David Arumi was born in Barcelona in 1983. His fondness for drawing and art led him to study Art Grafic at Escola Joso in Barcelona. He completed his postgraduate studies on illustration for children's publications and creative illustration at Escola Eina. Soon after he finished his illustration book in 2006, different Spanish publishers began to approach him.

Since then, David has been working as a freelance illustrator for several publishers, magazines and advertising agencies. He usually works digitally, drawing and painting directly on the screen with his Wacom Cintiq. He can gladly say that his hobby has become his job and he hopes that it will last forever.
