    I am looking for projects that I can complete on a part-time basis. They can be either short term projects or long term projects. I can also provide ongoing consulting and administration if needed. I bring to the table a broad base of networking infrastructure design and operations skills ranging from data center implementation to mobile workforce networking. I have worked on projects for Fortune 500 companies, U.S. Federal Government, and private industry. My current focus for my oDesk clients has been Cisco ASA, SonicWALL NSA and SRA implementations, Meraki (Cisco Cloud) and support. If you have a project that fits the bill, I would truly appreciate your consideration.  less
