PrePay's Solution enables anyone to have a digital account
Introduction
Emyoli’s work on the PrePay Fintech platform revolutionized the way users manage their finances. PrePay offers a cutting-edge digital wallet that allows users to effortlessly send and receive money in multiple currencies.
With the convenience of a physical debit card, users can pre-load funds and make purchases just like with a regular debit card. The platform also offers comprehensive reports and payment histories, empowering users with full control over their financial activities. Recognizing the potential for growth in the B2B sector, PrePay enlisted Emyoli’s expertise to develop a robust B2B solution as an extension of their already successful B2C platform. The goal was to create an MVP version in just three months that would form the foundation for the B2B platform while seamlessly integrating with the existing services.
Description
Emyoli embraced the challenge of building a robust digital B2B platform for PrePay. The comprehensive solution included a web admin area for clients and a super admin area for PrePay managers, along with feature-rich mobile apps for both Android and iOS. With this B2B platform, businesses gained the ability to provide their employees with customized debit cards, conveniently load them with funds, and track expenses during business trips. The platform also facilitated the uploading of receipts to the PrePay cloud for easy expense management and reporting. Integration with third-party services like I2C and other finance-related providers ensured a smooth and efficient experience for PrePay’s clients.
Technical Challenges
The project presented several technical challenges for Emyoli. One major hurdle was the tight timeline of three months to deliver an MVP version with a wide scope of functionalities. Moreover, effectively integrating with the existing services from the B2C platform required meticulous planning and execution. Communication and synchronization with different stakeholders within the PrePay team, including the CEO, CTO, Product Manager, developers, and B2C team leaders, demanded clear and concise communication channels.
Technology Stack
The technology stack utilized for the PrePay B2B platform included PHP over the Laravel framework for the backend, Mongo DB and Postgres DB for databases, Docker files for containerization, and lambda functions for serverless computing. CI/CD was managed using Jenkins. On the frontend, Vue.js and React Native were employed for developing the web and mobile applications, respectively. AWS served as the cloud provider for scalability, reliability, and security.
