ostec values - fast, secure and agile

Performance

We love performance on a snowboard, in a car or on a run. No difference for servers, sites and apps.

Security

It is not just about caring for security during development but about constant improvement and monitoring.

Agility

At ostec this is not just a buzzword. It really gets projects done faster and saves money.

Quality

Contiuous and automated unit tests, behaviour tests, integration tests, regression tests ... you get the idea.
