My name is Frank Reimer. I am an IT specialist and freelanced IT consultant based in Schleswig-Holstein close to Hamburg, Germany. I have more than 20 years of professional IT experience focused on IT Infrastructure Architecture and Systems Engineering.

Mostly I’m working with Linux (Red Hat certified) and Opensource tools used in modern IT datacenter.

Beside conservative environments with traditional IT silos with dedicated teams for network, storage, compute, operating system support etc. I have established and worked with cross functional global working teams to build new agile IT platforms ( e.g. with Openstack, Docker, Kubernetes, Openshift) to support DevOps teams with their fast development cycles.

I am familiar with building an on premise Coporate Private Cloud with IaaS and PaaS components including Software Defined Storage and Software Defined Network. Always with focus on Software Defined Datacenter.

I have also experiences in DevOps engineering with CI/CD pipelines running on Jenkins and Git as well as Python scripting and automation with Ansible and Terraform or traditional configuration management with Puppet.
