Johannes Waltsgott
Mobile Developer
I’m a professional Android developer, quick learner and team player. My greatest strength is a keen perception of requirements. I've a Diploma in Media and Computer Science and worked for different companies (entertainment, logistics) with international teams as Android developer and Project Manager. To get my head clear, I run with my dog, attend rock shows and go sailing.
