Over the last 7 years I've been a tech support for an ISP, a systems & network administrator and a web developer. As a network administrator for 2 years, I discovered what it means to maintain a large-scale MAN (Metropolitan Area Network), including internet access, setting up and managing IPTV streaming through IGMP and IGMP snooping techniques.

I'm experienced in ethernet & GePON networking equipment. I've managed network equipment from most major vendors, Cisco, HP, DLink, Dell and Fundry, just to name a few.
