Senior UNIX (HPUX, AIX and Linux) Systems Administrator

Objective

Seeking a senior level opportunity with a small, medium or large scale enterprise IT operations department, as a UNIX systems administrator, engineer and architect. I would like to transfer my 22 years of UNIX experience combined with 10+ years of mission critical data center operations background, into a new challenging environment. I would very much like to apply my experience in a supervisory role, mentoring the inexperienced. I'm open to relocation within or outside the United States, for the right opportunity.
