Get to know the tools of the software trade! Understand the fundamentals of good software design and development, from object-oriented principles to clean code guidelines. Once you have a solid foundation, get your hands dirty with sample programs that use software architecture and design patterns like MVC, factory, chain of responsibility, adapter, and many more. Every program will walk you step by step through a problem, its context, its solution, and relevant limitations. With information on creating good documentation and implementing best practices, this comprehensive guide will improve your applications!

Highlights include:

1. Object-oriented programming

2. Clean code

3. Design patterns

4. Software design principles

5. Application organization

6)Creation patterns

7. Structural patterns

8. Behavioral patterns

9. Data patterns

10. System architecture patterns

11)Cloud-native patterns

12)Documentation

Learn to use essential design patterns by following detailed code examples
