For 10 years, Steve Dark was a SQL Server / MS ASP developer building web based reporting solutions, until he was shown a demo of QlikView. Soon after this revelation, Steve left his previous employer to set up Quick Intelligence – a consultancy focusing entirely on QlikView and delivering business intelligence solutions. Preferring to stay at the coal face, Steve spends the majority of his time with clients building QlikView applications, managing QlikView deployments, and running projects.

He will never tire of showing QlikView to new users and seeing that "jaw drop moment".

Steve is active on QlikCommunity and other social media sites sharing his enthusiasm for QlikView and assisting other users. Through his blog, he shares tutorials, examples, and insights about QlikView (read it at http://www.quickintelligence.co.uk/).

Steve was also the technical reviewer of QlikView 11 For Developers by Barry Harmsen and Miguel García, Packt Publishing.
