    Nikitas Skemvris

    Systems Administrator and IT Engineer

    United Kingdom - Tests: 6

    I am an experienced Systems Administrator, having worked for many years with a broad range of fairly complicated technologies, products and tasks. I like to understand how an implemented system works and dislike relying on trial-and-error or luck. I am eager to analyze the costs and benefits of alternative solutions, examine the requirements of each situation and make informed suggestions on how they could better be served. I draw real satisfaction from automating routine tasks that would otherwise require human labor. I prefer to work with Unix-like systems, but I have long experience in administering and supporting Windows Servers as well. Key Skills: • Hardware: Assembling computers, identifying and replacing faulty parts • Common Office software: Word/Excel/Access/Powerpoint • Systems Administration: GNU/Linux (Slackware, Gentoo, RedHat/CentOS, ArchLinux, Debian), FreeBSD and Windows Operating Systems • Designing and Implementing secure IP Networks based on Ethernet and WiFi • Installing and customizing numerous Network Service software, including: Postfix, Dovecot, Apache, Nginx, Varnish, MySQL, PostgreSQL, BIND, PowerDNS, NFS, Samba, OpenSSH, NTPd, Squid, Rsyslog • Relational Databases: SQL • Firewalls and Traffic Control: Iptables, Iproute2, PF • Virtualization: Vmware ESXI, Microsoft HyperV, Linux Vserver, OpenVZ, FreeBSD Jails • Languages: Python, Ruby, PHP, PERL and BASH (Note: I don't consider myself a Software Developer, but I am able to develop small applications that automate routine tasks or import/export/analyse/present data in helpful ways, following proper programming practices)

    Unified Communications Professional / VoIP Expert

    Australia - Tests: 5 - Portfolio: 3

    I have been working with VoIP for more than 9 years. My area of expertise is Cisco Unified Callmanager, CUCME and other Cisco Unified products, such as Cisco Unity, CUPS, CUE, ISR routers, 26xx, 28xx, 29xx, 7xx series routers as well as non-cisco solutions based on Asterisk, Mera (ALOE). As a certified CCNP Voice specialist I suppose I can solve any complex issue relating VoIP networks. Not only do I have a real experience of working with cisco products, but I am also able to perform various systems administration tasks in FreeBSD/Linux systems. So if you desperately need a professional for providing proper functioning of your Unix servers, you may ask me to do that. Also, I would like to mention about my experience of working with vmware products. I have installed several vmware ESXi platforms for cisco unified and other solutions, and all these platforms work perfectly.
