I've been working as a freelancer developing iOS applications since 2008. I have developed about 30 iOS apps from scratch (ranging from games to business applications), and worked on many more. I am familiar with most aspects of iOS programming, including UIKit, CoreAnimation, OpenGL, GameKit, IAPs, CoreText, GCD, networking.

I've been programming in C since I was a kid. I started my professional career programming Palm PDAs in C/C++ in 2001 and moved on to game programming on a variety of platforms. Since then I switched my primary programming language to Objective-C, but C knowledge always comes handy.

In the distant past I programmed C++ on a variety of (gaming) platforms ranging from Palm to PlayStation2. I haven't had much exposure to it since then but occasionally C++ knowledge comes handy when interfacing native libraries and such.

I've used Python numerous times for scripting purposes, custom gamedev tools and solving math problems.
