He then went to study luthiery from 2001 to 2004 in Cremona, Italy at the "Antonio Stradivari" (IPIALL) luthiery school. After graduating he did an internship with Lorenzo Frignani, violin and guitar maker in Modena, Italy. Here he dedicated himself to learning the construction, restoration and repair of various modern and historical stringed instruments. Since 2007 he has been working as a violin and guitar maker in Switzerland, where he opened his own studio in Wattwil in 2010.

The construction is based on traditional knowledge, which he is constantly developing with modern knowledge of acoustics.
