[3][4][5] [6] Managed by Pedro Bologna and promoted by Georgina Rivero, Moneo was, as of 2024, the WBA's and WBC's interim women's world lightweight champion.
Moneo made her professional debut on October 14, 2018, defeating the much more experienced Brazilian fighter Amanda Lopes at the Club Coetc in Montevideo by a four-round unanimous decision.
[2] Moneo's next contest after the Lopes rematch saw her debut at the famous Palacio Peñarol in Montevideo as part of a program promoted by Argentine boxing promoter Sampson Lewkowicz that also marked her first time showcased on TyC Sports' Saturday nights television boxing series, Boxeo de Primera, when Moneo boxed Argentine Estefania Alaniz, beating the 4 wins, 2 losses and one draw (tie) fighter by a six-round unanimous decision despite having one point deducted by referee Alejandro Velazquez Torres in round five.
[2] Moneo had a rematch with Estefania Alaniz, by then 5-5-1, with Moneo's WBA Fedelatin lightweight belt on the line, on February 26, 2022, at the Estadio Municipal Hector Gallucci in San Lorenzo, Santa Fe, and she repeated her win over Alaniz by beating her by a wide, unanimous ten-rounds decision with scores of 100-84, 100-89 and 99-88.5 for the Uruguayan (at that time in Argentine boxing, unlike boxing in other countries, judges were allowed to give competitors half a point on rounds) [7] who, with her victory, retained the Fedelatin championship.
[9] On December 15, 2023, Moneo fought for, and won, the WBC's vacant interim women's world lightweight title by outpointing Bolivia's Lizbeth Crespo by unanimous decision after ten rounds, at the Luna Park Stadium in Buenos Aires, in a contest which was televised across the Americas on TyC Sports' Boxeo de Primera television show.
[10] In July 2024, it was announced Moneo would fight Caroline Dubois for the interim WBC women's lightweight world title at Oakwell Stadium in Barnsley, England, on 3 August that year.
