I’m Holger Sindbæk. A designer
turned developer from Copenhagen,
Denmark. I develop iOS & web apps
in Rails, React & React Native.

Now I'm working on Slang,
a community marketplace
for young entrepreneurs
to buy & sell authentic
sneakers & streetwear.

I've also made a number of apps, including one of the most popular calculators & one of the most popular online solitaire card games, to get better at React. Lately I've made a habit tracker to help people improve their own life.
