I am a freelance developer / consultant / data scientist working working mostly with Python, C++ and Javascript in the Jupyter ecosystem. My expertise ranges from fast numerical computation, API design, to 3d visualization. I have a Bachelor in ICT, a Master and PhD in Astronomy and like to code and solve problems.

Feel free to contact me if you want to hire me.
