In my experience, writing clean code is more important than ever. Systems become more and more complex, more and more people are working on the same code base and languages provide more and more features. All this trends can easier be dealt with by keeping code simple, clean, well-tested and documented. Building well-designed systems is hard, but it is even harder to keep them that way while adding new features and ironing out bugs.
This is especially important in C++ where it is so easy to shoot yourself in the foot just because there are multiple ways to do so. Writing clean and modern C++ code is the key to contain the language's complexity and avoid common pitfalls associated with it.
I am here to share my experience and knowledge to help you write better C++ code, and develop coding habits to do so by default.
