Hi, I'm Oliver Wehrens.

For over 20 years I shaped Technology & Product in companies ranging from startups to major cooperations. I started my career in software engineering and moved to technology leadership in roles like Head of Architecture, CTO and VP Engineering. I transform technology and shape cultural changes in organizations. I am a proponent of the fact that every change in technology, product and organisation triggers a change in the other areas.

Beyond that, I like to share my expertise and learnings at the Mentoring Club as well as in articles here.

Enjoy

Mit Puppet und RPM „It works on my machine“ hat sicher jeder schon einmal gehört. In der Entwicklung verhält sich die Software wie erwartet. Bis diese in der Produktion ist, dauert es lange.

Dieser Artikel reflektiert, wie wir mit diesem Problem auf Basis einer paketorientierten Deployment Pipeline umgehen.
