I'm Johannes, a full-stack developer from Hamburg with a passion for turning ideas into useful apps and services. Over the last few years I've helped startups and small businesses launch digital products that solve real problems.
My recent projects include Heizkostenvergleich24, a website for calculating heating costs and heat load, and Hundekunde Pro, an iOS and Android study app for dog owners preparing for the mandatory exam.
When I'm not coding you'll find me out kitesurfing, riding my road bike or playing beach volleyball.
