From there he learned to transfer his experiences with these materials to designing and building the first pieces for his home. He began to receive requests from friends and started short production runs.

In 2008, after a sabbatical spent in the USA, he left the practice of medicine, only to follow the design product. He presented G_BICYCLE, a demountable bicycle project, in production in 2015. In 2018 he presented ANOTHER LIFE, an easy way to recycle plastic bottles and turn them into showers and showerheads. Since then he projects for Alpes Inox, Agape, Boffi, Foscarini, Dimensione Disegno, Cea, Cesana and others, and recently Pamar. With Kaa project he won Edida 2005, Design Plus Material Vision 2005 and Designpreis 2007. In 2006 the estinguisher Fire for Boffi won the Wallpaper Award. Guendalina is in the Design Index 2010.
