I worked for a Cisco Premier Partner for 12 years. Most of that time was as a Networking Engineer doing a variety of projects that included configuring and installing routers, firewalls, switches, access points, etc. I now have my own technology services business and do a wider range of work: everything from basic troubleshooting to IT project management of new store locations. Lately, I've been installing and maintaining a handful of Cisco's UC540/UC560 VoIP phone systems. My most applicable certifications include Cisco's CCNP, CCNA, and CCSP. I have a few others as well but don't usually list them. I have experience with a variety of products (routers, firewalls, switches, wireless AP's, voice products. If that kind of thing is important then feel free to ask me and I could give you the full list. I always try to do a thorough job and view my work from the perspective of the client.
