UK AI Developer · Production-Grade · Not Just Demos

The UK's ExpertAI Developer.Built Real. Shipped Real.

I build AI-powered products that work in the real world — not prototypes that impress in a pitch deck and fall apart in production. From ChatGPT and Claude integrations to full RAG pipelines and AI-native SaaS platforms, I've been shipping production AI since before most agencies had an “AI team”.

The Reality

What Most “AI Developers” Get Wrong

The term AI developer has been diluted. There are now thousands of developers who can wrap an OpenAI API call in a Next.js app and call themselves AI developers. That's not what I do.

The difference is production experience. Building AI that works in a demo is trivial. Building AI that handles real data, real users, real edge cases, integrates with existing systems, and keeps working at scale — that's hard. That's what I've done.

I founded Cynfia, an AI platform built on retrieval-augmented generation that processes real business knowledge and serves it through a conversational interface. Not a side project or a proof of concept. A real product used by real businesses.

That's the level of AI development I bring to every project.

Generative AI Integration

You have an existing product — web app, mobile app, SaaS platform — and you want AI built into it. Not bolted on. Built in. I integrate Claude, ChatGPT (GPT-4o), and Gemini into your product in a way that actually makes sense for your users — conversational interfaces, image analysis, document processing, automated workflows, smart recommendations.

Best for: SaaS founders, app owners, businesses with existing products who want AI capability added by someone who's done it before.

RAG Pipelines & Custom AI Knowledge

RAG — Retrieval-Augmented Generation — is how you train an AI on your business data without the cost and complexity of fine-tuning a model. I build secure, production-grade RAG pipelines that connect your data to AI. Whether that's documentation, customer knowledge bases, product catalogues, legal libraries, or proprietary data — I architect it properly so it scales, stays accurate, and doesn't leak sensitive data.

Best for: Businesses with large bodies of knowledge (legal, medical, compliance, finance, ecommerce, SaaS) who want AI that actually understands their domain.

AI-Native App Development

Building from scratch and want AI at the core from day one — not added later as an afterthought? I build AI-native mobile and web apps where intelligence is part of the architecture. Flutter for mobile, Next.js for web, Supabase for the data layer, and whichever AI API fits the use case. The stack is chosen for each project, not templated.

Best for: Founders building new products, startups, anyone who wants to build the AI version of something rather than the traditional version.

AI Chatbots & Conversational Interfaces

Not the generic chatbot that answers "what are your opening hours". I build AI chat interfaces that understand context, handle complex queries, integrate with your business systems, and actually reduce the load on your team. Customer support AI, internal knowledge assistants, sales qualification bots, document Q&A interfaces — built properly, with guardrails, with fallbacks, with logging.

Best for: Businesses spending too much on customer support, companies with large knowledge bases, SaaS products that need in-app AI assistance.

AI MVP Prototyping

Have an AI idea and need to know if it works before committing to a full build? I take AI concepts from back-of-napkin to testable prototype in 4–8 weeks. Fast enough to show investors. Real enough to get actual user feedback. This isn't a clickable mockup — it's a working AI product with real data, real AI responses, real infrastructure, built to a standard that can be iterated into a full product.

Best for: Founders raising investment, businesses validating an AI concept, anyone who needs to show rather than tell.

AI Strategy & Consultation

Not ready to build yet? Or not sure what to build? I offer strategic AI consultations for businesses trying to figure out where AI fits, what it costs, and what it would actually take to implement. One session. No agency sales pitch. Just an honest assessment from someone who's built production AI and knows what works.

Best for: Business owners, CTOs, product leaders who want a straight answer on AI feasibility and cost before committing budget.

The Difference

Why Senior AI Development Matters

Most AI projects fail. Not because the AI doesn't work — it does. They fail because of how it's built. Prompts that work in testing but not in production. No fallback when the API goes down. Data architecture that makes RAG inaccurate. Costs that spiral because nobody thought about token efficiency. I've built enough production AI to know all of these failure modes. I architect around them from the start.

What you get with a senior AI developer:

Prompts engineered properly — not just copied from a tutorial
Guardrails so the AI stays on-topic and on-brand
Fallbacks when APIs fail or return unexpected results
Token cost management so your API bill doesn't spiral
Proper data architecture for RAG that keeps results accurate
Logging and observability so you can see exactly what the AI is doing
Security — your data doesn't go where it shouldn't

Proof of Work

Cynfia — AI Built in Production

I don't just integrate AI. I've built an AI platform.

Cynfia is an AI knowledge platform I founded and built from scratch. It uses retrieval-augmented generation to allow businesses to train AI on their own data and surface that knowledge through a conversational interface.

Building Cynfia taught me what production AI actually requires — the difference between getting a good response in a demo and getting consistently good responses at scale, with real data, across thousands of interactions. Every project I take on benefits from that experience. I've already made the mistakes. I know what not to do.

Good Fit

Who I Work With

🏗️

Founders building AI-native products

You have an idea, you know AI is central to it, and you want someone who can build the whole thing rather than stitching together three different agencies.

🛠️

SaaS companies adding AI

You have an existing product and you want AI integrated properly by someone who understands both the AI layer and the product layer, not just one or the other.

🎯

Businesses with a specific AI problem

A knowledge base that's not working, customer support volume you can't keep up with, or a manual process that AI should automate. You want it solved, not theorised about.

FAQ

Common Questions

How much does AI development cost in the UK?

AI development projects typically range from £8,000 for a focused integration or MVP through to £50,000+ for a full AI-native product build. The biggest variable is scope — specifically how much data architecture and RAG infrastructure is involved. I give honest, fixed-scope quotes after an initial conversation, not vague day-rate estimates.

How long does an AI project take?

A focused AI integration into an existing product: 4–8 weeks. An AI MVP built from scratch: 6–12 weeks. A full AI-native SaaS product: 3–6 months. These are real timelines, not optimistic estimates.

Do you work with OpenAI or Claude specifically?

Both, and Gemini. The right API for your project depends on what you're building — Claude is exceptional for document processing and nuanced text tasks, GPT-4o for multimodal and vision work, Gemini for Google ecosystem integration. I recommend based on fit, not preference.

What is RAG and do I need it?

RAG (Retrieval-Augmented Generation) is the technique that lets AI answer questions about your specific data. If you want an AI that knows your products, your documentation, your policies, or your customer history — you need RAG. If you just need general AI capability in your product, you may not. I'll tell you which applies to your situation.

Can you add AI to my existing app?

Yes — this is one of the most common projects I take on. Existing Next.js, Flutter, React, or any other stack. I integrate the AI layer without breaking what's already working.

Are you available for contract/freelance AI work?

Yes. I work on a project basis with fixed-scope quotes, or on a retainer for ongoing AI development. I'm based in Hertfordshire, UK — remote-first but available for on-site in London and the South East.

Ready to Build Something With Real AI?

No demos. No vague estimates. Tell me what you're building and I'll tell you exactly what it takes to build it properly.
