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
❌
Generic AI Models That Miss Your Industry Context
Off the shelf LLMs know nothing about your specific industry terminology, internal processes, or unique business language causing constant inaccurate outputs.
❌
Hallucinating AI Responses Damaging Business Credibility
Generic large language models confidently produce wrong domain specific answers, destroying customer trust and exposing UK businesses to serious reputational damage daily
❌
Expensive Commercial LLM Costs Draining Budgets
UK startups and SMEs pay enormous ongoing API fees for commercial LLMs when a fine tuned open source model would cost significantly less
❌
No Control Over Your Own AI Model
UK businesses using third party commercial LLMs have zero control over model updates, pricing changes, and data handling decisions affecting their business
❌
Training Data Handled Without GDPR Protection
UK businesses send sensitive proprietary data to commercial LLM providers without fully understanding their UK GDPR obligations around model training data
❌
AI That Cannot Understand Industry Specific Language
Legal, financial, and healthcare UK businesses struggle with generic LLMs that completely misunderstand critical domain specific terminology and sector language constantly
❌
Poor AI Performance on Specific Business Tasks
Generic LLMs perform adequately on general tasks but consistently underperform on the specific, specialised business tasks UK companies actually need them for
❌
No Private Hosting Option for Sensitive AI Models
UK businesses in regulated industries cannot use cloud hosted commercial LLMs because data sovereignty, privacy requirements, and ICO compliance rules prevent it entirely
What Is LLM Fine Tuning Developer and Custom Model Training?
A large language model like LLaMA or Mistral already knows a lot. But it does not know your business. LLM fine tuning takes that existing model and trains it further on yourspecific data, your industry language, your terminology,
and your use cases. The result is an AI model that stops giving generic answers and starts giving accurate, relevant responses that actually make sense for your
specific business and industry.

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.
We were using GPT4 for customer support but it kept misunderstanding our technical terminology. He fine tuned a Mistral model on our product documentation and the accuracy improvement was honestly remarkable. Our support team cannot imagine going back now.
We needed an LLM that understood financial regulatory language specifically. Every generic model we tried failed badly on compliance related queries. He built a fine tuned model on our proprietary data that handles them accurately every single time
The commercial LLM API costs were killing our margins. He fine tuned an open source LLaMA model that we now host privately. Performance is better than the commercial version and our monthly AI costs dropped by around 60 percent
We had tried fine tuning internally for four months without success. He came in, assessed our training data, rebuilt our dataset properly, and delivered a working fine tuned model in three weeks. Should have called him at month one
Legal language is incredibly specific and generic LLMs handle it poorly. He fine tuned a model on our case documents and contract templates. It now drafts and reviews legal language with an accuracy our partners genuinely find impressive.
GDPR was our biggest concern handing over proprietary training data. He structured the entire fine tuning process around our compliance requirements from day one. Fully auditable, ICO compliant, and our legal team signed off without a single concern raised.
Our existing data science team understood ML but had no fine tuning experience with LLMs specifically. He upskilled the team during the project and delivered a production ready model. We now maintain it internally without any external dependency
We operate in healthcare and needed an AI model that understood clinical terminology without sending patient data to commercial providers. He fine tuned a privately hosted model that meets all our data sovereignty requirements. Exactly what we needed
Honest answers about LLM Fine Tuning Developer and Custom Model Training
What is the difference between fine tuning and prompt engineering?
Prompt engineering adjusts how you talk to a generic model. Fine tuning actually changes the model itself by training it on your specific data. The result is significantly better accuracy, consistency, and domain awareness that prompt engineering alone cannot achieve.
How much data do I need to fine tune an LLM?
Less than most people think. High quality focused datasets consistently outperform large messy ones. I assess your existing data first and tell you honestly whether it is ready for fine tuning or needs preparation work before we start.
Can you fine tune a model on sensitive business data safely?
Yes. Every fine tuning project I deliver follows UK GDPR and ICO standards from day one. Sensitive data stays within your controlled environment, nothing gets sent to third party providers, and the entire process remains fully auditable throughout.
How long does LLM fine tuning typically take?
Most fine tuning projects are complete within three to five weeks depending on dataset size and complexity. I scope everything clearly upfront, give you realistic timelines, and keep you updated throughout the entire process with no surprises.
