Have you ever started coding a feature, only to realize halfway through that your architecture is hopelessly tangled? We’ve all been there. You start writing a service, and before you know it, your business logic is heavily bleeding into your database queries and third-party APIs. To prevent this architectural chaos, modern engineering teams are increasingly turning to Spec-Driven Development (SDD) . What is Spec-Driven Development? Spec-Driven Development is a paradigm where you define the "Wha
