Alongside the production of original music, which is part of his nine self-produced solo albums, Sallaberry has always been involved in some way with music score, sometimes working as a collaborator on television productions (TV Cultura, Brazilian TV channel) and radio (97FM radio station), and sometimes producing his own scores. 

In 2023, Sallaberry dedicated himself more actively to composing score, with the aim of providing material for documentaries and TV programs, as well as for cinema.

In January 2025, Sallaberry began producing soundtracks (film/tv score) for a wide range of television programs for Rede Globo. The Grupo Globo is a Brazilian media and communications conglomerate, with a wide range of products and services, including television, radio, internet, cinema and print. Some of the main brands and companies that are part of the group include TV Globo, G1, GloboPlay, Globosat, O Globo, Rádio Globo and Som Livre. 

TV Globo has been described as the second-largest commercial TV network in the world, following the American ABC Television Network. This Brazilian media conglomerate is the largest commercial network in South America and the world's largest producer of telenovelas.
