Michał Piotrowski is an „accidental” programmer – because what can have of shared master's degree from the political science and contributing (in PHP, horror of horrors!) of community portal?

He is meeting recesses of the Java in the free time which still he is lacking, (with the special liking for JEE), and is publishing effects of his progress on the blog available at the address http://chlebik.wordpress.com
