JOOMLA, Laravel, php, Wordpress, MySql, Ajax, JQuery - more then 10 years experience. I'm working as Joomla developer since 2008. Throughout this long journey I became expert in developing all Joomla extension types that are efficient, complying with Joomla MVC standards, exactly meeting client and business requirements. My experience enables me to help customers to find the best solution for their problems, also I'm helping them to enhance/modify their requirements and the solution based on existing Joomla features they don't know about yet. Due to the large number of Joomla extensions I have developed, I know exactly how to customize any Joomla extension such that it keeps being update-able ,as much as possible, in case the original developer releases any update in the future, for example I customized joomshopping, Virtuemart, Jomsocial, etc.. Working as a freelancer, I learnt how to guarantee customer satisfaction to build long-term relationships, starting from discussing the project details to meet all the client needs, up-to providing a perfect price along with high quality and prompt support. If you want to achieve your goals and complete your Joomla projects exactly like you wish, you can depend on me.
