    Dear potential client! I am a Russian-based web developer, my professional objective is to find an interesting job in the field of Web development. I enjoy working on serious projects (high-performance, based on the newest technologies) and working with the technology that is usually referred to as "Web 2.0", and more recently, "Web 3.0." My primary focus is architecture and backend development (PHP: Symfony Zend), DBA (noSQL - MongoDB, Cassandra), but I also have strong knowledge of JavaScript programming (Node.js, Backbone, Coffeescript, Socket.IO) with XHTML and CSS. My specialization is PHP development, for which I prefer to use SF Doctrine ORM, as well as Node.js with Sequelize Doctrine ORM. I use MySQL 5.x, working with implementation of logic by stored procedures and triggers, and of course for high-performance projects I use noSQL (MongoDB or Cassandra), but I always select the tool appropriate to a particular application in order to achieve maximum performance. For instance, I will never use Node.js simply because it is modern, but instead only when an application is well-suited to Node.js because it requires persistent connection from the browser back to the server. I always make sure my code is fully functional, and also well-structured and easily maintained. To achieve a more efficient and higher quality project structure as quickly as possible, I prefer to use such frameworks as SF 1 and 2. Please feel free to contact me to discuss the details of your project, or if you are interested in my services. I'd like also like to mention that if you have a complex development project, we can also assign additional programmers to the task. I look forward to working with you.  less

    Dear potential client! I am a Russian-based (Taganrog, GMT+4) Web developer: My specialization is PHP development, for which I prefer to use Symfony 2 (Symfony 1) with Doctrine ORM, as well as Node.js with Sequelize Doctrine ORM. I use MySQL 5.x, working with implementation of logic by stored procedures and triggers, and of course for high-performance projects I use noSQL jQuery: I love to work with jQuery and plugins. I first worked with jQuery 1.2 in 2008, and have working with all subsequent versions, including the current jQuery 1.8. I like to add AJAX to my applications, but I always take care of SEO aspects meanwhile. For example, if I implement an AJAX search on your site with dynamic listing, it will also work if javascript is disabled (AJAX would also be disabled) in your browser, so search spiders will still be able to parse your page with an AJAX search.  less
