He supported us with the usability and design aspects of specific user applications, as well as with the redesign of our platform. Some of the methods he utilized were User Testing, Design Thinking and Expert Reviews. His feedback was always based on his profound expertise, perfectly adapted to our context. His structure and documentation was very specific and allowed us to directly integrate his findings into our development. Bart-Jan thought ahead of implementation challenges and presented different approaches to cope with them. Besides summative evaluations, he made significant contributions within our creative processes. He has a very good eye for GUI design solutions that go along with his usability improvements. All of his services were on the highest professional level. They were supported by his longtime experiences from working for and with large companies, clients and users -- including, but not limited to, seniors users. On my daily work as a software developer, his usability advice has left a lasting impression. Also, Bart-Jan is a very nice and open-minded person that is always fun and interesting to chat with." and "Bart-Jan is detail-oriented, organized, and a strategic thinker. We collaborated on an idea for a start-up focusing on improving interactive technologies for aging adults, where I found Bart-Jan to be a good leader and an enjoyable colleague. His organizational skills help provide a high level of useful information for his clients, his communication is professional, and his commitment to his work is motivational. I highly recommend working with Bart-Jan and would be happy to do so again in the future."
