About me

Hi, I’m Kasper. A Creative Developer with a focus on Digital Product Design based in The Netherlands. I create new user experiences by tinkering with different technologies and tools. I run an academic minor course named Creative Design & Technology and teach about Digital Product Design.

I can help you building digital web applications, MVPs, and interactive installations. I believe that experience comes first. Technology should always facilitate the user experience. I love problem-solving, and I’m happy to think along. Feel free to contact me.

I can help you:

  • building digital products and progressive web apps based on an amplitude of technologies. Tools in my toolbelt: Particle Photon (Internet of Things), Arduino, Processing, HTML/CSS, PHP, Javascript, Vue.js and Svelte. 
  • decide which technologies and products serve the best for your application and budget.
  • do customer research and user experience design (interaction and design for emotion).
  • to make products hear, see, feel, glow, move, show, sound, communicate, and …
  • to create courses and teach about Digital Product Design and Development. 

You can read more about me at my LinkedIn page.

Below you see a selection of web work I’ve done in the recent past.


Zwemindex is a directory with official swimming spots (lakes, sea, other water) in The Netherlands. You can find the swim spots (in nature and pools) close by the city you live. The site uses public data by the Dutch government. The goal was to help people find spots to swim nearby in an easy way. My technical goal with this project was to make a “programmatic SEO” search directory. People can do searches in Google like: strand dichtbij Breda or recreatieplas in Utrecht and they (hopefully) end up on zwemindex.

The site also display warnings for blauwalg and other unsafe situation on the special blauwalg radar page.

Please contact me if you if you like to build a programmatic SEO directory like this (in The Netherlands or somewhere else).
