I am a business intelligence consultant and mentor. I started working on Analysis Services in 1998, back when Analysis Services was known as OLAP Services.
I wrote several books with Alberto Ferrari about Power BI, Analysis Service, and Power Pivot. We also regularly write articles and white papers that are available on sqlbi.com. I am a Microsoft MVP and an SSAS Maestro, the highest level of certification on Microsoft Analysis Services.
I spend most of my time with SQLBI customers, traveling extensively to train and consult on DAX and data modeling for Power BI and Analysis Services, teaching public classes worldwide.
I am a regular speaker at international conferences like Microsoft Ignite, PASS Summit, and Sqlbits - and I enjoy delivering evening sessions at local user groups during my trips.
