Cruz started his professional career as a letterer for Editora Abril, the Brazilian publishing house, for whom he lettered many Portuguese translations of American comics; then worked as a writer and art assistant for Mil Perigos, a short-lived black and white comics magazine.

At the end of the 1990s, Cruz took a break from working on comic books and returned to Brazil, where he became one of the founders and partners of an art studio/school called Fábrica de Quadrinhos ("Comic Book Factory"; currently named Quanta Academia de Artes).

Still being a Fábrica de Quadrinhos partner, he returned to work for the American market, contributing to Top Cow Productions titles such as The Darkness and Ascension, and Marvel titles like X-Men, Wolverine, and Magneto: Dark Seduction.

In 1999 Cruz gave up his projects in Fábrica de Quadrinhos and returned to work exclusively with comics.

Since 2019 Cruz published more authorial works in Brazil, such as Xampu- Lovely Losers,[4][5] Quaisqualingundum (as writer; art by David Calil), based on songs by composer Adoniran Barbosa, A Irmandade Bege e Os Fabulosos, a parody of X-Men.
