What will I learn?

Mastering Object-oriented Programming Course teaches you to design clean, extensible systems through a realistic FreelanceManager app. You will model clients, projects, billing, invoices, and time tracking using classes, inheritance, interfaces, and polymorphism, then apply SOLID, testing strategies, error handling, and refactoring patterns to deliver maintainable, well-documented, production-ready code.
