    Hello dear customer, Yes, I'm not wrong, cause after read that you will wanna to hire me ;) Well, now seriously ... I am a highly experienced web developer who has primary direction of activities in e-Commerce web-developing, in that case it's a Magento area. I'am an adept of Magento and if you don't know what is it and you wanna e-commerce site you have to contact with and I will explain how is Magento awesome. I have 3 years experience in Magento and 9 years total in PHP developing with an MVC, different CMS (Wordpress), frameworks (Yii, Zend) and other. I always stick to the coding standards and follow the best practices to provide seamless, readable and reliable code. Besides developing I have some administration skills to manage servers, automate routines and can improve performance of Magento backend and frontend as well. Also I can setup the server from a scratch. I prefer a stack for Magento consists of: Nginx, Php-Fpm, Redis, Apc, Mysql 5.5 (5.6) (Percona better), SOLR/Lucene/Sphinx. I prefer do not install any control panels but if required I would prefer ISP Manager 5 Lite. Magento related Experience and Services - Optimization, load improvements, speed up - Extension development and customization - Troubleshooting - Tweaks & tricks - Bulk importing. Do you have 100k products? It's not a problem - Store migration - AWS, Rackspace building an architecture of you infrastructure - Core upgrade - Magento recurring support - Bug/error fixing - Theme design and customization - Consultation - Code review I also have some basic skills in the desktop programming (C#) and some Photoshop skills. I'll be glad to new acquaintances and long-term cooperation. I have a team of developers and every day we are expanding. Just hard to write all things what I can do. I am easy learnable for new stuff (frameworks, custom systems, foreign code). My strong side is a backend developing and have a good knowledge of a frontend side: - HTML5/CSS3 - Bootstrap - jQuery - Ajax - WebSockets, Long polling - Prototype - ExtJS - Google API, Yandex API - many other things that I can't remember at this moment. Also in a less degree Angular, Backbone and other frameworks/libs. Communication Channel : Skype/Whatsapp/Email/Phone I have listed only a little part of my portfolio cause I have many jobs completed and I can't add every job to profile. ps I hate the Job Success counter feature of Upwork, many clients just forgetting to leave fedback and I can't force them to do it and upwork count that as undone :(
