David has over 17 years experience as a “non technical guy in a technical envrionment” specialising in bridging the gap between Business and Information Technology.  With a background originally in telecommunications, David has spent most of the last 5 years working with some of the UKs biggest retailers spanning High St supermarkets, pharmaceuticals/health & beauty and electronics & consumer goods, mainly focused on defining the long term vision and bringing IT closer to the business.

David’s main interest in technology lies in the way that innovative technologies are increasingly used as an enabler to changing operating cultures and customer interaction models, and in particular in how modern businesses must adapt to the challenges of a customer-led technology landscape where the customer increasingly calls the shots about how they want to interact and do business.
