Development of a High-Performance Cross-Platform Digital Banking Application Using React Native

A fast-growing fintech startup requires a highly performant, secure, and user-friendly mobile banking app to enhance user engagement, facilitate financial management, and support future scalability. The organization lacks internal development resources and needs a reliable partner to develop a cross-platform solution that meets their UX/UI standards and integrates seamlessly with backend APIs and identity verification services.

A mid-sized fintech startup focused on innovative digital banking solutions, targeting next-generation users with intelligent money management features and sustainability commitments.

• Create a high-performance, scalable mobile banking app compatible across Android and iOS platforms.
• Implement a reusable component library to ensure design consistency and accelerate development.
• Integrate with external APIs for banking operations, identity verification, and other third-party services.
• Achieve a shorter time-to-market with cost-effective development using a cross-platform framework.
• Ensure the app supports future feature additions, security enhancements, and compliance requirements.
• Deliver a product that improves user experience, increases user acquisition, and supports the client’s mission for sustainability and responsible banking.

• Reusable, styled component library to ensure consistency across all UI elements and facilitate rapid development.
• Implementation of onboarding and KYC verification processes using third-party identity verification tools.
• Integration with banking APIs for account management, transaction processing, and real-time data retrieval.
• In-app functionalities including budgeting, savings tools, and spending controls.
• Secure user authentication mechanisms, including biometric login and multi-factor authentication.
