I work for almost 10 years in the area of information technology. To be more precise I owned my own software development company, focusing on windows based client developing under C#, WPF, SQL Server, WCF and all the good stuff that comes with it. While my team (and I) have been focusing on this side I got myself involved for the recent 4~5 years in the area of Business Intelligence. I am on an expert level in terms of data warehousing and business intelligence solutions under Microsoft Technology. SQL Server, Analysis Services, OLAP, MDX, DAX, PowerView, PowerPivot and even Power BI and Sharepoint is something that I work with on a daily basis. I am also very engaged in software development. That is what I learned back than and that is what lets me build a "face" on top of all that data analytics. My recent project was about an enterprise business planning suite developed in C#, WPF, WCF. It has just recently been rolled out to around 150 users all over the globe.
