I am working as a freelance digital art director & user interface designer. I was born in Hamburg, but i am working wolrdwide on digital tools & products. 
This are my selected cases.

Tools & workflow

Sketch is my prefered tool for
user interfaces, responsive designs & simple wireframes.

Of course, Photoshop is still an important tool for creating looks, moods & composings. 

I use After Effects to animate transitions, ui behavior & journeys for clients & developer.

Currently i am learning Framer.js for testing differnt user experiences in simples prototypes.

InVision, Basecamp & Slack are my favorite tools for a smooth working process.
