Mark J. Brummel is an all-round Microsoft Dynamics NAV specialist. He started in 1997 as an end user but quickly moved to the other side of the table. During ten years, he has worked for resellers where designing and maintaining add-on systems was his specialization. Some of these add-on systems exceed the standard product where it comes to size and complexity. In addition, coaching colleagues and troubleshooting 'impossible' problems is his passion and part of day to day work. Mark has trained most of the experienced NAV developers for the NAV 2009 product in The Netherlands and Belgium. Today he is working freelance, is hired by almost every NAV reseller in the Benelux area, and is also frequently asked to help out in escalated implementations by end users. Mark is an associate in the Liberty Grove Software network and a business partner of SQL Perform Benelux. Mark was the first to use the NAV 2009 (CTP3) product in a production system feeding back valuable information to Microsoft.
A special project and passion is performance tuning of the Dynamics NAV product on SQL Server. Since 2007, he is involved in the development of the 'SQL Perform Tools'. A specialist's toolset which allows both trend and escalation analysis of key elements for systems speed. As a unique specialist, he has done break-through research in improving the performance of Dynamics NAV on SQL Server.
In his free time, Mark maintains his blog on www.brummelds.com. This blog contains a wide range of articles about both the Microsoft Dynamics NAV and SQL Server product. He is also a frequent speaker at Microsoft events. In 2006, Mark was rewarded by Microsoft with the Most Valuable Professional award for his contribution to the online and offline communities.
