JDM began his journey in combat sports early, starting boxing training at the age of 13. This foundation is evident in his striking, which features crisp combinations, excellent head movement, and devastating knockout power—12 of his 18 professional wins have come by knockout or TKO. Before dedicating himself fully to MMA, he also had a significant involvement in rugby, which likely contributed to his overall athleticism and conditioning.

Unlike many fighters who peak in their early 30s, Della Maddalena reached the top echelons of the welterweight division before turning 30. His entry into the UFC came via the Contender Series, and he quickly rattled off a string of impressive performances, earning multiple performance bonuses and building massive momentum.

His ability to adapt and learn is a hallmark of his young career. Training out of Western Australia, JDM balances his demanding schedule with family life, often citing his role as a father as a key motivator. This focus and dedication have allowed him to maintain a high level of performance, making him a consistent threat in a division known for its deep talent pool, which includes names like Belal Muhammad and Kamaru Usman.
