    XHTML/CSS/Flash/Photoshop/Illustrator Pro in Seattle, USA

    United States - Last active: 8 hours ago - Tests: 17 - Portfolio: 3

    Over the last several years I have developed many websites using a variety of methods. I enjoy the flexibility that CSS/XHTML provides, so that is my medium of choice - all of my work is standards-compliant (XHTML 1.0 strict), and I have also converted many outdated sites into standards-compliant sites with table-free CSS layouts and improved functionality, leading to a better overall user experience. In addition to web coding, I have extensive experience in photography and traditional graphic design. My goal is always to produce sites that are as visually appealing as they are functional. I also have experience working with ColdFusion, Flash, PHP, JavaSript, and related technologies, and can convert PSD files into themes for Wordpress, Joomla, osCommerce, and similar formats, with great attention to detail and retention of full functionality. I believe in keeping 'the big picture' in mind - I incorporate SEO techniques into every project, and plan projects to allow for future expansion and updates.

    Back-end and front-end dev and photographer

    Ukraine - Last active: 1 day ago - Tests: 2 - Portfolio: 1

    I specialize on Ruby on Rails and front-end development. In spite of the fact I have got a degree in International Journalism and Translation, I worked as QA and IT Sales for total of 3 years (from 2008) and then moved to web development from Jan, 2012. I have performed both back-end tasks (from basic CRUD to making simple APIs or server scripts) and front-end (building static websites from scratch or developing views with twitter-bootstrap). I believe the experience is formed with the quality of the projects, you have delivered, and not with the years of sitting in front of the laptop. Specialties: ruby 1.9.2+, Ruby on Rails 3.0+, linux and MacOS X environment, unix-shell, Git, SQL (SQLite, MySQL, PostrgeSQL), HTML, Haml, CSS, Sass, Less, twitter-bootstrap, javascript, jQuery Here is link to my github profile: https://github.com/amseledka I do photographs and various design tasks in my spare time, as well as help my friends with Russian-Ukrainian-English translations.
