Objective:
To use my skills, experience and adaptability to obtain a position as a Senior
Network/Systems Administrator that lets me utilize my extensive administration
experience and team management skills. My greatest strength is my ability to walk into a
new environment and be functional immediately. I am quick to learn and adapt to new
situations, configurations and technologies.
Summary
Unix systems and network administration are my primary interests. I have extensive
experience with multiple UNIX-based operating systems with an emphasis on Linux but
also FreeBSD and Solaris, Cisco/Dell networking hardware, system and network
security, network design and unix backups. I have experience with high traffic
networking including load balancing technology. I use Perl/Shell scripting on a regular
basis for system administration tasks and am familiar with some C/C++ programming. I
learn new concepts and systems quickly and am receptive to new ideas. I work well alone
or in a group and also have experience managing groups.
