Linux/Solaris servers administration and configuration. Our team was responsible for voice/video messaging systems based on VoIP technology (voice box) and our customers were fixed and mobile operators all across the Europe like Vodafone, France Telecom, Belgacom or H3G. We used especially SS7, H.323, SIP, RTP and RTCP protocols, but the solution was also based on VoiceXML, LDAP, IMAP and SMTP. I also got experiences with configuring VoIP gateways, switches and load balancers and improved my knowledge about Sun Directory Server 5.x (LDAP), Sun Messaging Server (IMAP), Apache web server, Veritas Volume manager and Veritas cluster. The high availability solutions based on HA Clusters, loadbalancers and disk arrays provide 99.9% availability of the service to the customers. Specialties: Good understanding of programming language Perl, BASH, LaTeX, VoIP and packet switched networks. I have experiences with configuring Radvision/Cisco gateways, switches, disk arrays and managing LDAP, ftp, email and SQL servers. I also have experiences with HA environment, clustering and storage solutions. I have good knowledge of Linux and Solaris servers administration.
