I understand the live environment
Good architecture has to survive real customers, real traffic, carrier faults, change windows and commercial pressure, not just look tidy in a diagram.
Independent network architecture and cyber security consultancy
Hello, I’m Matthew.
I design networks that businesses rely on.
I work directly with MSPs, ISPs and technology consultancies to solve complex BGP, IPv6, resilience, DDoS and 100G infrastructure challenges, without layers of junior consultants or account management.

You work with me, not a revolving project team.
I have spent more than two decades designing, operating and troubleshooting networks. I built 39D into an award-winning MSP and remain hands-on because critical infrastructure decisions deserve direct senior attention.
I strengthen your existing team
I can work openly, as a specialist subcontractor, or white-labelled behind an MSP or larger consultancy while protecting your customer relationship.
I stay through delivery
From discovery and design through migration, testing and handover, I remain involved when the important decisions and difficult moments happen.
What I help deliver
Specialist capability for projects where mistakes are expensive.
The work is technical, but the outcome is simple: networks that are safer to operate, easier to scale and more resilient when something goes wrong.
