Migrating from Legacy Monoliths to Next.js: A Case Study

Enterprise web portals often struggle with slow initial page loads, monolithic deployment pipelines, and high infrastructure costs.

Our Modernization Blueprint: - Decoupling frontend into **Next.js 15 Server Components** for near-instant Time to First Byte (TTFB). - Building high-speed, type-safe APIs with **Python FastAPI**. - Embedding interactive 3D hero experiences with **Three.js / React Three Fiber**.

The result: a 3.5x boost in Lighthouse performance and seamless content authoring via our custom Admin Portal.
