Attn: Human Resources Department
To whom it may concern;
I am seeking a career as a Senior Technologist or Pre-sales Engineer. I am open to positions not specifically related as long as technology plays a heavy role.
I'm a self driven technologist, If I had to pick a title, it would be "Technology Fixer". I bring to the table a broad base of experience, centered in the Unix enterprise and it's operations. I am a solutions Swiss army knife.
My core strength centers on analysis of work-flows, process and architectures. I enjoy looking into business technology issues and deriving the best practices solutions to enhance efficiency and stability.
In addition to systems architecture, I bring with me a broad base of career experience. My skill-sets cover retail and corporate sales, sound engineering and tour management in the music industry, as well as a background in RF communications.
Excellent communications skills are not only a requirement for these fields but come as second nature to me. I am an outgoing and social personality and I enjoy client interactions in the business process. Bridging the chasm between "The Business" and the technology groups is my daily mission.
I am seeking a dynamic environment with varying challenges. I like an active and casual environment that moves at a fast pace. One of the things I have missed in the last few years is the variety found in field situations. Variety of people and sites is a must.
I would prefer a position that is not anchored to the depths of the cubicle farm of typical technology departments. Ideally I am seeking a sales or pre-sales support role with a local/regional territory.
I am confident that with the proper position I can offer your organization a tremendous yield in both leadership and technical expertise.
Thank you for your time;
Chris Esser
