Build great, digital products efficiently

The beauty of digital product development is: “Anything is possible, it’s just a matter of time and money.” That’s also it’s curse. Because it enables both the decision for a completely insufficiently small solution for a product idea and a overwhelmingly complex solution.
A too simple solution will not even support minimal scaling for the underlying business idea. In the same way, one can - with sufficient resources - spend an enormous amount of time (and money) on the selection, architecture and development of a solution. The resulting product is often over-engineered and over-complex and therefore hardly effieciently maintainable.
Therefore, with every product development, I always try to understand the underlying business first and find a solution that fits the business case efficiently, e.g. by selecting suitable third-party tools and rather buying than building things.
Always keeping in mind that knowledge has to stay within the team to be able to support the business going forward.

Open Source

Unfortunately, it is still far too seldom that I myself have contributed my share to the open source community. Here are a few projects that I have developed or contributed to.
