Juan was an amateur boxer and a hopeful of the Olympics, however, he lost in the qualifiers. He immediately went to professional boxing with his family as his seconds, including his former world ranking uncle as his chief trainer. After his professional debut, he had a sixteen winning streak with fourteen knockouts and became the WBA lightweight world champion. In his second title defence, he was defeated by an attack to the body and lost his title.

Juan uses exchanges, counting on his strength to win out on them. He favours using his left hook as his knockout punch, as that was used for 80% of his knockouts. His lefts come out in abnormal angles, however, his fist position remains the same. His punches aim both high and low, making it difficult for one to block. He uses a high guard that is higher than his jaw, making it harder to break.
Due to his high guard, he leaves his body open for attacks.
