I'm working with MS Dynamics NAV (formerly Navision) since 1997 within the areas Project-Management, Consulting & Development.
Since 2003 I'm intensively working on the topics "Performance Optimization & Troubleshooting", especially when it's up to NAV with SQL Server.
Since 2006 I'm supporting Dynamics customers and partners within their NAV projects as a freelancer.
I'm developing & distributing the optimization utility "The NAV/SQL Performance Toolbox" and I am the author of "The NAV/SQL Performance Field Guide" (ISBN 978-3-8370-1442-6).
I have been awarded by Microsoft as "Most Valuable Professional" (MVP) in 2007, 2008 and 2009.
The British NAV community "Dynamics World" (http://www.dynamicsworld.co.uk) voted me on rank #38 of the "Top 100 Most Influential People in the Dynamics World" in 2009 and on rank #13 in 2010!
