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.
