Selected work · one real business
Four systems a UK service business runs on daily. We built them and we run them.
Reconstructed & sanitised · real data and detail under NDA
01 · Knowledge
The first prototype embedded everything and hoped. It found the right document about once in twenty tries, and answered confidently when it missed.
Hybrid retrieval — vector plus keyword, reranked — and, more importantly, the measurement: an eval harness over a hand-labelled golden set, run on every change.
Recall@5 went from ~0.05 to ~0.85 on that golden set. That is retrieval recall — finding the right source — not answer accuracy. No change ships unless it beats the last version.
Q What's our policy when a job overruns its window?
Reschedule at no charge if flagged 24 h ahead policy·ops; otherwise the standard call-out applies pricing·rules.
02 · Decision support
A 24-month seasonal cashflow forecast, a rolling 13-week treasury view and a payroll-cover flag, plus an operations co-pilot scoring job risk from weather and route data.
Deterministic maths, unit-tested. Every figure traces to a ledger line, so when forecast and plan disagree you can follow the disagreement to its source.
03 · Revenue
Quotes waited on a callback, and enquiries went cold in the gap.
One pricing engine holds every rule, behind an instant-quote flow and self-service booking wired into the CRM and payments.
Online conversion more than doubled, and a large share of bookings now completes with no human touch.

04 · Automation
An integration layer joins CRM, field-service, finance and e-sign into one flow. If a webhook fires twice, one job is booked, not two; if an event drops, it retries until it lands.
Roughly half of routine office work now runs itself — around 200 staff-hours handed back each month — and month-end reconciliation is gone.
The shared spine
Records from CRM, finance, field-service and documents flow into one brain that answers in plain English and drives the tools above. For a small business it stands up in weeks, and one person can run it. The same spine scales to an enterprise: a brain per department, hundreds of users, single sign-on, role-based access, audit logs — and a human approving every write.

What it powers
I'll walk through any of these end-to-end — architecture, trade-offs and the actual figures — under NDA.
