Anyone can code. But what differentiates a professional software engineer from a hobbyist coder is how well-designed and well-coded the final product is. Code quality is hard to come by. Unfortunately, most coders start straight without understanding basic concepts of software design. This course will help a budding coder, as well as an established programmer who wants to learn better design and write quality code.

It is really important that you grasp the core concepts of SOLID thoroughly. Once you get the fundamentals right, writing quality code will come naturally to you.There are tons of free YouTube videos on SOLID, but they try to teach you in bits and pieces, and don't pick the right analogies and code snippets. What you need is a holistic picture, which is what this course aims to provide. I have spent considerable time and effort to come up with the content for this course. Each and every concept, each and every analogy, each and every code example has been meticulously picked in such a way the design principles stick to your mind. I have used graphical illustrations and real world analogies wherever possible to drive home the point.
Something else that is special about this course - The subtitles are hand-scripted and accurate. I have even checked the timings to guarantee accuracy. Most courses come with subtitles that are auto-generated using a Speech-To-Text Engine, the accuracy of which is fairly low. But not mine. I have taken pains to script my course to perfection and include the subtitles too. So if you are at work, and you want to put me on mute, please feel free, although I would like you to hear my voice narration. If you want to put me on mute, just enable the subtitles in Udemy and play.

Such a course is relevant to someone seeking the role of technical lead. The course's emphasis on real-world analogies can help with communication.
Senior Developer
Senior Developer
A Senior Developer is responsible for designing, developing, and maintaining complex software systems. They often mentor junior developers and contribute to architectural decisions. This course can help someone become a Senior Developer because it focuses on writing quality code by learning design patterns. The course's live coding sessions and hands-on redesigning of existing code using SOLID principles provide crucial practical skills. Senior developers are expected to not only write code but also understand the design principles behind it. This course emphasizes real world analogies and code snippets, and goes over the concept of cohesion and coupling.
Software Engineer
Software Engineer
Software Engineers design, develop, and test software applications. They work on various aspects of the software development lifecycle. This course helps a software engineer by teaching them to write clean, well-designed code. The course emphasizes grasping core concepts of SOLID principles. The course's use of graphical illustrations and real-world analogies can drive home the point about good design and architecture. The course emphasizes breaking down the hierarchy and how to tell versus ask. The course may be particularly helpful due to the subtitles being hand-scripted and accurate.
Application Developer
Application Developer
Application Developers create and maintain software applications for computers and mobile devices. The course is useful for an application developer because it teaches how to write robust code.

The course emphasizes real-world analogies.
Backend Developer
Backend Developer
A Backend Developer focuses on the server-side logic and databases of web applications. Code quality is important in this role. This course may be useful to the backend developer because it teaches how to write maintainable code, which is invaluable on the backend. This course goes over real world analogies and code snippets to make its points. This course goes over the concept of inversion of control. The course goes over hands-on sessions where existing code is modified.
Frontend Developer
Frontend Developer
A Frontend Developer builds the user interface of web applications. This course may be useful in that it teaches how to write maintainable code. Furthermore, clean code is easier for other developers and designers to read. This course emphasizes graphical illustrations to help understand basic concepts. The course teaches what differentiates elegant code from badly designed code. The live sessions where existing code is analyzed and redesigned can be useful for a frontend developer.
Mobile Application Developer
Mobile Application Developer
A Mobile Application Developer creates applications for mobile devices. While mobile apps can be small, they also need to be well-designed. This course may be useful by teaching design principles and how to write extensible code. The techniques to identify violations may be particularly helpful to the mobile application developer. The restructuring of code to follow ISP may be particularly helpful to the mobile application developer.
Data Engineer
Data Engineer
Data Engineers build and maintain data pipelines and infrastructure. While designing data pipelines, it is important to heed software engineering principles. Data pipelines are essentially software applications. SOLID principles can apply to the way that data engineers design their pipelines. They should also follow existing conventions within their organization. This course may be useful by going over how to apply SOLID principles for writing quality code. This role typically requires a master's degree.
DevOps Engineer
DevOps Engineer
A DevOps Engineer automates and streamlines the software development process, including continuous integration and deployment. Cleanliness in code can translate to a better DevOps pipeline.
