What you will learn

Leverage SOLID principles to craft clean, extensible and maintainable software systems

Discover the intricate and less known details of SOLID principles

Understand the scope and the trade-offs associated with each SOLID principle

Adopt the best practices of Object-Oriented Design and Architecture in your work

Refine your skills for interviews targeting Senior Developer, Architect, and Tech Lead roles

Make software development more enjoyable for yourself!

Description

SOLID principles are a set of architectural guidelines that help you craft clean, extensible, and maintainable systems. Mastering the SOLID principles gives you a set of skills to produce the highest-quality software.

With this course, you'll go beyond just writing code to become a software designer. If you aspire to roles such as senior developer, architect, or tech lead, then the material in these lectures will be very useful for you. Additionally, the deep insights into the world of Object-Oriented Design that you'll acquire here will make programming much more enjoyable!

SOLID is an acronym that stands for five core principles of Object-Oriented Design and Architecture:

  • Single Responsibility Principle

  • Open Closed Principle

  • Liskov Substitution Principle

  • Interface Segregation Principle

  • Dependency Inversion Principle

These principles embody more than 40 years of academic research and industry experience, passed to us from the previous generations of developers.

While each of SOLID principles can be described in one sentence, they are far from being simple to apply in practice. In this course, you will learn how to use SOLID principles in your own projects. I'll explain all the complex topics in simple words, using real-world examples, so you'll have very smooth and enjoyable learning experience.

You'll also discover many interesting historical facts about the people behind the SOLID principles and the software architecture. This historical background will allow you to see the bigger picture, and make the course more colorful and engaging.

It's not an overstatement to say that learning SOLID principles will open a new dimension of software development for you. So, I invite you to join me on this exciting journey into the depth of SOLID principles of Object-Oriented Design and Architecture!

I'm working with C#, even some courses are in Java, but I understand the general principle of it. Very useful to create a future-proof product

A clear course on SOLID principles. Although some stay not quite clear to me, they become clearer and I think Experience is my next step. Let's go coding ! Thanks

Great explanation for all the principles individually. I can clearly say that now my understanding of the principles is more refined, especially w.r.t. LSP. Thanks Vasiliy ! Great job and keep up the good work.

Great course with details explanation for each lesson. I'd love to have your code examples and UML examples that you used to present in the course. It's be so useful to comeback and view them later in my local PC. So please consider to upload the materials as resources of the course. Thank you ^^

The course was great, I had a hard time understanding most of the concepts of SOLID, and now I think I have a great foundation to start implementing these concepts in my work. However, as a warning for whoever is considering buying this course, the content is primarily theoretical and it doesn't have hands-on exercise, not that I think giving the topics is needed, and also that will constraint you to use a specific language; but seeing other reviews I notice is something some users are expecting. In the end, the content is top-notch and the explanations were very clear and with examples, I think for anyone that is having a hard time understanding the principle or seeing how to apply them, this course is a must-have.

The instructor very effectively explains the concepts and relates them to real-world applications. This course covers important concepts that are not well covered in most academic curricula but significantly impact software development business deliverables when applied.

Overall i liked the course. Would have been awesome if we had a small working example of an app demonstrating these concepts together.

This course is an excellent way to start working with SOLID principles. It has a very complete approach with theoretical definitions, explanations that enforce understanding, and real-life examples.

The concepts are well explained, but very slow paced, could do with bit more hands-on to make the course more engaging.

In general, the course is well structured and clear to some extend. However, I think it would be worth it to developed an application through the course in order to have some hands-on exercises. Thank you so much for sharing.

Explaination is good with some humor . Summary at the end of every section is the best part. I can revisit this anytime . Thanks a ton.
