After university Fabienne found herself in the realm of HR and recruiting, namely in aviation engineering, where she gained 9 years of experience. Tech scale-ups have become an integral part of Berlin's culture, much like Currywurst and Kebap, which is why it was a natural decision for her to switch to the world of IT.
