    Ukraine - Last active: 8 days ago - Tests: 5

    Hi. My name is Oleh. I love to solve problems and create architectures that prevent them. I'm driven, if not obsessed, by solving different technical challenges. When I don't have one to solve at work, I invent them on the side to keep my development skills sharp and give myself a reason to get out of bed, or even sometimes stay up all night. I have good experience in: - Desktop development on WPF and Windows Forms; - Web development on ASP.NET/ASP.NET MVC; - Metro development (Windows 8 apps); - Have good database knowledge (SQL Server, MySQL, SQLite etc) and ORM (Entity Framework); Feel free to contact me if you need help implementing your next idea using cutting-edge technology.
