    PHP Expert

    I hope I can help you to solve your PHP website issue. My technical background includes: - 5+ years of PHP development experience: CMS, CMF, Frameworks (mostly Symfony and Zend), Maintenance Scripts, Data Mining, Image Processing and so on. - Decent MySQL knowledge - Optimization, Stored Procedures, Basic Tuning. - JavaScript - most of my professional years I used jQuery, in custom CMS, Symfony and Drupal. Besides that I have noticeable experience in a pure JS writing. - Drupal. Working with it for about 4 active years, my drupal.org profile is https://www.drupal.org/u/angerslave - Web page rendering optimization - I think it's a very important aspect of a website and it hasn't enough attention that it deserves, so I've extracted this skill as a separate knowledge. In my work I try to understand client needs and satisfy them, not just "do the tasks".
