3. Money Transfer

  • Peer-to-Peer (P2P) Transfers: Send money to other users within the app.
  • International Transfers: Seamlessly transfer funds across borders.

  • Low Balance Alerts: Warn users when their balance falls below a specified threshold.

6. Optimization and Scalability

  • Microservices Architecture: Divide the app into smaller, independent services for scalability.
  • Load Balancing: Distribute traffic efficiently across multiple servers.
  • Caching: Cache frequently accessed data to reduce database queries.

7. Fast Data Fetching
