Onno Ebbens is a hydrologist and programmer with a passion for teaching. He co-founded MAMBA for Python course (www.mamba-python.nl). During his work as a hydrologist he discovered the benefits of Python for data analysis, modelling, automisation and much more. Being a teacher at heart he decided to bring these benefits to a bigger audience by giving a course for Python beginners. The succes and enthusiasm of this course encouraged him to co-found MAMBA together with Petra Izeboud. Together they created a variety of Python courses for individuals and businesses.
