Scrum Team

Tatkräftige Unterstützung für Ihr Projekt

HOW WE WORK

Our Methods

Agile

Requirements change constantly, usually faster than you think. We're ready.

Testdriven

Automated tests not only don't lie, they provide security for changes and are a solid base for continuous integration.

Continuous

Things that are painful should be done more often - but not manually. Jenkins takes that off our hands.

CleanCode

Programming languages were invented to find solutions to complex problems. That's what they should be used for.
