After compiling an amateur record of 90 wins and 5 losses, Kalambay turned professional in 1980. In 1985, he was outpointed over ten rounds by Duane Thomas in Atlantic City, New Jersey, United States. Kalambay won the Italian middleweight title by defeating Giovanni De Marco by split decision, then lost to former WBA light middleweight champion Ayub Kalule by split decision over twelve rounds for the European middleweight title.

In his next fight, Kalambay defeated future three-weight world champion Iran Barkley by unanimous decision over fifteen rounds to win the vacant WBA middleweight title. He made three successful title defenses, including an upset unanimous decision win over Mike McCallum, the undefeated former WBA light middleweight champion.

In March 1989, at the Hilton Hotel, Las Vegas, Nevada, United States, he boxed undefeated IBF middleweight champion Michael Nunn, being stripped of the WBA belt prior to the bout.
