With Rein you get a top performer! We worked together on several projects and I look back on that with pleasure. Rein is analytical and combines that with creativity. He is technically strong, and can transfer this well to others. He knows how to lift people to a higher level. In short, of great value to an organization.

I would highly recommend Rein Velt to anyone who needs more than "just a programmer". In our experience, Rein is able to understand and extrapolate on a rudimentary business case and is a valuable partner in strategic and operational technical issues. The extra mile seems standard for Rein.
