Software that
holds up when
it matters.
I build web and mobile platforms for teams who cannot afford for them to fall over. Ten years shipping production software — most recently taking a UK national platform from an empty repository to 175,000 concurrent users during live television advertising.

Four ways to work together.
Most of it comes down to the same thing: making the expensive technical decisions early, while they are still cheap.
Product build
Zero to launched product. You have a thing that needs to exist and a date it needs to exist by.
from £8,00002Scale & rescue
It works in staging and falls over in production. Or it works now and you know it won't in three months.
from £4,50003Fractional technical lead
You have engineers. You do not have someone senior enough to make the expensive decisions.
from £3,200/month04Technical due diligence
You are about to spend money on a codebase, a team, or a supplier. You would like to know what you are buying.

A national volunteering platform, built in eight months
175,000 peak concurrent users during national ITV advertising
Rebuilding an education marketplace into a commercial platform
Initial load cut to 2–3 seconds, with a monetisation model that shipped
Real-time arbitrage detection under adversarial conditions
High-frequency pricing across multiple exchanges, under hard latency constraints
Multi-format stream splitting for international sport
One camera source, many simultaneous output formats
No discovery theatre.
Four steps. You always know what happens next, what it costs, and who is doing it.
Conversation
Thirty minutes, free, no deck. You describe the problem. I tell you honestly whether I am the right person for it — and if I am not, who might be.
Scoping
A short paid discovery where the real requirements surface, the risks get named, and you get a fixed price with a fixed scope. No open-ended day rates disguised as a project.
Build
Weekly demos of working software, not status reports. You see progress in the client portal, and you can talk to the person writing the code, because that is the same person.
Handover
Documentation, infrastructure as code, and a system your own team can own. The goal is that you stop needing me, and come back because you want to.
Next step
Thirty minutes, no deck, and an honest answer about whether I am the right person for it.
