Zaldi, being born with a gifted hand at drawing, was always begged by people close to him to draw them. He is also good in making caricatures. He completed his Industrial Design Major at the University of Santo Tomas, or UST, in Manila. He started working as an artist of Fil-Cartoons, and also engaged in sideline drawing jobs. After a few years, Walt Disney Australia offered him a job as a cleanup artist. He gladly accepted it, working his way to his current job as an animator.
