Stamp began training in Muay Thai at the age of five, initially to stand up to bullying at her village school in Rayong Province. She achieved her first knockout at just six years old with a knee technique and went on to become a stadium champion and a two-time champion of Eastern Thailand. As a teenager, she was forced to take an eight-year break because there were hardly any opportunities for women to compete in Muay Thai at the time.
At eighteen, she moved to the renowned Fairtex Training Center in Pattaya, where she also began training in Brazilian Jiu-Jitsu under Jason Burnworth alongside her Muay Thai—a discipline in which she won gold at the Siam Cup in 2019 and eventually earned a purple belt. Her entry into ONE Championship was remarkably fast: on October 6, 2018, she defeated Kai Ting Chuang for the ONE Atomweight Kickboxing title, and on February 22, 2019, she also captured the Muay Thai World Championship. This made her a two-time world champion in two different combat sports by the age of 21.
Her MMA journey began in parallel. On July 19, 2018, she knocked out Rashi Shinde with a head kick after just 19 seconds at ONE Warrior Series, earning her a ONE contract. After a series of victories in the 2021 Atomweight Grand Prix—with an armbar submission against Ritu Phogat as the highlight—she won the tournament championship in December 2021. On March 26, 2022, she lost a title fight against Angela Lee by submission via choke, but on September 30, 2023, she finally captured the ONE Women’s Atomweight MMA World Championship with a TKO victory over Ham Seo Hee. This made her the first-ever three-sport world champion in ONE Championship history.
In May 2025, she had to relinquish her MMA title following complications during her recovery from knee surgery. After a gradual return through Muay Thai, including a bout against Cynthia Flores in mid-2026, she defeated American Selina “Teep Queen” Flores by split decision at ONE Fight Night 47 on September 4, 2026. She subsequently stated that she wanted to resume her MMA career, with the ambition of reclaiming her former title.
