Disco was a mostly lower card wrestler during his six-year tenure with WCW, but achieved some success in the form of championships. He was a 1 time Cruiserweight Champion, 2 time Television Champion and 1 time World Tag Team Champion with Alex Wright, as part of the tag team Boogie Knights.
Gillbertti signed a contract with WCW in 1995 and debuted later that same year. He gradually rose to mid-card status as a tweener, with his gimmick being that he would forget how to apply his finishing hold, a standing figure-four leglock. Often, he would bring a cheat sheet with a diagram on how to apply the hold to the ring. He mostly competed in WCW's mid-card division shows including Saturday Night, Main Event and WorldWide. Inferno wrestled on many editions of Main Event before pay-per-view events against superstars such as Joey Maggs and Eddie Guerrero. He also competed on January 23, 1996 edition of Clash of the Champions in a losing effort to Kevin Sullivan. Inferno made his pay-per-view debut at Slamboree 1996: Lord of the Ring in a tag team contest where he teamed up with his future partner Alex Wright against Dick Slater and Earl Robert Eaton.
He feuded with Alex Wright who began dancing before his entrance to mock Disco. The two became arch-dancing-rivals. Disco was booked to win the WCW World Television Championship from Wright on September 22 edition of Nitro. He lost to Jacquelyn at Halloween Havoc 1997. He engaged in a feud with Perry Saturn after losing the Television title to Saturn on November 3 edition of Nitro. Disco lost to Saturn in a rematch at World War 3 1997, before finally regaining the title from Saturn in a rematch on December 8 edition of Nitro for his second WCW World Television Championship. Four weeks later, he dropped the title to Booker T.
After not getting any success, Inferno and Wright split and began focusing on their singles careers again. Inferno started a feud with Juventud Guerrera and defeated him at Halloween Havoc 1998 to become the #1 contender to the Cruiserweight Championship. He earned his title shot later that night against champion Billy Kidman but lost the match. At World War 3 1998, he participated in a three ring, 60-man battle royal with the winner getting a shot at the WCW World Heavyweight Championship at Starrcade 1998 but the battle royal was won by Kevin Nash. Inferno became allied with, and eventually joined the nWo Wolfpac. Around that time, Disco feuded with the likes of Booker T, Konnan, Buff Bagwell and Ernest Miller.
Inferno won the WCW Cruiserweight Championship from Psychosis on October 4, 1999 edition of Nitro. He entered a program with Lash LeRoux and had a successful title defense against LeRoux at Halloween Havoc 1999. He was joined by a new ally Tony Marinara. Inferno dropped the Cruiserweight title to Evan Karagias at Mayhem 1999 after Inferno accidentally attacked Marinara. Marinara joined The Mamalukes (Big Vito and Johnny the Bull) while Disco was joined by LeRoux. At Starrcade 1999, Disco and LeRoux lost to Mamalukes after Disco accidentally attacked LeRoux. Disco aligned with Mamalukes and became an enforcer for the duo.
In spring 2000, Eric Bischoff and Vince Russo rebooted WCW and New Blood was formed. The Mamalukes became members of New Blood and Disco signed with The Mamalukes. However, he left the group and joined Filthy Animals. He called himself Disqo, a hip-hop wannabe. Animals feuded with Misfits in Action and Disco unsuccessfully challenged Lieutenant Loco for the Cruiserweight Championship at The Great American Bash 2000. At New Blood Rising, Disco refereed a fatal four way match for the World Tag Team Championship, which KroniK (Brian Adams and Bryan Clark) won. At Fall Brawl 2000, Filthy Animals fought Natural Born Thrillers to a no contest in an elimination match. During the match, Disco turned on Konnan by hitting him a Chartbuster and began feuding with both Animals and Thrillers.
Disco reunited with both former rival and tag team partner, Alex Wright as Boogie Knights. At Halloween Havoc 2000, they challenged for the World Tag Team Championship in a triangle match but ended up losing the match. They were scheduled to win the WCW World Tag Team Championship at WCW Millennium Final on November 16, but Disqo was legitimately injured. General Rection substituted for Disqo and then won the tag titles for Disqo and Wright. However, they would drop the titles afterwards. Disqo remained with the company until it was purchased by World Wrestling Federation in April 2001.
In 2005, he went back to working the independent circuit in Georgia and Minnesota. He also wrestled for the Southern Wrestling Alliance and Vince Russo's Ring Of Glory.
