Optimizing Currency Exchange with a Scalable Mono Repo Architecture

Money4Travel is a comprehensive currency exchange platform designed to simplify transactions for both money exchangers and travelers. Built as a mono repo project, it consists of two key applications:
Exchanger App: A powerful dashboard where money exchangers can onboard, manage transactions, and streamline operations.
Traveler App: A Progressive Web App (PWA) that enables travelers to search for currency exchangers by postcode, compare live market rates, and make informed currency exchange decisions.
To ensure seamless functionality, real-time exchange rate comparisons, and optimized performance, we focused on building a robust, scalable, and maintainable architecture that enhances user experience and operational efficiency.

Project Challenges

Performance & Scalability

Managing two applications in a single monorepo could lead to performance bottlenecks as both apps scale. Ensuring that resource consumption is efficient and performance remains optimal as the apps grow can be a challenge.

PWA Optimization

Building a Progressive Web App (PWA) that provides a seamless, mobile-first experience while ensuring it works offline can be challenging. Ensuring the app’s performance even in low or no connectivity scenarios requires careful implementation of caching strategies and offline functionality.

Reusability & Maintainability

Developing reusable UI components and a modular architecture helps with keeping the codebase clean and scalable. However, it can be difficult to balance reusability with the need for customization, and keeping the codebase easy to maintain over time requires consistent design patterns and documentation.

Cross-platform Compatibility

Ensuring consistent behavior and look across various platforms (e.g., web, iOS, Android) can be challenging, especially when dealing with device-specific features and browser discrepancies. It requires thorough testing and optimization.

Data Synchronization

Keeping data in sync between the mobile app and backend, especially in offline scenarios, can pose a challenge. The system should handle seamless synchronization once the app goes online without data loss or inconsistency.

Security & Privacy

Securing both apps, especially in the context of PWA and mobile platforms, requires strong encryption, secure APIs, and robust user authentication. Ensuring user privacy while maintaining app functionality, particularly with offline access, is a critical challenge that needs to be addressed throughout the development lifecycle.

Our Solutions

  • Mono Repo with NX for Modularization Implemented NX to structure the mono repo, allowing shared components across both applications. Reduced redundancy and improved efficiency in development and maintenance.
  • Optimized Performance for the Progressive Web App (PWA) Ensured smooth mobile accessibility with offline support. Implemented service workers to cache essential assets, reducing load times.
  • Reusable Component Architecture Built a component library for consistency and faster development across the Exchanger and Traveler apps. Minimized code duplication and improved maintainability.
  • Real-Time Currency Rate Integration Integrated a live rate comparison feature, ensuring travelers always access up-to-date currency exchange information.
  • Enhanced Scalability with Cloud-Based Infrastructure Optimized backend infrastructure using Python to handle high volumes of concurrent requests efficiently. Ensured platform scalability to support future growth.
  • User-Centric Dashboard Development Created an intuitive, feature-rich dashboard for money exchangers to manage services efficiently.Improved user experience with responsive design and seamless navigation.
