Challenges

Tight timeline for a full-scale cross-platform digital bank launch 

After obtaining a digital banking license, our client faced the ambitious task of launching a complete digital banking platform within three months. The challenge required rapid development, seamless integration with existing systems, and strict adherence to financial regulations. Time was of the essence, and our client’s success hinged on deploying a functional, compliant, and user-friendly solution within this compressed timeframe.

Scalability for millions of users 

With a user base in the tens of millions, the digital bank needed an infrastructure capable of handling high volumes of concurrent transactions. This required a robust, scalable system ensuring fast, reliable performance without downtime. The solution also needed to cater to diverse user needs, from retail customers to businesses, all while maintaining exceptional reliability and responsiveness.

Delivering an innovative, native-like experience 

In a competitive market dominated by traditional banks, the client’s app needed to offer a superior user experience. Security, speed, and innovative features were essential to attract and retain users while building trust in the platform’s ability to handle sensitive financial data. Achieving this required an agile development strategy to meet evolving user expectations and demands.

Solutions

Efficient cross-platform banking app development 

We adopted a modular cross-platform approach to streamline development and accelerate delivery. By leveraging Flutter, we achieved up to 90% code reuse across iOS and Android, reducing engineering effort by 60%. This approach enabled rapid feature implementation and testing through tools like hot reload for instant code previews. Critical banking functionalities, such as cryptocurrency transactions, savings modules, and Buy Now Pay Later (BNPL) options, were developed and seamlessly integrated into the app’s architecture.

Backend excellence for seamless performance 

To support millions of users, we built a robust backend using Node.js, designed to handle rapid transaction processing and ensure secure interactions with external services. The modular architecture enabled easy scaling and allowed for the swift rollout of updates and new features, ensuring uninterrupted operations.

End-to-end development and UI redesign 

Our team of 30+ experts managed every development stage, from mobile app creation to security audits and consulting. A key milestone was revamping the app’s UI to align with the brand’s vision, ensuring a seamless transition for existing users. The redesigned interface combined intuitiveness with the client’s new identity as a digital banking leader.
