He was born in Korea in 1971 and studied Taekwondo and Kung Fu from a young age. He became a stuntman during the late 80s working on many local films and also cross over films with Hong Kong and Taiwan.

But by the mid 90s he was feeling dissatisfied with the Korean martial arts film industry and decided to go to Hong Kong. He auditioned for action legend Sammo Hung Kam-bo, which included sending him footage from the 1994 independent short film The Fight, in which he played the lead villain. Sammo was impressed by Kadet, not only by his high skills in martial arts and acrobatics, but notably, his knowledge and understanding of camerawork; editing; and Hong Kong style action.

Kadet worked on two films as a member of the Sammo Hung Stuntmen's Association, Thunderbolt [1995] and Mr. Nice Guy [1997]. Ironically, his main role as part of Sammo's team was as a stunt double for Jackie Chan Kong-sang of all people. He was the first Korean to do so, this being several years before his juniors Park Hyeon-jin and Lee In-seop would take up this role as members of the JCST. It was a well kept secret, especially with the push of the “Jackie does all his own stunts” mythos. So much so, that most people (except those who worked on the films) didn't know his name and many mistook his doubling to be that of fellow SHSA member Chin Ka-lok.

Although stunt doubling was his main task during his time with the team, Sammo was keen to put as much of Kadet's various skills to use as possible: so aside from doubling for JC for the majority of the fight sequence on top of the pachinko machines in Thunderbolt, plus for JC and several other actors for various scenes throughout Mr. Nice Guy; Sammo also involved Kadet in the design of the action scenes of both films and even selected him to be a stunt driver for the chase sequences in Thunderbolt.
