I am an independent software developer currently writing apps for iOS. I've been writing software for over 30 years now, mostly for various Apple products such as Mac (and Apple ][ early on) but also for Windows, embedded systems and even custom OSes. I write in a wide variety of languages, including many flavors of machine/assembly, C/C++ and Objective C. I think the only language I haven't enjoyed learning and using over the years is HTML/Javascript ;)
