Clean Code in Laravel: Implementing the Service Pattern for Scalable SaaS 🧼

The Problem: The Dreaded "Fat Controller" As full-stack developers building complex industrial platforms or scalable B2B applications at Smart Tech Devs, we inevitably face the problem of logic bloat. In a typical Laravel application, developers often start small, placing database interaction, validation logic, external API calls, and business logic directly inside the Controller's store() or update() methods. This approach works fine initially, but as requirements grow, these methods become monstrous, violating the Single Responsibility Principle (SRP).
