This handles the scaffolding and performance work that comes up when you're building or scaling backend services. You get REST API boilerplate generation, database query optimization, and load testing setup so you're not starting from scratch each time. It's practical for when you need to spin up a new service quickly or when existing endpoints are getting slow under traffic. The focus is clearly backend infrastructure rather than business logic, which is the right split. Good for teams that want consistent API patterns and don't want to reinvent database indexing strategies on every project.
