Results Obtained 📈

The WorkingCapital platform effectively addressed the financial needs of its users, ensuring a smooth flow of capital and maintaining financial system stability.

👉 NestJS was chosen as the backend framework for the Loan and Invest platform due to its modular and scalable architecture, which perfectly suited the project's requirements.

👉 Notification system: To inform users about changes in the status of loans placed in the system.

👉 Simplified Login: Users can log in to the loan and investment platform quickly and conveniently by using their existing Google credentials, reducing the friction associated with remembering and entering a separate username and password.

👉 Querying and Filtering: PrismaJS offers a powerful query API that simplifies the process of retrieving and manipulating data from the database.

👉 Performance Optimization: PrismaJS offers performance optimizations through features like query batching and selective field retrieval. These optimizations reduce the number of database roundtrips and improve the overall efficiency of data retrieval operations. In a loan and investment platform, where large datasets and complex queries are common, these optimizations can have a significant impact on response times and scalability.

👉 Insert Data into Word Document: we've implemented to programmatically insert text into Word documents using Google Cloud Storage. This allows for dynamic text insertion and efficient document management within the platform.

👉 Investments flow: individuals or businesses can borrow funds from lenders and repay them over time with interest, creating a flow of capital from lenders to borrowers.

👉 Return of investments flow: within a specified timeframe along with the agreed-upon interest. This return of investments flow ensures that lenders receive their principal amount back and also earn a profit from the interest charged, while borrowers fulfill their financial obligations and maintain their creditworthiness. It plays a crucial role in maintaining the stability and sustainability of the financial system by facilitating the continuous circulation of capital for future investments and economic growth.

Commenting System: The project comments feature enables users to leave comments or feedback on specific project.

👉 KYC verification: a mandatory process for loan and investment platforms, requiring customers to provide identification and supporting documents to confirm their identity and assess their eligibility. This helps ensure the legitimacy of customers, prevent fraudulent activities, and comply with regulatory standards for secure lending and investing.

👉 Simplifying the process of transferring data onto a Word document.

👉 Handling substantial data and traffic volumes: Effectively managing and efficiently handling high volumes of data and traffic.

👉 Database optimization: Enhancing the performance of resource-intensive and frequently accessed queries.

👉 Data archiving: Preserving optimal system performance as time progresses.
