DD9 can design and develop mobile-optimized sites and web applications. With the rise of HTML5 and mobile toolkits, these mobile-sites can rival the functionality and performance of native mobile apps.
We can implement mobile web in parallel to the main site on a subdomain, such as m.yourdomain.com. Or, we can design a responsive template which will adapt to the screen area available in mobile browsers.
From scratch design/redesign projects trend toward the later technique, responsive web design. However, this is not always practical, and a parallel system can be the better solution.
