Description

If you're looking for an engineer who can build production-ready AI applications from end to end, I can help.

I specialise in building AI-powered applications using Python, FastAPI, React, and modern LLM frameworks. My expertise includes Retrieval-Augmented Generation (RAG), AI agents, REST APIs, and scalable cloud architecture, delivering complete solutions from backend to frontend.

With over 20 years of software engineering experience and a degree in Computer Science from the University of Teesside, I combine modern AI technologies with proven engineering principles. I focus on building applications that are scalable, maintainable, secure, and designed for production—not just demos.

Whether you're integrating AI into an existing product or creating something new, I can design and build the entire solution. My backend-first approach ensures AI features are supported by robust APIs, databases, and cloud infrastructure, while React provides intuitive, responsive user experiences.

Typical projects I work on:

• AI applications powered by LLMs

• Retrieval-Augmented Generation (RAG)

• AI agents and agentic workflows

• Full stack applications (Python, FastAPI, React, Tailwind CSS)

• REST API design and backend development

• PostgreSQL and vector databases

• Cloud infrastructure (AWS, GCP, Docker)

• Refactoring and modernising existing applications

I enjoy working with startups and established businesses to turn AI ideas into reliable, production-ready software. Whether you need a new AI application, intelligent search, document Q&A, workflow automation, or a scalable full-stack platform, I can help deliver it.

I'm currently offering an introductory rate on Malt while I build my presence on the platform. If you're looking for an experienced AI and full stack engineer to build scalable, production-ready solutions, I'd love to discuss your project.
