more about me
I’m strongly focused on delivering not only highly usable digital products, but also design that translates into business results while optimising the user experience.
My motto is that beautiful design is pointless if it’s not functional in the first place.
If you are interested in personality tests this is my type on 16 Personalities .
When I'm not glued to the computer screen I'm usually making pottery, drawing, reparing furniture, taking care of my garden or swimming.
