Cuarto made his professional boxing debut on June 28, 2014, securing a four-round unanimous decision (UD) victory against Rodante Suacasa at the Almendras Gym in Davao City, Philippines. With a record of 15–1–1 (9 KOs) under his belt, he faced Clyde Azarcon and clinched the vacant WBO Oriental mini-flyweight title through a twelve-round UD at the Gaisano Mall of Davao, Philippines.
IBF mini-flyweight champion The Taduran Contests After engaging in four more bouts, consisting of two wins, one loss, and a draw, Cuarto stepped up to challenge IBF mini-flyweight champion Pedro Taduran on February 27, 2021, at the Bula Gym in General Santos, Philippines. Originally set for January, the fight had to be postponed due to the ongoing COVID-19 pandemic. Cuarto utilized a strategic boxing approach, countering Taduran’s aggressive stance, and emerged victorious via UD after twelve rounds. The judges’ scores were unanimous at 115–113 in favor of Cuarto, granting him his first world title.
Cuarto confronted Taduran once again in an immediate rematch for his initial IBF mini-flyweight title defense. The rematch was initially scheduled for January 29, 2022, in Digos, Philippines, but was later rescheduled for February 6. Cuarto held onto his title after the bout was stopped in the seventh round due to a cut on Taduran’s forehead resulting from an accidental clash of heads in the sixth round. Cuarto was awarded a majority decision victory, with two judges scoring the fight 65–64 and 66–64 in his favor, while the third judge recorded it as a 65–65 draw. Notably, Cuarto downed Taduran in the second and sixth rounds and was penalized a point in the third round for an intentional headbutt.
Cuatro vs. Valladares Cuatro’s second IBF mini-flyweight title defense was anticipated against Daniel Valladares, a former IBF title challenger, scheduled for May 27, 2022, in Monterrey, Mexico. Despite initial plans, the fight was canceled due to undisclosed reasons but was later rescheduled for July 1, 2022, at the same venue. In the contest, Cuarto lost by split decision. Two judges scored the bout 116–111 and 115–112 in favor of Cuarto, while the third judge recorded it as a 114–113 victory for Cuarto. During the tenth round, Cuarto had a point deducted due to loose glove tape.
Post Title Reign Following his title reign, Cuarto confronted fellow countryman Dexter Alimento on December 23, 2022, at the Baliok Gym in Davao City, Philippines. Cuarto triumphed with a second-round knockout, as Alimento failed to rise from the canvas within the ten-count after taking a liver shot. Following this victory, Cuarto received an order from the IBF to face Ginjiro Shigeoka for the interim mini-flyweight championship, as the reigning champion, Daniel Valladares, was sidelined due to an injury. The fight took place on April 16, 2023, at the Yoyogi National Gymnasium in Tokyo, Japan, where Cuarto suffered a ninth-round knockout loss.
