At the age of 14, he began training in Brazilian Jiu-Jitsu, following his father and sister. This marked a turning point in his life, as he quickly developed a passion for the martial art.

Following this victory, he received his black belt on the podium, signifying his rapid ascent in the sport. His career in Jiu-Jitsu saw him accumulate 17 BJJ World Championship titles, with six of these being in the openweight category, a record that he still holds.
In July 2020, Almeida made a transition from Brazilian Jiu-Jitsu to mixed martial arts, signing with ONE Championship. He has since trained with teams such as American Kickboxing Academy and American Top Team. His MMA debut was originally delayed due to a knee injury in August 2020. He eventually made his debut in September 2021 against Anderson Silva, securing a submission victory in the first round. He continued his winning streak in ONE Championship, showcasing his grappling skills with four first-round finishes against opponents such as Kang Ji-won, Simon Carson, and Kirill Grishenko.
