Software Engineer based near Amsterdam, with 19+ years of experience translating customer needs into practical solutions. My specialty is system integration: connecting low-code platforms, legacy systems, and modern APIs into something coherent. At home in both low-code (deepest specialty: FileMaker, currently broadening into other platforms) and full-stack development in PHP and Ruby on Rails. Co-founded two ventures along the way.
