Toxcct is an electronics guy who felt in love with programming at the age of 10 when he discovered C to play with Texas-Instruments calculators.

Few years later, he discovered "The C++ Language" from Bjarne Stroustrup ; a true transformation in his life.

Now, toxcct is experiencing the Web by developing Siebel CRM Applications for a living. He also respects very much the Web Standards (YES, a HTML/CSS code MUST validate !), and plays around with HTML/CSS/Javascript/Ajax/PHP and such.

_____

After four years of services as a Codeproject MVP, toxcct is now taking some distance as he doesn't like how things are going on the forums. he particularly doesn't accept how some totally ignorant people got the MVP Reward by only being arrogant and insulting while replying on the technical forums.
