Career Objective:

Seeking senior position in new technology development, combining project leadership, programming, system design and administration with innovative abilities. Should include a flexible environment with creative latitude and appreciation of individual attainment. Particular interests include Linux, OpenSource, Android, embedded systems, clustering, Storage Area Networks, full text search engines, networking, and data compression.

Special Note:

If you are a recruiter reading this, please don't send me an email asking me if I'm interested in a web server administration position. I'm probably not interested in anything under $130k/yr. For other areas of the country please convert from Salt Lake City, Utah to local cost of living. Also, please don't email me asking for a copy of my resume in Microsoft Word format. This tells me two things: you are unable to cut and paste this version of the document and therefore unlikely to be a skilled recruiter; the position you are trying to fill is likely constrained by the restrictions of a Microsoft only environment. In either case I am probably not interested in talking with you further. No offense intended, just the realities of the business world. Thanx!
