Wunderman Thompson, a global digital agency, uses Atomic Design principles, a headless CMS, a monorepo workflow with Turborepo, and Vercel's serverless platform to create an efficient developer workflow. They achieve this by choosing the right framework, such as Next.js or SvelteKit, which offers full stack access, component-based architecture, optimized performance, efficient rendering, enhanced developer experience, and adaptive deployment. By applying Atomic Design principles, they create a unified design system that keeps all sites up-to-date and avoids inconsistencies. The use of a headless CMS manages data with a single source of truth, while a monorepo workflow stores code consistency across client websites. Turborepo improves the speed of working with the large monorepo. Vercel's native integrations manage infrastructure, preview deployments, and serverless scaling, enabling seamless development and deployment experiences. This composable workflow delivers impressive results for Wunderman Thompson, improving developer productivity by 10x and slashing costs by 25x compared to a monolithic solution like WordPress.
