WHO WE ARE
we are cronn
We are cronn - a Bonn-based software development company with branches in Hamburg and Białystok, Poland. Software development is our passion. We trust in Java, OpenSource and, last but not least, in our experienced team. All of this we deploy to bring our clients software that is key to their business, or to professionally consult them in issues regarding architecture, tools or approaches.
HOW WE WORK
Requirements change constantly, usually faster than you think. We're ready.
Automated tests not only don't lie, they provide security for changes and are a solid base for continuous integration.
Things that are painful should be done more often - but not manually. Jenkins takes that off our hands.
Programming languages were invented to find solutions to complex problems. That's what they should be used for.
