    Miranda R.

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

    United States - Tests: 18 - 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that is my medium of choice - all of my work is standards-compliant (XHTML 1.0 strict), and I have also converted many outdated sites into standards-compliant sites with table-free CSS layouts and improved functionality, leading to a better overall user experience.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.
