I'm a software developer, working as an independent contractor from Hamburg, Germany.
I'm a PHP professional and actively participate in the Open Source scene.
I'm specialized in backend programming including media handling, internationalization, API design, payment processing, thorough testing and anything else that leads to high quality code.
