ABOUT ME

Senior Business Intelligence Developer

I am a Senior Business Intelligence Developer with over 5 years and with 9 years professional experience in the IT area in total. I have specialized in the Microsoft technology stack including SQL Server, Reporting Services, Integration Services, Analysis Services, Power BI and Excel. I am a developer always looking for simple, yet high quality solutions. I know that communication is key in every project, especially when hiring a remote freelancer. So I am always looking to deliver soon and create profund solution to discuss the further development roadmap soon and often. When it comes to ETL processes my main goal lies in error robust and highly automated data flow chains. I am looking for technologically challenging projects with a horizon of several months of work in the Business Intelligence area.
