Welcome my website! This is a space where I share data analysis examples and projects I've been working on. I write articles as part of my own learning process — explaining a concept is often the best way to truly understand it. The goal is to publish short stories and to show the data analysis behind the numbers. I welcome any feedback, comments, or tips you might have.
About me
Hello! I’m Jelmer, and I enjoy working with people to make processes more efficient. I am passionate about working with people to make processes more efficient. I ask myself: How can we improve the current (technical) business process? My approach is to visualize the current process, breaking it down into independent steps and lastly to focus on simplifying it. I believe innovation extends latest technology; it requires the active involvement of all stakeholders. When everybody is motivated to contribute, significant progress can be made. I am always open for a coffee to discuss opportunities!
