In 2024 I completed my Masters’ Degree. My research topic was BiDE, a language and architecture for the creation of bidirectional diagrammatic editors. In essence a way to modify program text using diagrams and text at the same time, allowing stakeholders of different backgrounds to work on the same system at the same time. I worked on this thesis with Bastiaan Heeren (Open Universiteit) and Jurgen Vinju (Centrum Wiskunde en Informatica).
In my spare time I love to explore the cutting edge of software engineering, exploring new languages such as Rust, Clojure and Golang in combination with Large Language Models and their novel applications.
