AI coding agents are changing how developers think about software design, but they don't replace the need for architectural judgment.
In this course, you'll learn the principles and patterns behind maintainable code (SOLID, DRY, KISS, YAGNI, Gang of Four patterns, and layered architecture) and use AI as a collaborator to apply them in full-stack Node.js codebases. You'll develop the judgment to recognize when code violates a principle, choose patterns that fit the problem, and decide when an AI agent's suggestion actually improves the design. By the end, you'll be able to design layered applications, apply patterns within each layer, and refactor existing code with deliberate trade-off reasoning.
