I've been coding in C# for about 5 years. I know how to do most everything in that, and I've just started using X-Code and Objective-C recently for iOS dev. I also do Java (mainly Android dev) and ActionScript 3 for Flash game development. I also know a lot of XNA, and I've dabbled in C++ and VB.NET. I'm also proficient in HTML (5 or XHTML) and CSS3, SQL, MySQL, PHP, and Javascript.
