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. I've been working with Debian GNU/Linux professionally for 2 years as a systems administrator for a Bulgarian tourist resort and 2 years maintenance the services infrastructure (web, mail, vpn, samba, domain management, monitoring, ticket resolution systems, asterisk voip). I worked at a web development company for a year, doing back-end web development with different and frameworks, such as django, rails, express.js, along with infrastructure administration tasks and support.
