Hello Sir,
I have 10+ years of experience in software development, please have look at the projects/certifications/ratings and most important the completion rate of projects that I have completed here which proves that I am a genuine developer.
I have done this many times before. I have some sample ready for demonstration if you like to take a look. I understand your requirement very well and can do it as per your expectations. And I can start working on this immediately.
I am expert in ASP.Net, C#, VB.Net, MVC REST/Web API, AngularJS, javascript/jquery, css, html, SQL Server, php so not to worry about anything.
Let me know if you are interested so that we can discuss in more detail.
Thanks,
Ninad
