💻 Code Architecture & Future Vision 🧬

Current Architecture: Procedural / Functional Programming

The entire project is currently built using Procedural Programming (Functional Programming), focusing on modular functions, structured data, and clean control flow. This approach was essential to master the logic and data flow of the banking system.

Future Evolution: Transition to OOP

This project serves as a solid foundation for my upcoming development phase. I am planning to refactor the entire system into Object-Oriented Programming (OOP), utilizing Classes, Inheritance, and Polymorphism. This will significantly improve scalability, code reusability, and maintainability for future banking modules.
