I have earned a Master of Science degree at the Delft University of Technology at the faculty of Electrical Engineering in 1997, worked as Technical Sales Consultant at Lucent Technologies until 2001, I was a freelance Technical Trainer/Instructor for 6 years flying all over the world until 2007, then I started a ISP company and settled down, and now I have 2 beautiful daughters. Since 2015 I have transformed myself to a product developer and inventor, with now 2 patents to my name. Since 2020 my focus is all software development, with experience from Linux kernel modules, to perl/python scripts and daemons, to full-stack web applications using node/ruby-rails/python-django backend and REST-JSON API to the front-end.
