I  have been working with SQL & BI for the last 4 years having started as a fully self taught Analyst. Since then I have set up two BI departments within my last two organisations, taking them out of the "Stone Age" of legacy excel and power point based reports, to a nice new and shiny Cloud based reporting suite encompassing SSRS and Power Bi. I am waiting for the call any day now from Microsoft asking me to be head of PR for Power BI.
