Gerbrand was een enthousiaste deelnemer aan de cursus. Het is tekenend dat hij een paar maanden na Aanpakken voor Aanstaande Vaders nog zó enthousiast is. Dankzij deelnemers als Gerbrand zijn de cursus-avonden een succes!

Gerbrand is a excellent developer, he can quickly learn new technologies and apply them. Gebrand aims for better architecture and solution without losing the business focus. Beside of being a excellent developer he is also a great colleague to work with, someone you can count on.
