Thaikaew was born on April 13, 1973 into a poor family living in tambon Pak Phraek in Thung Song district, Nakhon Si Thammarat province.
[2] Oley later joined the Kiatbanchong branch in his hometown where he would become teammates with future yodmuay (top fighters) such as Jaroensap, Jaroenthong, and Samranthong.
After knocking out Chanoi Petchnaka and beating Rao Rajanarit on points, he was scouted and hired by Songchai Rattanasuban, the owner of Onesongchai, and began fighting primarily in the Lumpinee Stadium.
Oley's skill and his ability to mix Western boxing techniques with his Muay Thai fighting style resulted in him being compared to Samart Payakaroon as well as Poot Lorlek.
He would employ the use of head movement to dodge punches, redirection of his opponents as they attacked, and, to avoid kicks, he would lean back to the point that his torso would be parallel to the floor as can be seen in his fights against Boonlai Sor.Thanikul or Namkabuan Nongkeepahuyuth.
[2] He won the Lumpinee Junior Bantamweight title (115 lbs/52.16 kg) in his rematch against Boonlai and successfully defended it against "The Top Master" Karuhat Sor.Supawan in a Onesongchai show in New Zealand.
December 1992 to August 1993 was the most significant period of Oley's career as he had a 7-fight winning streak against the best fighters of the featherweight division (126 lbs/57.15 kg) including but not limited to Wangchannoi Sor.Palangchai and Chamuekpet Hapalang.
In his 4th and final boxing fight, he was set to compete for the PABA Super Bantamweight title against Russia's Alexander Pak in his native province of Nakhon Si Thammarat in 1995.
He did not involve himself with combat sports for a long period of time as he was running small family restaurants in his hometown of Thung Song.
