Apart from above, I have thorough knowledge of Back end, and I have studied about databases in quite a detail. I have worked with SQL Server 2008, 2012, SqlLite, Access, Oracle etc. Currently I am working on Azure Sql Server.

In a Nutshell, I can give a complete application for Windows or Web with above mentioned technologies, please feel free to contact me or let me have a small hand in contribution to your big ideas.
