Joost van Rossum is a Data Warehouse / Business Intelligence consultant for 10 years with a focus on the Microsoft SQL Server stack, and especially on SQL Server Integration Services. He speaks and blogs (http://microsoft-ssis.blogspot.com) about SSIS, and he answers and moderates questions in the Integration Services Forum on MSDN. This gives him a lot of knowledge about the problems that SSIS developers encounter during their daily work. Before his DWH / BI career, van Rossum worked as a developer with JavaScript, VBA, ASP, ASP.Net, C# and VB.NET, and tools like Microsoft Content Management Server and Microsoft SharePoint Portal Server. With this knowledge he knows well how to apply .NET to scripting solutions in SSIS.
