FAQ

Frequently Asked Questions

Explore common questions about the architecture and features of the SPK Financial Services platform.

React.js is ideal for financial dashboards due to its ability to efficiently manage and render large, dynamic datasets. Its component-based architecture allows us to create interactive charts, tables, and forms that update in real-time without reloading the page, providing a fast and seamless user experience.
Security is paramount in FinTech. DRF, built on Django, offers a robust set of built-in security features, including protection against common threats like CSRF and SQL injection. Its powerful authentication and permissions system was perfect for implementing the granular role-based access control needed for this platform.
For financial applications, data integrity is non-negotiable. PostgreSQL is renowned for its strict adherence to ACID principles, ensuring transactional reliability. Its ability to handle complex queries and its extensibility make it a superior choice for storing and managing sensitive financial data where accuracy is critical.
The calculator is a custom module built into the backend. It takes the principal amount, interest rate, and loan term as inputs. For each payment period, it calculates interest on the outstanding principal balance, which decreases over time. This automates a complex process, eliminates human error, and generates accurate amortization schedules instantly.
