    BI Developer and some other nice things

    Poland - Last active: 1 month ago - Tests: 4

    I started my career as C++ developer, then I moved to Visual Basic and SQL, but when things are getting serious you start to use a real database, so I learn PL/SQL and from there I moved to Data Warehousing and Business Intelligence. Moving abroad was only the next natural step in my search for more interesting and challenging projects. I admit it, a girlfriend was a good reason too. I think I passed the test, if I still have no intention to come back to mamma. When I joined MicroStrategy I knew only that I enjoyed my time with the rudimentary BI tool I was using, I knew something more was out there. With my Oracle and programming background I started working on ETL and Data Modelling projects, but you don't do BI if you don't understand your customer's business. Finally a way to combine my job and my communication degree. In the last four year I have be travelling around the world working in different environments and having my part of fun doing it, and I was lucky enough to do it adding new experiences and skills to my curriculum. And a wife as well. And now? now I'm looking for the next step in my life.
