Software Architect. Photographer. Musician. Dad.
By day I work as a Senior Lead Software Architect at an IT consultancy in Germany. The apps here are my free-time projects — small, focused apps for iPhone, iPad, and Mac. I also speak about mobile development and security at conferences and meetups.

karacho.peterkurzok.deI speak at iOS conferences about the security side of app development: what your app stores, how it talks to your backend, and how to tell a real device from a fake one. If you run a conference or meetup and want a talk like that, get in touch.
