He debuted in the Yugoslav comic book industry in 1982 with the series Elmer Jones (Serbian Cyrillic: Елмер Џонс), a Leonesque western scripted by Dragan Savić.
But Guerra received true recognition as one of the best Western authors in Yugoslavia in 1985-1986 when he published “Texan Riders” in Spunk novosti and Stripoteka.
He then shifted his focus to commercial work, including advertisements, design, covers, and animation storyboards.
Guéra collaborated with Patrick Cothias on 'Le Lièvre de Mars', a series previously drawn by Antonio Parras for Glénat in France.
In 2019, Guerra did an episode of Tex Willer titled "The Man with Golden Pistols" for the Italian publisher Bonelli comics.
