I worked with Xavier for several years developing and supporting the Microsoft interal MBS Navision based billing application. He was was a very valuable data analyst when we were troubleshooting complex data issues, while he was based in Dublin and I was in Denmark, but also when we were colocated in Denmark and in the war rooms in Dublin. Our online cooperation ws great and problems got solved fast. His SQL and Navision skille was a great help.
