Projects
World Town Guide in development
A fully automated travel guide and local information source covering 127,000 destinations worldwide. Built on a Software 3.0 architecture — EC2 with serverless Lambda for scalability, CloudFront for rapid global delivery.

Part 1 — information intelligence. An AI-engineered content pipeline that assembles researched information bundles for each destination and produces high-quality articles from source data. No human editorial involvement.

Part 2 — the elicit bot. An interactive chatbot that answers questions about any settlement in exchange for local knowledge from residents and visitors. The human element — crowd-sourced ground truth feeding back into the intelligence layer.

Investment and partnership enquiries welcome.
