Your website is the one channel you actually own. We treat it that way: a proper discovery phase, a sitemap and wireframes before a single pixel is designed, then UI and UX work you approve for both desktop and mobile.
Development covers the front end and either a back end or a CMS, depending on who needs to update what. Before launch we load the content, do the basic speed and SEO work, run internal QA, then test it with you. Go-live comes with a handover and written documentation.
