[1] He represented his nation Kazakhstan at the 2008 Summer Olympics, and has won a silver medal in the 200 m freestyle at the 2007 Asian Indoor Games in Macau, China.

[2] Rabota competed for the Kazakh squad in two swimming events at the 2008 Summer Olympics in Beijing.

He posted a time of 2:03.75 to set himself up as the fourth seed headed into the 200 m backstroke final of the Olympic test event in Beijing, and then snatched the 400 m freestyle title with a 3:56.98 at the Kazakhstan Open Championships three months later in Almaty; both of these marks dipped beneath the FINA B-cut.

[3][4] In the 400 m freestyle, Rabota fought off with Argentina's Juan Martín Pereyra for the fourth spot throughout the race, but relegated to fifth and thirty-sixth overall to round out the opening heat in 4:02.16.

[5] Four days later, in the 200 m backstroke, Rabota raced to second on the same heat by 0.78 of a second behind leader Brett Fraser of the Cayman Islands in 2:01.95, but his thirty-third place time in the prelims would not be enough to put him through to the semifinals.
