In today's fast-paced ecommerce landscape, customers expect websites that cater to their shopping needs and provide seamless digital experiences. To stay competitive, brands need nimble tools that enable agile development, experimentation, and adaptation to market forces. Many legacy monolithic systems hinder this, but API-first tools and composable architecture offer a solution, allowing teams to work in parallel and turn out features quickly. A progressive re-platforming approach can help decouple the UX layer from the legacy system, reducing risks and enhancing user experience. Brands that adopt agile practices and use the right tools can thrive despite uncertain times.
