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

Ukraine - 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.
