I'm a self-motivated man who loves very much about programming.
I do always learn before I invent so that my colleagues don't have to deal with "genius" code.
Programming skills are like wands for wizards, they can help build many amazing things in a fantastic way.
But unlike magic, programming is about simplicity, readability.
And that's what I do, build awesome(hopefully) things with simple readable code.
