Peter Maas is a Chief Technology Officer at Marktplaats. He possess expertise in scrum, java, maven, spring, hibernate and 45 more skills. Colleagues describe him as "I worked with Peter for over 4 years in various capacities and with different levels of direct contact. When working closely with Peter he impresses with his ability to quickly understand the problem area and bring his considerable technical expertise to the table. He is well respected by the engineers that work with him, and he provides technical leadership and authority to give them freedom, but at the same time steer them in the right direction. I have also worked with Peter in more strategic situations where we have not been in such close contact. In these situations Peter is clear on the strategic direction he wants to take, and communicates his work and achievements well. He is quick to collaborate at a strategic level, working across organisational boundaries and aligning teams so that they have a bigger impact by working together." and "Peter is a very technical and talented developer. He has a broad knowledge of Java and the underlying infrastructure. He's not anti-social like most IT people, actually is quite a pleasure to talk and work with him. A real team player!"
