Live Teaching

I love sharing my expertise with people and helping them acquire new skills. My teaching experience includes lecturing Computer Science in higher education (HBO). Some of my current activities:

  • In 2017 I've started collaborating with several other trainers. We're working together as ColTrain, and we will be focusing mainly on Data Science and related topics.
  • I will be teaching Python for Global Knowledge at various times during 2018.
  • Another really cool thing I do for Global Knowledge is a course called Automation with Python, which is very useful, for example, for system and network administrators.
  • In collaboration with the IT Performance House, I am teaching Data Science, Java and Web Development traineeships to young professionals for Working Talent, Young Capital and IT Academy Noord Nederland.
  • And in the meantime I'm probably working on another online course..

You can of course always contact me with questions on courses. I'll be happy to offer a custom course based on your needs.


I'm a senior developer and Scrum master and available for short-term development projects. My main experience is in Java and Python. For more information about my background, please check my LinkedIn profile, or contact me directly.
