    Senior Dev: Perl/Catalyst/Moose/DBIC/NoSQL+AJAX/jQuery, shell+sysadmin

    Ukraine - Last active: 1 day ago - Tests: 19

    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.

Where conversely some of my most recent and earlier career experience was based in one of the most competitive customer service industries, and to achieve success in this, I had to be flexible to market conditions, so that I could maintain strategic focus so as to continually meet my financial targets. The combination of my career experience has provided me with the opportunities of working in USA, Belgium, France, Spain, Gibraltar, Abu Dhabi and secondments to Brazil, Mexico and APAC, for projects that I was either managing or transferring to local piers and latterly I had responsibilities for USA, Germany, Italy, Switzerland and Denmark.
