    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)
