I have a Bachelor degree in Applied Physics and a Master degree in Biomedical Engineering. I've got 5+ years experience writing papers in English and Dutch. I'm well trained when it comes to technical academia. I've tutored high school and university students in math, physics and English. I daresay I'm equal to most math problems. I can code in Python and know my way around Matlab and Excel. I made my own bookkeeping software (no UI) and for my Master I programmed a SIFT computer vision algorithm. I have 2 years R&D experience in the medical device field, focusing on CAD design & modelling. Though I'm not very good at making "artsy" models, I can make and animate (Blender or Fusion) technical models. I'm interested in writing and am currently writing and editing my own fantasy book. I enjoy reading and writing fantasy fiction, solving sudoku's and riddles. In terms of sports, I'm a Spikeball trainer and player and I do fitness.
