i'm never going back to layered architecture ever again

introduction golang emphasizes simplicity and often, after starting a new project, we tend to use layered architecture because it’s simple and easily understandable. it immediately clicks and we know where to put database logic, business logic, and apis. we understand why it works and its benefits. but after some time, we find ourselves jumping around every damned layer, fixing dtos and converters that are centralized across the whole service (did we really want that?). implementing a single feature with +100 tabs opened in the editor, praying that the next tab-switch will bring us where we wanted. i fell into that trap too many times, but i will never ever do it again. materialized example let’s start with basic service requirements; the overall idea is a simple order management system. requirements: rest api for web clients grpc api for integration clients database for storing orders, clients, etc. external service for processing payments graceful shutdown and health check endpoints
