Nah, I'm not insulted. I wouldn't believe someone, either, if they didn't have any previous work to show for it.
I have been programming since I was in...I dunno, 7th grade? I started off with javascript and later moved on to Java. After about half a year of learning Java, I took a break from programming until about two years ago, when I started learning C++ and picked up Java again. I studied that off and on for a little while and then switched to C# a year ago.
As for the programs I've made, I made an android benchmarking program using Java, but I have no idea where it is. My first application (and the one I'm most proud of) is a PC game. It is meant as a project for myself to learn C#. The version I have (that has not been released) is much more complicated than the one that I have ready for public view. I can post the current beta if you'd like, but it's not nearly as impressive as the build I'm working on right now.
All other stuff is just testing random functions, some programs putting them together to make useless applications. It's practice for when I actually make an application (such as this one).
