I've watched him a couple times in the Extreme Fighting Championships. I think he fought two guys in a single night, one of the guys he fought again in another show and lost by armbar.
I think his strong suit seems to be his striking and takedowns. He actually finished one guy fom top position in half guard with a guilotine, which is pretty impressive. The guy is built rather large as well.
Here's a list of his accomplishments I found via wikifighter...
Purple belt in Jiu-Jitsu
Bahia State Jiu-Jitsu Champion
Bahia State Submission Champion
