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.

I am an expert in installation, tuning and optimization of the servers and PHP applications such as Wordpress, Magento, Opencart, Atlassian JIRA, etc. I’m usng NginX and Apache servers. I'm a fan of NginX and expertise in this server. My No. 1 goal is to meet my client’s needs, to do the task in time and of high quality. When I work on a new project, I like to communicate with a client, in such a way I can have a clear understanding of his/her vision of the project. The most frequent issue which I face is tuning of Linux servers optimization on which Wordpress, Magento or OpenCart are hosted. My goal is to achieve maximum productivity of the server and to adjust it so that the content will be delivered with high performance and to make the server handle high load of traffic. I use Memcached, Varnish, w3total cache plugin for WP to improve performance and optimize server. I’ve accomplished some projects the results of which are impressive: the load of one project was 5000 online unique users, and the total of requests in another project was 50000 for 5 minutes. After server optimization I perform load testing using apache benchmark and siege. These utilities give the chance to estimate traffic which the server will be able to handle. I use Amazon Web Services, DigitalOcean or Linode cloud providers and recommend them to my clients. Their servers are rather reliable and fast. I use Postfix or Exim in the bundle with Dovectot as an e-mail server. For Inbox control it is necessary to adjust DKIM and SPF for email. For secure connection - SSL certificates adjustment is essential. Technology Expertise: Operating Systems: Ubuntu, Debian, CentOS, Gentoo, CloudLinux, OpenBSD, NetBSD and FreeBSD Cloud Hosting: DigitalOcean, Linode, SoftLayer Web servers: NginX, Apache Database Servers: Mysql, Percona, MariaDB Mail Servers: Postfix, Exim, Dovecot Stack installation and optimization: Wordpress, Magento, Opencart, PHP and accelerated by Memcached and Varnish Skills in programming and scripting: - Bash Service description: - Linux server administration, problem-solving, performance and upgrades - Amazon Web Services (EC2, Route 53, Cloudfront, RDS, S3, SES) - Server Management for CentOS/Debian/FreeBSD servers on Web-projects based on PHPEmail Server - Nginx install, upgrades, troubleshooting and performance optimization - Apache install, upgrades, troubleshooting and performance optimization - PHP install, upgrades, performance troubleshooting and performance optimization - MySQL install, upgrades, performance troubleshooting and performance optimization - Website migration - LAMP / LEMP speed optimization - Magento speed optimization - Wordpress speed optimization - Joomla speed optimization - Drupal speed optimization - Varnish setup and tuning - Maintenance, configuration, white-listing, spf, dkim, high load delivery etc. - Google page speed, site speed and web server performance tuneup
