An early iPhone app for sending real-world postcards

Kartensender is a smartphone-to-mailbox postcard sending service. During the launch and first few years of operation I worked as its “CTO-for-hire”, writing all server side code and managing technical contractors.

Starting from a German iPhone app, Kartensender grew to include Android, webOS, Windows Phone and web apps in several languages. Add to that tens of white labels and bags of cards sent every day.
