GitHub Sponsors Profile

I'm a Software/Mechanical Engineer with experience in Fluid dynamics, Soil mechanics, Aluminum-/Plastic extrusion, Computer Vision, FDM slicers and C++/Python/LaTeX. My interests and expertise lie in geometric algorithms, computer vision and simulation. As a fanboy of open-source all my repositories are available to the public. I don't believe in keeping knowledge for yourself. You only gain that edge by truly understanding and applying that knowledge.
Open source contributions
I'm currently employed by Ultimaker, working as a Software developer on Cura, before that I worked as a Mechatronic Engineer developing new concepts and ideas for the hot-end. My knowledge about 3D printing is extensive and I'm an active member of the community. Helping out and investing time in others, the same as others invested in me.
In my free time I have developed:

ElevatedBeatsnSlices A Cura plugin that plays elevator musak while you wait on your model being sliced
CuraEngine Plugin pattern A CuraEngine plugin which implements additional infill patterns
PIDcircuitTikZ, a LaTeX TiKz extension which allows you to draw Process and Instrumentation Diagrams with LaTeX.
Home Assistant Ultimaker component, a Home Assistant extension for connecting your Ultimaker printers to your Domotica server.
MechMat, a Python package for the definition of materials used during mechanical engineering calculations
MechCite, a Python package for source citations when a function is used (using BibTex)
MechReo, a Python rheology toolbox
pyDewesoft, a Python package for reading and manipulation of stored DeweSoft measurement files
RazorIMUFirmware, a highspeed and accurate C++ Firmware for the Razor IMU
Dissim, a Discrete Dynamic System Simulation library written in C++
ohCaptain, a generic library written in C++ for embedded devices (such as the Raspberry Pi or Beaglebone) which implements Artificial Intelligence for (under)water vessels.
VisionSoilAnalyzer, a soil analyzer which uses the optical properties, to determine, mineral content, shape and Particle Size Distribution.
