Hello. I'm Caspar 👋

About me

I live in Berlin with my family, work as a business analyst for EUROPACE and enjoy coding in my spare time. You can find a list of my projects below.

I sporadically write in a blog about all kinds of things, including some creative writing.

Biggish Projects

Here are 4 things I made that are being used by more than 400 people a day. All them are my own work, bar Kittysplit which is a collaboration.


Kittysplit is a webapp that allows painless cashing up after an event.

Android Wallpapers

I've made a bunch of wallpaper apps for your Android phone. They've been download over 500.000 times. Can you really afford to continue living without them?


A nifty little webapp for keeping track of scores online.


A silly Android app that allows you to send mild spoken insults to your friends and enemies. It's been downloaded over 100.00 times.
