I met Yves when he organized a session for the European Summer School on Agile Programming, of which I was an organizer. Yves’ session was about how to handle leadership in a team; therefore it was highly relevant for Agile programmers, who aspire to work in a self-organizing team. Yves has a skill of inventing games for the purpose of teaching; or to be more precise, he invents an environment where the participant learns by exploring and experiencing a subject. This is a powerful way of learning.
Yves is serious and dedicated to what he does. He is creative, original, careful and competent. He is committed to facilitating a positive improvement in the people he works with, and likewise he is committed to improving the way he works. I highly recommend hiring Yves for all work concerning team building.
