    Russia - Last active: 04/18/2013 - Tests: 22 - Portfolio: 2

    I've always thought, that business goals of a company should be the main reason behind everything else. While being an experienced developer myself, I saw many projects fail, because of the wrong priorities, but as a technical expert I couldn't do anything about wrong business decisions made during the planning phase, no matter how skillful I was in my duties. To prevent possible failures, I started contributing my skill and expertise during the earlier phases of development. Soon, I was the one, who actually proposed the ways to compete against rivals and assured, that they were realized correctly. So now, my prime job is business consulting and project management, but I'm still participating in interesting projects to be in touch with all new technologies over there.

    Systems Administrator and IT Engineer

    United Kingdom - Last active: 01/17/2014 - 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)
