Hello
I understand that you are looking for a developer to develop your existing C# application.
We would like to know more about this application for better understanding. What type of changes do you want on your existing application?
We are a team of software developers who work on Microsoft technology stack like C#.NET, ASP.NET, VB.NET, SQL Server, WPF, WCF, SharePoint, MVC etc.
Other skills- HTML5, CSS, JQuery, Bootstrap, JavaScript.
We can schedule a chat/call for further discussion.
Thanks,
Smita
