I work with AI coding agents every day. I have built MCP servers, LLM evaluation pipelines and real-time voice products, and I bring that experience to teams adding AI to their own products.
