Joep wandered into testing in 2006. Two years later he discovered context-driven and realised that testing is actually not that bad a fit for a philosopher. In 2015 he joined Mendix, one reason being that he wanted to increase his technical skills. Since then he's become more and more involved in automation, while also taking on the roles of scrum master and team lead.
Somewhere along his journey (some say it was 2013) he started speaking at conferences and joined DEWT. Outside of work his thoughts tend to revolve around coffee, fountain pens and bouldering.
