Challenges Faced:

• MongoDB: MongoDB, despite its advantages, presents several challenges for developers. Designing an efficient schema requires careful consideration to balance flexibility with performance. Scaling MongoDB horizontally brings complexity in managing distributed environments and ensuring data consistency. Optimizing queries and indexing is crucial for performance, especially with large datasets. Handling transactions and ensuring ACID compliance can be challenging, especially in distributed setups. Managing MongoDB operations, including backups, upgrades, and security configurations, demands expertise and resources.
• React Native: React Native, while a powerful framework for cross-platform app development, comes with its own set of challenges. Managing platform differences can be tricky, as certain features and behaviors may vary between iOS and Android devices.
• Comprehensive Testing: Multiple aspects of the system implementing diversity in general, as well as collectibles, and referrals were considered as potential problems. There were test drives that revealed some problems which were then ironed out before the solution went live.
