In 1990 he started collaborating with fellow Croatian Darko Macan on Albert the Butler, a series of short horror stories published in Croatia and Germany.

Macan was the writer on most of the comics Sudžuka did in Croatia (some of those were later collected in a single volume called Sudžukice),[2] including Svebor & Plamena, a teenage soap-opera which won him the award for Best Realistic Comic in Croatia in 1997.

From 2004 to 2007 Sudžuka was a regular fill-in artist on Brian K. Vaughan and Pia Guerra's Y: The Last Man.

In 2011 he completed A.D.D., a graphic novel for Vertigo written by Douglas Rushkoff and published in January 2012.

In 2013 he worked on the series Ghosted with Joshua Williamson for Skybound, and as fill-in artist on Brian Azzarello and Cliff Chiang's Wonder Woman.
