"I had the pleasure of working with Jeroen for many years and have rarely found someone as dedicated as him towards the quality of the software he is working on."

Abraham Taherivand / Executive Director, Wikimedia Deutschland
"Jeroen is one of the most productive and passionate developers that I know. Without Jeroen, Wikidata would not have such a rich range of functions and would be built on a less flexible, lower-quality codebase and architecture. I have always appreciated his professional attitude, collegial and reliable manner. He is an absolute win for any team and project!"
