Kevin Green, Co-founder and Lead Engineer at The Couch, a web development team, has effectively utilized Gatsby to significantly reduce website development time and costs while enhancing site performance. Focusing on e-commerce projects, The Couch has leveraged Gatsby's ability to integrate with a variety of headless services, enabling them to create fast and feature-rich websites for clients like Prima, a CBD oil company. By serving content as static HTML, Gatsby allows for quicker loading times and lower hosting costs, which are key benefits for content-heavy sites. Kevin's experience with Gatsby, coupled with headless CMSs like Sanity and e-commerce platforms like Shopify, has streamlined his workflow, allowing him to adjust tools to each project's needs and cut development time in half compared to traditional tools. The successful launch of Prima's site, which integrates educational content and a product line, underscores Gatsby's capability to deliver fast, smooth user experiences, making it a preferred choice for Kevin and his clients.
