Hello,
I am a Linux sysadmin with strong knowledge in asterisk and Nagios monitoring. I setup a broad range of Nagios servers, the biggest with over than 90 host and 1200 services, checking every kind of the systems. I am also a C, bash script and php developer, and usually I develop my own probes when the available ones are not satisfying me. Usually I add a graph to each probe for easy trend discovery. No problem on setting up OpenVPN server, in certificate or shared key mode, tcp or udp, routed or bridged mode. About me, I am italian, GMT+1, ready to work for you.
