Mission 11 of 12

The AI Native Builder - Build Your Capstone

Your capstone. Scope a real product, then build it end to end - frontend, backend, database and a real AI feature - directing AI tools as your teammates the whole way.

By the end of this mission: “I can scope a product into an MVP and build a full-stack, AI-native app end to end.”

What you learn, checkpoint by checkpoint

  1. Checkpoint A

    Scope the MVP and set up the full-stack skeleton

    • Write a product spec with user stories and define the smallest useful MVP
    • Pick your stack and set up the full-stack skeleton (frontend, API, database)
    • Plan the build order so the most important feature ships first

  2. Checkpoint B

    Build the core features, data model and AI feature

    • Build the database schema, auth layer and core data model
    • Ship the primary feature end to end through the full stack
    • Add a real AI feature and handle its output responsibly

  3. Checkpoint C

    Test, harden and ship to production

    • Add error handling, tests and polish throughout the app
    • Wire CI/CD and deploy to production on a real domain
    • Record a demo walkthrough and write the capstone case study

AI companion mode · AI as Product

AI runs inside what you build

AI lives inside the product you build. Treat its output as untrusted - handle errors, evaluate quality, design for uncertainty.

What proves you’re done

Deployed capstone MVP + case study draft

Every mission ships something real and public. If you can’t explain it, you can’t submit it.

Free · no card needed

Reading is not building.
