UX Audit for new SaaS Project

Worked with Jonas before and he again met all expectations on a great UX professional! Added more cool and value adding ideas to our concept and prototypes. For Jonas UX is really more than UI design - he really puts himself into the customer's shoes and comes up with ideas from the user perspective to enhance the user experience as a whole and in the details. I am sure we will continue to work together in the future!
