    Alexander Avanesov Agency Contractor

    HTML/CSS/JS ninja, iPhone/iPad developer, Magento/PHP expert

    Russia - Tests: 15 - Portfolio: 12

    Alexander is a lead developer of our front-end team. He has deep and strong knowledges of HTML/CSS and large experience in these areas. He worked on many projects. Some of them use top technologies such HTML5 and CSS3, the others perfectly work in outdated browsers like IE 6/7. Alexander is our JavaScript jedi. He writes many nice applications that work in all browsers. Sometimes, we think that he has an in-built JavaScript interpreter in his mind because his solutions and advices are always correct and reliable. He can be working on a task for a long time but when he runs his code in a browser, you won't see any errors. All features will be working correctly. None of us can understand how is he doing it :) Alexander is good not only in the front-end development. He has been working with .NET and PHP platforms long time. Alex knows the most famous CMS (Wordpress, Joomla and Drupal) and shopping carts (Magento) very well. He also wrote a couple of native applications using Windows Mobile using .NET Compact framework. The latest thing he started to learn is the programming for iPhone/iPad. We know that he wants to port the mobile applications he wrote in the past to iOS just for fun. We know, he will be an expert in iOS soon. So, if you really need a front-end rockstar why don't you try to hire Alexander and let him does his best?
