How NuFlights Built a Scalable Multilingual React Platform for 51 Countries

Travel is inherently global. A travel agency in Casablanca handles the same booking workflows as one in Singapore — but their agents speak different languages, operate under different business conventions, and expect software that feels native to their context. When a platform serves a single market, internationalisation is a nice-to-have. When it serves 51 countries, it is a baseline requirement.

This article describes how we approached the challenge of building a production-grade internationalisation architecture for our multi-tenant, enterprise SaaS travel platform — from the business requirements that shaped the design, through the technical decisions we made at each layer of the stack, to the DevOps pipeline that keeps language coverage growing automatically, and the in-context review tooling we built to close the quality loop.
