Attn: Human Resources Department

To whom it may concern;

I am seeking a career as a Senior Unix Systems Administrator.

I am a driven UNIX administrator with a solid base of experience ranging from the dot-com enterprise to public-sector trusted infrastructures. My core competency is focused in the information security field.

I bring with me a broad range of career experience. My skill-sets vary from retail and corporate sales, to sound engineering and tour management in the music industry.

Excellent communications skills are not only a requirement for these fields but come as second nature to me.

I have been deployed in the public sector for the last several years and I am looking for a change. I am ideally seeking a dynamic, casual workplace, a growing enterprise and an environment that takes their IT vision seriously.

My goal is to continually further my expertise in my field, with pursuit of industry certifications as well as continuing education in this dynamic specialty.

I am confident that with the proper position I can offer your organization a tremendous yield in both leadership and technical expertise. If you should have a position that may suit our goals please contact me at your earliest convenience.

Thank you for your time;

Chris Esser
