Solid understanding of communication and web technologies is my primary area of interest and expertise. 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've setup BGP so the provider can have a backup route for his services. I'm falimiar with the nature of the technical issues that can occur and the different ways of handling and preventing them. 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.
