The Node.js backend serves as the core of the platform, handling user authentication, goal creation, investment simulations, and data processing. It communicates with financial data APIs, user data, and historical investment performance databases.

Redis is used in the Node.js backend as a caching layer to store frequently requested data and reduce the load on the primary database. This enhances the performance of the system, particularly for users retrieving real-time stock prices, asset allocation strategies, and market simulations.

• Goal-Based Investment Planning: Users can define multiple financial goals, each with unique settings for time horizons, risk levels, and monthly contributions. The system dynamically adjusts investment strategies based on real-time market conditions, changes in user contributions, or changes in market trends.
• Real-Time Data Fetching and Caching: By leveraging Redis as a caching layer, the platform ensures that users can retrieve up-to-date stock prices, asset performances, and market trends without significant delays. Redis also stores session data, enabling a smoother user experience.

• Performance & Scalability: Node.js provided the platform with asynchronous, non-blocking capabilities to handle high loads and serve multiple requests simultaneously. 

  Redis reduced database hits, especially for real-time stock prices and portfolio information, significantly improving app response times.
• Personalized Investment Recommendations: The Node.js backend uses advanced algorithms and real-time data to suggest portfolio adjustments based on user-defined financial goals. As market conditions change, Redis caches real-time data for the most frequently traded stocks and assets, reducing the lag between data fetch and recommendation generation.
• Cross-Platform Accessibility: Using Ionic 6, the app provides a consistent, native-like user experience across iOS and Android. It allows users to manage their investments on the go, from goal setting to portfolio monitoring.
