CQRS is usually shown as the pattern that adds too much overhead. People wrongly assume that it can be used only in enterprise projects. In a nutshell, CQRS is a structural pattern that shows how to structure your architecture.

I show how to start with the classical layered CRUD monolith and, step by step, go to the CQRS, explaining that you don’t need multiple databases, event sourcing and fancy tech stack. What you need is the focus on the business and slice your architecture vertically to get more explicit and straightforward code.
