Sandcastle Web Design and Development

Based in Burien, Washington, this small team has been operating since 2001, working with businesses that need web platforms and e-commerce systems built or maintained over the long term. The company size stays small, between one and ten people, which points to a boutique operation handling projects directly rather than through large account teams. Its service list spans web design, e-commerce, mobile solutions, and ongoing digital marketing support, suggesting clients ranging from companies launching new online stores to those needing continued technical upkeep. The service range covers web design and development alongside e-commerce builds on platforms such as Shopify, nopCommerce, AbleCommerce, and BigCommerce, plus e-commerce migrations and replatforming for businesses moving between systems. Custom application development is offered alongside more specialized integration work, including cXML PunchOut integrations and AI application development, along with Shopify app development for merchants needing tailored store functionality. Content management systems and mobile app development for iOS and Android round out the build side. On the ongoing-support side, the agency lists hosting and maintenance services, including WordPress care plans aimed at keeping existing sites running. Marketing-related work includes strategy and consulting, search engine optimization, and pay-per-click advertising, positioning the agency to support clients not just at the build stage but through subsequent visibility and traffic efforts as well.
