Built a wifi Metropolitan Network across Macedonia, Greece. This is a private network made by hobbyists. The network connects major cities of Macedonia (Thessaloniki, Katerini, Veroia, Giannitsa) using wifi technology. The backhaul links use the most modern technology of IEEE 802.11 standards like n/ac. We use various routing protocols for the routing of the network (Static, BGP, OSPF).

Chair

Nov 2013 - Oct 2016
As the Executive Officer of the Branch, the Chair is the key to effective student leadership. Our branch has 30 active members. Every of our event attracts more than 50 students.As Chair, I am responsible for the overall management of all Branch affairs. However, in order to be effective, I am skillful at the art of delegating. I've delegated some of the responsibilities to the other members of the executive committee. Also my main goal as a chair of the branch and member of IEEE is to motivate people to do more than the undergraduate program offers, attend workshops seminars and hackathons. Show less

During the World University Debating Contest 2016, which was held in Thessaloniki, there was a need to provide internet access to 1500 participants and organizing committee. My responsibility was to configure and install 18 routers across the campus of American Farming School of Thessaloniki. Also due to strict policies of the campus the participants must be able to connect only to one website for the contest. In order to accomplish that I've configured a web proxy with policies and routed all the traffic through that. Show less
