Case Study: a leading global food and beverage company achieves a seamless app migration with Toptal

Fortune 500 Food and Beverage Company modernizes Xamarin app with Toptal for 100,000+ employees

The customer, a global food and beverage company, faced a critical challenge when its mobile app, built on Xamarin, reached end-of-life, risking future updates and app store submissions. Vendor Toptal was engaged to provide application migration and modernization services.

Toptal implemented a strategic migration to .NET MAUI, halting changes to the old codebase and moving screens individually to ensure no functionality loss. They also rewrote unstable native services for cross-platform stability. The outcome was a sustainable app platform that prevents obsolescence, with Toptal delivering improved performance and reliability through stability fixes and database optimizations.
