I studied computer science at the University of Twente on the topics of compiler development. I graduated cum laude with a master degree. I worked some years in academics and with various companies, mostly developing software in C++. Besides having an interest in the subject of developing parsers, I have also done some reverse engineering (of binary and textual formats), helped with the development with some international standard and developed several scripting language one of which is still in use in a commercial available tool for Enterprise Architecture. Besides this, I also have an interest in combinatorics and puzzles. See further github.com/FransFaase and www.iwriteiam.nl
