I have worked in .NET technologies since 2010, through various tech such as ASP.NET, Entity Framework, SignalR, Web API and the new .NET Core technologies. The recent years I'm focusing on SignalR and Web API, however I can work really well with ASP.NET, both MVC and Webform. So my skills are really suit your requirement.
