Hi, my name is Maarten!

IT consultant 👨🏻‍💻, trainer 🧑🏻‍🏫 and public speaker 🗣️ based in the Netherlands.

👨🏻‍💻 I help organisations shape solution and software architecture for their business problems. I’ve consulted many large enterprises in the Netherlands, mostly in the financial domain and public sector.

🧑🏻‍🏫 I teach solution architecture, software architecture and their role in modern IT projects. I also teach various Java and JVM-related topics, such as testing, the Java platform and Apache Maven.

🗣️ As a speaker, I frequently speak on various developer conferences and meetups across Europe and Northern America. My talks mostly cover topics I’m passionate about: open source and the Java ecosystem.

Because of my contributions to and support of the Java ecosystem, I am recognised as a 🏆 Java Champion and awarded an ♠️ Oracle ACE Pro for seven consecutive years.
