Hi, I'm a software/database developer with more than 30 years of experience, at least twenty of them employed by international organizations, including the United Nations. I have expertise with MS-SQL (T-SQL), as well as the .NET framework, including designing/devloping with ASP.NET and MVC 3. To be fair, have not done any work with MVC 4, but I don't think this would me much a problem. I'm currently retired, so I can dedicate your project the time it may require.
Although I think I fit most of your requirements, you are not specific enough about your project, so my offer is basically for a month of full-time work for you.
If you think you may be interested in my services, please open a chat. I can provide a CV (for you to check references and experience) and we can further discuss my qualifications and/or your requirements.
Best regards,
Marco García
