let's work together

Hi, I'm Sven and I am an independent User Experience (UX) researcher/designer based near Antwerp, Belgium. I'm available for (remote) freelancing, workshops and talks, and am always happy to discuss possible fun collaborations. Contact me at sven.charleer@gmail.com or @svencharleer .


User satisfaction is a tough nut to crack. As a UX designer, I research and design experiences that your target audience finds useful, useable, and enjoyable, whether it is a service, an app, data visualizations, or a video game idea. Sure, we can attract users with pretty designs, but it is the user experience design that keeps them coming back. Let me help and guide you through the entire journey from idea to happy users.

My UX Process

The process is as follows: we discuss your idea and scope. We collaboratively explore business and user needs through e.g. brainstorms and surveys, after which I research the state of the art and produce preliminary sketches of the product experience. I create digital designs of your vision and interactive prototypes so that both you and your users get hands-on experience which we can further evaluate. Once everyone is happy with the designs, I can help with the transition from prototype to development and final product. You are involved in every step of the way and each step can be repeated as often as necessary, until we get it just right.

Need help with your user experience? Want to learn more, or just have a chat? Do you have questions about the process, do you wish for a more hands-off approach, are you looking for UX help at smaller scope, or have a product that could do with a UX overhaul? Feel free to contact me at sven.charleer@gmail.com or @svencharleer .


I have 10 years of UI development experience and spent the last 6 years in academia researching Human-Computer Interaction (what academics call UX more or less). My area of expertise lies in data visualization for both laymen and experts, creating dashboards that improve insights, awareness, and data exploration. I have published articles, given talks, and developed proof of concepts in domains such as Learning Analytics, Digital Humanities, Unemployment Services, and Video Games.

more about me

Happily married, a 5 year old daughter, and living in Brasschaat, Belgium. I have spent 10 years working in the private sector (local and abroad), after which I decided to pursue a PhD with a focus on data visualisation and user experience at the University of Leuven. There I worked on multiple European projects around Learning Analytics and Digital Humanities. Once I became "Dr. Sven", I spent another year in academia as a postdoc working in collaboration with VDAB (the public employment service of Flanders, Belgium) around visualisations for the unemployed. I also researched video game metrics visualisations to improve eSports spectator and team experience. For detailed information on my professional experience, head over to LinkedIn .

These 16 years were great: I've met amazing people and made great friends, worked on a broad range of interesting projects ranging from the HR sector to video games, even designed a dashboard that is now used across the University of Leuven,... but it was time for something new. So I finally made the jump to self-employment, became a free agent, and here I am!

On a more personal level, I am also a blogger and amateur photographer (aren't we all). I'm an avid gamer (currently Battlefield 5 and Super Smash Bros Ultimate), yes I occasionally stream on Twitch, and even share a silly YouTube channel with my friend Frank. I stay healthy(ish) by exercising (yoga, tennis, swimming) and I quit meat over a year ago!


First of all, I wrote quite a few scientific articles. I'll highlight my favorites here. I currently have an h-index of 10.

I take a lot of pictures. Mostly of our daughter. Here are some Instagram highlight.
