Objective
|
I would like to work with servers (Linux preferred) and
optionally networking equipment. I not only can, but enjoy
working on several projects at once. I have worked independently
and with a team, and enjoy learning as I go. I currently work as
a consultant, primarily from home (ssh), but am open to the right
full-time position.
