Northwind Logistics came to us with a customer portal that had grown organically for eight years. Every page took four seconds to load, the codebase resisted change, and their support team fielded a steady stream of tickets from frustrated users.
We began with a two-week discovery: mapping the critical user journeys, instrumenting the existing app, and identifying the handful of pages that drove most of the pain. Rather than a risky big-bang rewrite, we adopted a strangler-fig approach — routing new, rebuilt pages through Next.js while the legacy app kept serving everything else.
The new architecture leaned on server components, edge caching, and a shared design system. Within twelve weeks the core portal was fully migrated. Page loads dropped from four seconds to under one, and support tickets related to the portal fell by a third.
The lesson: you rarely need to rewrite everything at once. A disciplined, incremental migration lets you ship value early and de-risk the whole project.
