Chris Ratcliffe

I build practical AI tools, websites, prototypes and interactive digital experiences for organisations that need useful, reliable systems rather than hype.

My work combines LLMs, RAG, OpenAI APIs, TypeScript, Node.js, web design, UX, animation, prompt design, workflow automation and production-facing delivery. I have built AI assistants, document-led knowledge systems, websites and digital prototypes for publishing, brand engagement, legal/property workflows, HR diagnostics and enterprise innovation.

My background spans web design, 3D animation, creative technology, virtual events, SaaS prototyping and immersive digital experiences. I am strongest where product thinking, visual design, technical build and AI behaviour design need to come together quickly in a working prototype, pilot or public-facing digital product.

I also design AI evaluation and quality workflows, including prompt evaluation, RAG evaluation, retrieval testing, grounding checks, hallucination detection, regression testing and human-in-the-loop review.
