As an IT Architect and Senior System Administrator my main areas of work are business-critical Unix systems (HP-UX, Linux, Solaris), high-availability solutions and storage systems (EMC, HP, NetApp) as the basis of critical IT infrastructures – locally („on- site“) or in the cloud.

My services encompass consulting, conceptual design, planning and implementation of solutions, operation and organisation of the operating structure, optimizing, support and troubleshooting including delivery of training, coaching, and documentation.

I don’t sell any products and therefore I am not bound to any particular manufacturer. Hence my customers can be sure that I shall always work towards the optimum solutions for any kind of problems and will always act in their best interests vis-à-vis their customers and suppliers.
