Good project ideas share these traits:
Solves a real problem: Something you or others would use
Shows relevant skills: Matches your target job (React roles need React projects)
Has enough depth: More than CRUD, less than a startup
You can explain it: You understand every line of code
Strong examples:
- A tool that solves a problem from your previous career
- A clone of a real product with your own twist
- An app that combines - APIs in interesting ways
Weak examples:
- Todo apps, weather apps, calculator apps
- Exact tutorial recreations
- Projects you can't demo or explain
