I have worked with Andreas for over a year on various JavaScript based applications. He is everything you want in a developer. He is consistent, asks the right questions, is clever, and always seems to get the job done right. He has assisted me in many customer projects requiring HTML5 / Javascript dashboards and transactional apps. I highly recommend Andreas

Of the 20 something web developers & digital marketers I have used for various tasks in the past year, Andreas is the first person I talk to when I have an idea. He takes ideas and makes them better than you were originally thinking and he never asks you to review something that isn’t finished.

The quality of his code and creativity is worlds class. It’s a joy to work with someone where things get done to such high quality without the need for lots of revisions. He has a bright future ahead of him, but for as long as he is available, he is my go to dev.
