To be more precise I owned my own software development company, focusing on windows based client developing under C#, WPF, SQL Server, WCF and all the good stuff that comes with it. While my team (and I) have been focusing on this side I got myself involved for the recent 4~5 years in the area of Business Intelligence. I am on an expert level in terms of data warehousing and business intelligence solutions under Microsoft Technology. SQL Server, Analysis Services, OLAP, MDX, DAX, PowerView, PowerPivot and even Power BI and Sharepoint is something that I work with on a daily basis. I am also very engaged in software development. That is what I learned back than and that is what lets me build a "face" on top of all that data analytics. My recent project was about an enterprise business planning suite developed in C#, WPF, WCF. It has just recently been rolled out to around 150 users all over the globe.

    Denis N.

    Software Engineer

    Russia - Last active: 1 month ago - Tests: 10

    I started programming at age of nine and have accumulated incredible amount of experience since then. Also the years of serious participation in programming competitions have forced me to learn a lot of non-trivial programming algorithms and trained me to write highly efficient quality code. At the first stage of my career my passion was game development. Now I mostly enjoy programming applications for web, mobile and desktop. My main priorities in software development are: - paying great attention to quality of my code; - caring about code maintainability and testability very much; - striving to learn new techniques that help improve my productivity even more.
