Ben Walker

About

I'm Ben Walker, a consultant-turned AI engineer based in Eastbourne, UK.

For many years I've worked with large organisations to design and deploy software solutions in complex, real-world environments, where security, reliability, stakeholder alignment, and "getting it live" matter as much as the architecture.

Today I bring that same delivery mindset to modern AI: building LLM-powered applications, RAG systems, and agentic workflows that turn messy business requirements into practical tools teams can trust.

My edge sits at the intersection of enterprise consulting and hands-on engineering, bridging the gap between what the business needs, what's technically feasible, and what's maintainable in production.

Outside of tech, you'll usually find me playing guitar, or out in nature with a camera, drawn to landscape and nature photography, and the headspace that comes from being outdoors.
