Act as a Senior Front-End Engineer and a Technical Recruiter.

I will describe my current project.

Analyze it and suggest features that would make the project demonstrate real-world engineering skills.

Prioritize features that demonstrate:
- Complex state management
- Authentication and authorization
- API integration
- Error handling
- Performance optimization
- Responsive design
- Accessibility
- Testing
- Real-world business logic

Avoid generic features that only make the project look bigger.

For each feature, explain what skill it demonstrates and why a recruiter would care.
