I'm able to: – create from scratch web-application using various technologies, – move complicated web-site from one technology to another (or from one CMS version to another), – improve or extend existing web-solution according to customer business needs. To do this I can: *** develop custom modules and themes for Drupal 6/7/8 and use standard modules (Views, CCK, Panels, Rules, Token, Internationalization, Wysiwyg, Webform, etc); *** write scripts for other CMS frameworks (Zend, WordPress, Modx Evolution, Joomla, Openmart); *** implement solutions on the server side (PHP) and the client side (JavaScript/JQuery/Ajax/AngularJS); *** perfectly create HTML5/CSS3 (also SASS) from PSD with cross browser compatibility, W3C valid; *** do responsive, mobile friendly websites using @media queries; *** create simple and complex SQL queries; *** use version control systems (SVN, GIT including GitHub).
