Sound Familiar? These Are the Problems UK Businesses Tell Me Every Week
These are exactly the problems I solve. Every single day. For UK businesses
❌
Broken LLM API Integrations
UK businesses waste weeks dealing with unstable API connections, inconsistent responses, and poorly architected LLM integration layers.
❌
Hallucinating AI Responses
LLMs confidently produce wrong, fabricated answers destroying user trust and exposing UK businesses to serious reputational damage.
❌
GDPR & UK Data Compliance Risks
Most LLM integrations are built without UK-GDPR compliance, leaving businesses exposed to ICO penalties and data breaches.
❌
AI Pilots That Never Reach Production
UK teams build impressive AI prototypes that stall permanently unable to scale into stable, production-ready business systems.
❌
Uncontrolled LLM API Costs
Unoptimised token usage and poor model selection silently inflate monthly AI running costs far beyond initial budget expectations.
❌
Legacy Systems That Can't Talk to AI
Outdated UK business infrastructure has no native way to connect with modern LLM APIs and AI workflows.
❌
Weak AI Search & Knowledge Retrieval
Traditional keyword search fails to surface relevant internal knowledge leaving UK teams frustrated, slow, and poorly informed.
❌
AI Security & Prompt Injection Vulnerabilities
Unsecured LLM integrations are vulnerable to prompt injection attacks, unauthorised data access, and serious AI-specific security exploits.

Clients Testimonials
What UK Clients Say About Working With Me
Real results from real UK businesse no made-up reviews, no agency fluff. Just honest feedback from clients who trusted me to build their AI solutions from scratch.
Honestly didn't expect this level of quality. He just got it knew exactly what we needed and built it without a dozen back and forth calls. RAG pipeline works beautifully.
We'd tried two other developers before this. Night and day difference. The OpenAI integration was solid, well documented, and he flagged GDPR issues we hadn't even thought about
Refreshing to work with someone who actually knows the LLM stack properly. Not just copy pasting tutorials he understood the architecture deeply and it showed in the final code
We were stuck for months. He came in, asked the right questions, and within weeks we had something actually working in production. Wish we'd found him sooner honestly
Straight talking, no fluff. Told us exactly what was needed, built it, and didn't disappear after handover. The Claude API integration has been running without issues ever since.
What stood out was he flagged problems before they became problems. Our old system connecting to the LLM API felt impossible he made it look easy. Really impressive.
Questions People Usually Ask Before Getting Started
I'm not very technical can you still help me?
Absolutely. Most of my clients aren’t deeply technical and that’s completely fine. You don’t need to understand how LLMs work under the hood that’s my job. You just need a clear idea of the problem you’re trying to solve and I’ll handle the rest.
How long does an LLM API integration typically take?
Honestly it depends on how complex your setup is. A straightforward OpenAI or Claude API integration can be done in a couple of weeks. If you’ve got legacy systems involved or need a full RAG pipeline built from scratch, it usually takes four to six weeks. I’ll give you a realistic timeline upfront no surprises.
Will my data be safe and GDPR compliant?
Yes and this is something I take seriously. Every integration I build is designed with UK-GDPR and ICO requirements in mind from day one. I don’t bolt compliance on at the end. Your data stays secure, properly handled, and fully auditable throughout.
Do you offer ongoing support after the build?
Yes.I don’t just hand over the code and disappear. Once your LLM integration is live I’m available for ongoing support, monitoring, and iterations as your needs evolve. A lot of my clients come back for new features once they see what’s possible.
