Beyond these credits, his career encompasses a wide range of other voice work. He has voiced characters such as Sapo Toro in Star vs. the Forces of Evil, Professor Homunculus in The Owl House, and roles in series like Amphibia and The Ghost and Molly McGee. His dubbing work also extends to live-action, where he is known as the Latin American Spanish voice for actors like Michael Keaton, notably in the film Birdman, and for characters such as Gus Fring in Breaking Bad and Better Call Saul, and Ezekiel in The Walking Dead.

In addition to his voice acting, De Candia was a prominent locutor and on-air personality for the Argentine television program Bendita for 13 years. In 2020, he relocated from Argentina to Gijón, Spain, where he continues his work in dubbing and voice-over from a home studio he established there.
