Production RAG and AI agents
I'm Tony James, a senior, hands-on applied AI and full-stack engineer based in Milton Keynes, UK. I build production software for businesses at freelancer rates. AI-assisted delivery keeps overhead down; I own the code, testing and what ships.
Who this page is for
UK product and engineering teams that need production RAG systems and AI agents trained on their content — not demo chatbots. Prefer RAG development and production AI phrasing over vague “applied AI hire” labels.
What I take on
- Production AI agents and RAG systems trained on your content
- High-volume APIs and integrations
- Legacy backends modernised into modern services
- Web applications end-to-end — database, API, interface, tests and deploy

How engagement works
Contributions within client teams, separate from independent products. You talk to me; I do the building. Agree scope and price with a clear quote. Build, review, hand over.
Alongside products
Independent products (Flow Chat, Arc, Macroline, Order Now) are separate from client engagements — see Services and All work. Charities can apply for at-cost work.
