    .NET, ASP.NET, SQL, HTML5 developer

    Russia - Last active: 07/08/2014 - Tests: 10 - Portfolio: 5

    Since 2005 I've created various solutions in a team and as standalone developer. My expertise lies in MS .NET, web and databases technologies. I've used for my work a great number of these technologies. I think the main principle in software development of long running projects is making the code clean. In this way I understand users' needs and write easy readable and working programs. I use such methodologies and principles as TDD, DRY, DoC, design patters and other. I take responsibility for what I write and how long it takes. My favorite editor is VIM and my favorite SCCS is GIT. I use various software for improving testing and refactoring experience. These are WatiN, QUnit, Moq, Resharper, xunit, log4net, vsvim and many more. My favorite books are "Pragmatic Programmer", "Code Complete", "CLR via C#", "Design Patterns", the ones by M. Fowler and other.

    Barbados - Last active: 06/06/2010 - Tests: 2

    Over the last 6 years I've developed a wide range of desktop application using DevExpress UI, Infragistics UI and SQL Server. For the last 3 years I've preferably taken part in financial desktop projects (not as a freelancer) and have dealt with trading market data, securities, equities etc. But of course my interests are not financial apps limited. I also have experience in the following areas: Math, LINQ, OOP, Dinosaurs API, files parsing. So I'm: 1) a serious developer; 2) always do my best to satisfy all customers' requirements; 3) opened for interesting and creative work; 4) used to work under a deadline pressure
