My full name is Antonio Carlos de Andrade Campello Junior. It is 52 characters long (including spaces), a fact that has caused me some troubles with immigration. My Ërdos number is 4 (via Sueli, looking forward to increasing it) and my average typing speed is 106 wpm.

I like rock'n roll, modern art and Esporte Clube Bahia. I was born in Salvador - Bahia, one of the most interesting cities of the world.
