Case Study: a US-based financial technology company unifies its 26M-user BNPL platform with GSPANN's AI-assisted React Native migration

a 26M-user BNPL platform unifies mobile apps with GSPANN and reaches 99.89% crash-free rate

The client, a 26-million-user BNPL platform, faced operational challenges from maintaining separate native iOS and Android apps, which led to duplicated effort and platform drift. They needed to unify their codebase to accelerate feature delivery and ensure a consistent experience. GSPANN was engaged to assist with a large-scale React Native migration.

GSPANN contributed a team that executed a hybrid migration, moving 189 screens into a single codebase. They embedded AI-assisted development using tools like Cursor and Claude Code to accelerate the process. The solution resulted in a highly stable app with a 99.89% crash-free rate for Android and successfully unified the platform for their 26 million users.
