Hi,
I understood your high level requirement. I have worked on similar project before. If you are interested then i can show you demo on teamviewer.
I have 6+ years experience in software development and customization using wide range of Microsoft technologies (C#, ASP.NET, MVC,WPF, Window form, Sql Databases, Azure, Sync framework etc.) and few open source like PHP,Java,JabbR. Since i have previous experience in such applications, so I think it will help in this project, if selected.
About my previous work, you can visit my profile to see feedback from previous employer.
Let me know, If you find me suitable for this project and share complete details. If you want more details, we can discuss over chat/ skype.
Regards,
Shashi Bhushan
