The towering southpaw built his early record methodically, compiling a 12–0 mark over his first three years as a professional. During that stretch he stepped up against undefeated opposition, including a third-round knockout of Donnie Marshall in February 2019 and a victory over Hector Manuel Zepeda on Showtime’s “ShoBox: The New Generation” card in June 2019.
Fundora’s development continued with a bout against Jamontay Clark for the vacant WBC Youth super welterweight title in August 2019, which ended in a split-decision draw. He then fought on the high-profile Deontay Wilder vs. Tyson Fury II undercard in February 2020, defeating Daniel Lewis by unanimous decision. Subsequent victories over Nathaniel Gallimore and Habib Ahmed in 2020 extended his record and set the stage for title-level opportunities in the super welterweight division.

A scheduled October 2025 defense against Keith Thurman was postponed due to a hand injury Fundora suffered in training, and the bout was later rescheduled for 28 March 2026, at the MGM Grand Garden Arena, where Fundora defeated Thurman by sixth-round TKO.
