What's the difference

I have been writing code since I first saw an 8-bit home computer in 6th grade. Aside from my main programming language of C++, I have acquired an arsenal of web development skills over the years, but what excites me most these days is iOS and the backend biotopes that support it.

Writing apps from scratch is my passion, but I am not above taking an existing project, whipping it into shape, and turning it from blah to wow!

I delight in making complicated technical concepts understandable…
