Layered Architecture: From Zero to a Working Application


Description

Introduction

Welcome to the course! If you’ve ever felt like your codebase was becoming a "spaghetti" mess where a single UI change breaks your database connection, you’re in the right place.

This course is designed to transform you from a coder into a software architect. Our primary mission is to master Layered Architecture: the industry-standard antidote to development chaos. By the end of this journey, you won't just be "writing code"; you'll be engineering professional-grade systems that are modular, testable, and built to last.

Core Course Objectives

By the end of this course, you will be able to:

  • Deconstruct complex applications into isolated, functional layers.
  • Enforce the principle of "Separation of Concerns" to prevent code leakage.
  • Implement a full-stack application using a decoupled architectural blueprint.
  • Architect data models and access patterns that survive technology shifts.

Layered architecture isn't about writing more code; it's about writing smarter code. You are building a structure where every component has a home and every bug has a place to hide, and you'll know exactly where to find it.
