Network engineering
Routing, switching and security in the real world: BGP and EVPN fabrics, MPLS and segment routing, SD-WAN, firewalls and the change windows that go with them.

Network and systems consultancy Networks that behave.
Senior network and systems engineering for operators, enterprises and the teams who run them. We design it, build it, run it, or teach your people to.
Services
Six things we do well
Every engagement is led by an engineer who has run production networks and carried the pager for them. No account managers between you and the person doing the work.
Network architecture
Reference designs, addressing and segmentation plans, capacity models and the roadmap from where you are to where the business is going.
HLD · LLD · standards · reviews
Systems design and integration
The systems around the network: DNS, DHCP, IPAM, authentication, monitoring, automation and the glue between vendor platforms that never quite fit.
NetBox · Ansible · APIs · observability
NOC management
Standing up or straightening out a network operations centre: tooling, runbooks, escalation paths, on-call rotas and the metrics that tell you it is working.
24/7 · incident · change · reporting
Fractional CTO
Part-time technical leadership for companies that need the judgement without the headcount: strategy, vendor selection, budgets, hiring and board-level translation.
1–2 days a week · retained
Training
Hands-on courses in all of the above, taught by people who do the work. Lab-based, tailored to your gear, and pitched at the engineers you actually have.

How we work
Three ways to engage
Fixed-scope projects
A defined outcome, a written design, a price. Migrations, new sites, fabric builds, NOC stand-ups. We finish and hand over documentation your team can run from.
Retained engineering
A block of senior hours each month for reviews, escalations and the work that never makes it onto a project plan. Same engineer every time.
Leadership and training
Fractional CTO days, architecture reviews and courses that leave your people more capable than they were when we arrived.
A fair question
What's with the dogs, aren't you a tech consultancy?
Sure, but I love my dogs. Greyhounds are fast, quiet, and spend most of the day asleep until something needs chasing. Just how an engineer with a well behaved network would love to be.
Contact
Tell us what is not behaving
A short note about your network, your systems or your team is enough to start. We reply within one working day, usually with questions.
