Where does it hurt?
Clients usually call us in one of these situations.
You have a new product idea
You know what it should do. You need it designed, built and live without hiring a team first.
Delivery →An old system is holding you back
It still runs the business, but every change is slow and risky, and the people who understand it are leaving.
Delivery →You built a prototype with AI
It works in the demo. Real customers, real data and real money are about to arrive.
Delivery →You want AI in your product
A feature your customers can rely on, with its security and running costs under control.
Delivery →A big technology decision is on your desk
Build or buy, which vendor, whom to hire, what an investor will find. You want an experienced opinion before you sign.
Advisory →Your team needs to catch up with AI
They are experimenting already. You want them working safely and productively on your own systems.
Training & Workshops →Three services, each a fixed-price package
Priced as packages, never by the hour. We take a small number of engagements at a time, so every change gets senior review.
Advisory
Senior judgement when a decision is expensive to get wrong: architecture, vendors, hiring, security reviews, technical due diligence and a fractional CTO on call.
Fixed monthly retainer or fixed-price review
How advisory works →Training & Workshops
Private workshops for leadership and engineering teams, on-site in the UK or online, built around your own systems and ending with a plan.
Priced per team, quoted on the scoping call
See the workshops →Delivery
We build it: new products and SaaS platforms, replacements for systems that have reached their limit, and AI features that hold up in production.
Fixed-price packages, quoted before work starts

Understand
What the business needs, what exists today, and what would make this a failure. Written down and agreed.
Prove it small
The riskiest part gets built first, as working software, so the plan and the price rest on evidence.
Build in slices
Each milestone is usable and tested. AI coding agents do much of the typing; every change gets senior review.
Hand over
Security review, monitoring and documentation. You own the result, and we can keep it running if you want.
I’m a software architect with 22 years in enterprise systems across energy, insurance, logistics, automotive and pharma, including programmes at Schlumberger, E.ON, Saga, Loomis, Škoda Auto and MSD Animal Health. MSc in Software Engineering.
We also build and run SaaS products of our own with AI coding agents, so our advice on tools, costs and what AI can really do comes from production software.
We take a small number of clients at a time, so the person you talk to is the person who reviews the work.
