Using an explorative approach, Bastien develops design solutions that are always based on in-depth research into the content. His work is characterized by the coherent and intuitive structuring of information through the predominant usage of typography and imagery. A clear and reduced expression, typographic expertise as well as the early consideration of technical production issues determine his design process. Working collaboratively, his experience ranges from print to digital media, which is manifested in the conception and development of diverse projects in the field of visual communication and includes the design of visual identities, websites, typefaces, books and posters.

In addition to his studies in visual communication, he works as a freelance graphic designer with clients such as the Zurich based fashion label Luca Xavier Tanner or the Zurich University of the Arts (ZHdK).
