Some compliments for my work:

Joost delivers maximum result with minimal input. He is an asset to any project.
Carmen Popoviciu
I have such an immense respect for Joost, not just because I think he is an incredibly smart person, but because he is humble about his knowledge and very respectful in his way of sharing it. The thing I find most inspiring about him is the fact that he is able to look beyond what people think they can do and encourage them and guide them into doing it.
