Custom AI Software Development

Production-grade AI applications built around your actual business data.

Stop paying expensive agencies or relying on generic wrappers. I build custom AI software—from RAG pipelines and vector databases to document extraction (OCR) and AI agents—deployed in weeks, owned by you forever.

Sound familiar?

  • You’re paying an agency £20k+/month for AI features that could be a one-time build.
  • Off-the-shelf AI tools don’t understand your data, your workflows, or your domain.
  • Your team is duct-taping ChatGPT prompts into spreadsheets instead of having a real system.
  • You need AI that works with your existing stack — not another disconnected SaaS login.
  • Every “AI-powered” vendor locks you into their platform and charges per API call.

What you get

LLM Integration

Production-ready integrations with Claude, GPT-4, and open-source models. Prompt engineering, guardrails, and structured output — built into your application.

RAG Pipelines

Retrieval-augmented generation that grounds AI responses in your actual documents, knowledge base, and business data. No hallucinations, no generic answers.

Vector Databases

Semantic search and embedding storage with Pinecone, Weaviate, or pgvector. Your data indexed and queryable by meaning, not just keywords.

AI Document Extraction

OCR and intelligent document parsing for contracts, invoices, receipts, and forms. Structured data extraction with validation and confidence scoring.

AI Agents & Workflows

Autonomous agents that execute multi-step business processes — from research and data enrichment to customer support triage and content generation.

You own it

No per-call API markups. No vendor lock-in. The code, models, and data belong to you permanently.

How it works

I start by understanding your data, your workflows, and what you actually need AI to do — not what sounds impressive in a pitch deck. Then I scope a fixed-price build: data pipeline, model integration, application layer, and deployment. Build time is typically 4–8 weeks. You get a production system with documentation, monitoring, and team training.

// Migration Plan

How we migrate you off — without the risk

Every migration follows a proven 4-step process. No downtime, no data loss, no surprises.

01

Schema & Data Mapping

We extract and map your existing data, configurations, and business rules with zero downtime. No disruption to your live environment while we build the blueprint.

02

Logic Recreation

Your exact workflows, pricing matrices, approval chains, and automation rules are rebuilt in clean, documented code — not approximated or templated.

03

Sandbox Testing

The new system runs in parallel alongside your existing tool. Your team validates every workflow, edge case, and integration before anything changes.

04

Hard Cutover & Training

One clean switch. Your team gets hands-on training, full documentation, and direct access to the developer. Cancel your old licenses the same week.

Frequently asked questions

What LLMs do you work with?

Claude, GPT-4, Gemini, Llama, Mistral — whatever fits your use case, budget, and data privacy requirements. Most builds use Claude or GPT-4 for quality, with the option to swap models without rewriting your application.

Can you work with our existing data and systems?

Yes. Every build starts with your existing data sources — databases, CRMs, document stores, APIs. The AI layer plugs into what you already have, not the other way around.

How do you handle data privacy and security?

Your data stays in your infrastructure. We deploy on your cloud (AWS, GCP, Azure) with your API keys. No data leaves your environment unless you want it to.
