Build With AI

This is where the app actually gets built. With a clear specification and a defined database, an AI coding agent stops guessing and starts executing. The goal isn't to generate everything in one giant prompt — it's to build the same way an experienced engineer would: incrementally, with each feature tested before moving to the next.

What you'll do

Create your repository and establish the project structure

Create your database from the schema you designed in Step 3
Implement features incrementally, one at a time
Test each feature as it's built
Commit changes to GitHub as you go
