Your portfolio project

A tested crowdfunding contract

Turn the exercises into a small repository another developer can run and review. Use a local chain or test network.

What to include

Contract source and reproducible setup instructions.
Tests covering expected behavior and failure cases.
A README explaining permissions, assumptions and known limitations.

Be ready to explain your design decisions and walk through a failing test. Course completion is a starting point; hiring requirements vary.
