Technology stack
A stack says little about quality. It says something about what we have already operated — and that is the more relevant information.

Putting it in context
This list is not a recommendation. Which technology is right depends on the problem and on your existing system landscape — which is why technology evaluation on a solid decision basis is part of our architecture work rather than of the sales conversation.
The in-depth view by field of application is under Services.
