    Experienced LAMP & .NET (C#/VB) with SQL/MySql plus Frontend

    United States - Last active: 02/17/2014 - Tests: 1 - Portfolio: 2

    I am a web developer with a strong background in LAMP & .NET. I have 5+ years dealing with PHP in the apache environment running on many different distros of Linux: Redhat, CentOS, and Ubuntu. I am currently employed as a .NET programmer working with both C# and VB. Having both Open Source and Microsoft technologies in my background allows me to be non-biased and take the most logically approach to solving custom solutions. As for databases, I am experience with SQL Server and MySql. While I do have heavy backend experience, I don't limit myself to only backend development. I also have a strong frontend mindset. I know javascript as a base language and have also used jQuery, BackboneJS, RequireJS and many other frameworks. Knowing the technologies that I know isn't what I believe makes me valuable as a programmer. I am well versed in the type of applications I can develop. I have plenty of experience in developing many different business applications. Ecommerce, CMS, User Management, Booking Systems, Invoice/Billing Systems, and many more.
