[1] He represented his nation Georgia in two editions of the Olympic Games (2000 and 2004), and nearly ended his sporting campaign with a blistering bronze medal effort at the 2005 European Championships in Varna, Bulgaria.

Giorgadze made his official debut at the 2000 Summer Olympics in Sydney, where he competed in the men's super heavyweight division (130 kg).

He lost two straight matches each to Sweden's Eddy Bengtsson and Belarus' Dmitry Debelka, who later claimed a bronze medal at the end of the tournament in the prelim pool, finishing last out of twenty wrestlers in the overall standings.

[3][4] Since his previous Games, Giorgadze could not recover a setback from his former rival Bengtsson on the opening bout, but managed to break a 2–2 draw and score a single triumph over Kazakhstan's Georgiy Tsurtsumia.

Giorgadze's devised game plan did not effectively accomplish, as he was haplessly pinned by the host nation's Xenofon Koutsioumpas and Sweden's Eddy Bengtsson without receiving a single point, finishing third in the prelim pool and fifteenth in the overall rankings.
