    Web application development

    Poland - Last active: 03/14/2011 - Tests: 14 - Portfolio: 13

    In my over 10 years of web development adventure I developed many sites (some of my latest work is in my portfolio) and I grew addicted to coding. About 6 years ago, bored by PHP, I stumbled onto Ruby on Rails which quickly became my favorite tool. I developed 3 large applications by myself and coauthored at least 2 more.I enjoy writing JavaScript code for some time now specializing in jQuery library.For over 4 years I was working as Expert Webdeveloper for largest online auction platform in Central and Eastern Europe, where I share my jQuery expertise among fellow webdevelopers. Later I got promoted to CTO of project (daily deals app). In late 2013 I got another promotion, to IT Manager. I am interested in everything from server administration, Ruby on Rails, node.js backend coding, HTML5, CSS3, JS frontend development to IT leadership focusing on employee engagement.
