My name is Sandie and Kasei Vallis is my design studio. Kasei Vallis is the name of a valley on Mars, and I love science-fiction and anticipation books. So that's why.

I'm a french freelance art director, currently living in Paris, France, but I speak good english (even with a strong accent) and fluent italian. I love colors, lights, reading, talking to people, animated gifs and travelling. I've lived abroad sometimes (mostly in sunny areas...) and the summer is my favorite season. My italian roots have made me a social person and I like to work within a team or in relation with other people.

Sometimes I participate in nice projects with my friends (other than design). One of the bests ones is D12ouze.

During the Paris Lockdown, I've been drawing and playing for Mondes Sauvages and their HOME project.

The very nice picture of myself that I love has been taken by the talented Pierre Prospero.
