How do we develop software?

Each team works on its own part of the software. These can be customer-oriented components, but also our warehouse system or our own HR system. You develop, optimise and implement new features. We develop all the systems we work on ourselves, so that we can respond effectively to complex and challenging changes in the market. We also use the systems ourselves, but we build them as independently functioning software that is also interesting for other companies. So, although we are also a web shop, we see ourselves as a software company. So our scope is much broader than you might think.
