Efa was born in Sabadell, Spain. At the age of 16 he quit his studies to enjoy... life. In 1995 he created his first fanzine with some friends: Realitat Virtual. From there, he worked in a cartoon studio as well as working as a freelance illustrator. He entered the world of comics in 2001, in collaboration with the writer Toni Termens, with the series "Les Icariades" (3 volumes and a complete edition published by Paquet). In 2002 he began his solo series - "Rodiguez" (two volumes also published by Paquet). In 2004 (still with Paquet) he published "L'Âme du vin", a very personal album that he wrote and illustrated. Between 2007 and 2009, he illustrated and colored the series "Kia Ora" (3 volumes with Vents d'Ouest, script by Olivier Jouvray and Virginia Ollagnier). In 2008 he joined the "Alter Ego" team, joining forces with Mathieu Reynès, a previous contact from Paquet.
