[1] Joe competed in a breaststroke double at the 2000 Summer Olympics in Sydney.

[2][3] In the 100 m breaststroke, held on the first day of the Games, Joe challenged seven other swimmers in heat four, including two-time Olympians Valērijs Kalmikovs of Latvia and Arsenio López of Puerto Rico.

He earned a fifth spot and forty-fifth overall by almost seven-tenths of a second (0.70) behind joint winners Kalmikovs and Lopez in 1:04.71, worthy enough for a personal best.

He set a new South Korean record of 2:19.16 to overhaul a 2:20 barrier and to touch the wall first in heat three.
