Engineering for brands whose products carry regulated claims

Find what your business thinks is working — but isn’t.

Your storefront says one thing. Your email platform says another. I inspect the joins by hand, prove what is broken with a reproduction path you can run yourself, and fix what is worth fixing.

From one real inspection · 2026

One account-wide setting had quietly parked 6,601 records. The email platform could reach about 150. For fifteen months, nothing anywhere said a word.

One of three findings published here, reproduced before reporting.

Prefer to describe a stuck workflow instead? One sentence by email is enough.

Evidence you can reproduce

One inspection. Six verified failures, invisible from inside.

One private engagement with a small independent British supplement business, inspected in 2026. Six findings were reported privately, each reproduced before it was reported; five sat between two systems, in a join nobody owned. Three are published, with the path to check each one yourself. The business is not named and never will be: a client’s private weakness is not my marketing asset.

Observed · Reproduced · Not proven — stated on every finding. Read the findings and how they were checked

The method

How an engagement runs

Analyse. £150 fixed. An agreed public surface of your business, examined from outside. No credentials, no access to your accounts.
Inspect. £750 fixed. One workflow you name, followed read-only across the systems it crosses, agreed in writing first.
Build. From £2,500. Scoped and priced in writing before it starts, and only where the evidence justifies building something. The destination rung is often an operating system for the whole company, on your server.
Operate. From £750 a month. Only where there is a real recurring workload worth operating. Your business keeps the system.

Every step is complete in itself and refusable, with a fixed price stated in writing before any work begins. If the inspection does not justify the work, I decline it. What each step costs, and what it does not buy · how the work runs, in detail

Selected work

Also built: three systems for an EASA-regulated training business

Sofema Aviation Services trains engineers under EASA regulation, where a wrong answer carries a regulatory cost. A training ROI calculator and a course finder are live in production on their site. A cited EASA answer system is still in development. All were built agent-assisted and human-directed.

The model

Agents produce. One engineer answers. Your people decide.

A directed team of AI agents gives one senior engineer unusual capacity: they read, test, draft and propose inside agreed boundaries; I brief them, verify their work against each other and merge what survives. Judgement does not delegate. A named person in your business approves anything that changes state or reaches a customer. The system of record, source, credentials, workflow definitions and operating records live in infrastructure your organisation controls; where an approved external provider processes data, including an AI model, I document what leaves the environment, why, and who processes it. No dependency is hidden.

Start with the analysis. £150, fixed.

You write to me with your domain and the public surface you want examined.
I agree the scope and the price with you in writing before anything begins. If it is not work I can do from outside, I say so then and there is no invoice.
You receive one written report in which every finding is marked observed, reproduced or inferred, and which ends by stating what I could not establish from outside.

No credentials · no access to your accounts · no meeting required · no list, no sequence, no call unless you ask.

Holding the letter? The check it describes takes about a minute: your two numbers.

If the analysis tells you nothing you didn’t already know, tell me and the invoice is cancelled.

What the analysis covers

Ready to ask for one, or want to describe a stuck workflow first? Write to me in one sentence. I reply within one working day; if it does not fit, I will say so and point you somewhere better if I can. What happens to your details · what each step costs.
