    BI Developer and some other nice things

    Poland - Last active: 24 days 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.

I've been designing websites, graphics, spreadsheets and software for over 17 years, over 95% from scratch. My specialty is the area having to do with "Direct Response" methods of lead generation, having studied almost every Dan Kennedy book and dozens of self-study courses over the years. I eat, breathe, sleep and dream sales and marketing. You think like an entrepreneur, and so do I...because that's almost all I've known for over a decade. I've been self-employed in some form my entire adult life. Borderline-obsessive work ethic is just another day at the office. I've gone through Tim Ferriss' "4-Hour Work Week" almost a dozen times.

It was on this day that my disdain for authority was born...) - I own (and actually completed) more sales, marketing, real estate investing, and real estate agent training courses than I can count (over 100 at least) - I hired a professional sales and marketing coach for approximately two years while practicing real estate, and amassed a well-rounded business education along the way - Barely old enough to vote, I spent 3 years selling telecommunications service and building sales teams I've also spent more time than I can count on: - Writing custom email campaigns - Writing eBooks and Free Reports for website give-aways - Designing custom graphics, flyers, and advertisements - Designing website elements (logos, buttons, banner graphics, backgrounds, etc) - Copy writing / sales letters (long- and short-form) Long story short: I have a strong background in the many aspects of internet-based sales and marketing, I love sales and marketing, and I'm a stickler for details.
