About me

I've been interested in programming more or less since elementary school. During this period that I started writing my first scripts using the LUA language. Then it was time to get to know XML, HTML, PHP and C++. I believe that this is a way to create your own world, according to your own rules.
In my spare time, I like to play the immortal CS, go to the tennis court, dip in the pool or just drink a beer :)
