Timothy J. "Tim" Riker

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.
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!
