Oleg K.

Senior Back-End Dev: Perl/Catalyst/DBIC+AJAX/jQuery, shell+sysadm

Ukraine - Tests: 16

Seeking opportunities in Perl oriented (Catalyst DBIC preferred) application development, shell and perl scripting, and BSD/Linux administration projects - to build sites and setup servers for your business or pleasure.In my mind, LAMP more often reads as LASP - Linux, Apache, (any|no)SQL, Perl - of course, with Catalyst, Template Toolkit and DBIx::Class/KiokuDB in pair with some RCS (git is preferred, but subversion, mercurial and others also possible). And of course, all can be integrated with AJAX libraries such as jQuery, Prototype, MooTools and other to create Web2.0 apptications.Great knowledge of regular expressions (regexp). Have real experience with MySql, Postgres, Oracle, CouchDB, LDAP, also worked with CPanel, Plesk and Ensim. And of course, have experience with Apache, SMTP (exim, postfix, sendmail), IMAP/POP (Cyrus, UW, Dovecot), firewalls (bsd/ipfw and linux/iptables), Samba and misc ftp and proxy solutions.I can work well as alone and as a team member.

Linux SysAdmin, Python/Django

United Kingdom - Tests: 4 - Portfolio: 3

I have been working as Linux System Administrator for 5 years. I supply linux management service for my customers. I design and install infrastructures for high-available web applications. Most of these servers use Debian, Ubuntu, CentOS, Redhat and Pardus. I use haproxy as load balancer, iptables as firewall, apache, nginx or lighttpd as web server, mysql as database server. I configure replication systems which have one or more slaves. I deploy applications in different languages like RoR, Python/Django or PHP. I am familiar with php-fpm, php-cgi and mod_php. I am also experienced in virtualization. I use openvz, vserver and kvm for virtualization. I prefer using Debian or Proxmox for host system for virtualization. I use Python and PHP to develop web and shell applications and automation scripts. I am a free software contributor. So i am good at remote working and collaboration tools. I use git and svn actively for various projects.
