    Starting in 1994, when internet was a horrified 80x25 text character terminal, I had the chance to go through the late 90s internet-boom and the Web 2.0 era. Since then, with over 15 years of experience dealing with large telecommunications companies, Internet Service Providers and data centers, I had the opportunity to work on several cutting-edge IT projects and their associated systems and network implementations. I specialize in Linux and UNIX systems setup and administration at low level (shell) that includes installation, configuration, optimization and monitoring of the operating system and its accompanied application services and protocols such as apache/http, bind/dns, MySQL, sendmail/postfix /smtp, imap/pop3 etc. Also, at the network layer, I've designed and implemented routers based on Linux and/or CISCO platforms offering networking services from simple IPv4/IPv6 routing and its related technologies and protocols (RIP, OSPF, BGP) to more complex network services such as layer 3-7 firewalls, Intrusion Prevention & Detection Systems, VPNs, VoIP & QoS, monitoring, auditing, troubleshooting, security assessments etc. In the recent years of the cloud infrastructure technology, I learnt to deal with XEN and VMware Hypervisors while configuring hardware and software to provide IaaS and SaaS in virtualized environments.  less
