Felienne is an assistant professor at Delft University of Technology where she makes software engineering applicable for a broad audience. To that end, she has built an IDE for spreadsheets: smell detection, refactoring, and unit testing tools for Excel. More recently, she has worked on code smells and clone detection in the Scratch programming language for kids. Felienne is one of the founders of Joy of Coding, a one-day developer conference in Rotterdam, The Netherlands, celebrating the love of programming. When not building programs that play board games or card games, she is probably dancing Lindy Hop or killing creeps in a tower defense game.
