🔐 Security Review

Authentication & Authorization

✅ Strong Points:

JWT tokens with proper expiration
Password hashing with bcrypt (12 rounds)
Role-based access control (USER, ADMIN, FINANCE)
Protected routes with HOC pattern
CORS configured (needs production tuning)

⚠️ Production Considerations:

Rate limiting needed (prevent brute force)
CSRF protection for forms
Input sanitization (XSS prevention)
HTTPS enforcement
Secret key rotation strategy

Data Protection

✅ Strong Points:

Passwords never stored in plain text
JWT payload minimal (only email)
Role checks on all admin endpoints
SQL injection protected (Supabase client)

📈 Performance Review

Backend Performance

Metric	Expected	Notes
API Response Time	<100ms	Supabase is fast
JWT Verification	<10ms	In-memory
Image Upload	<2s	Depends on storage
Fraud Check	<50ms	In-memory checks

Frontend Performance

Metric	Expected	Notes
Initial Load	<3s	Next.js optimization
Page Transitions	<500ms	Client-side routing
Form Submission	<2s	API dependent

Optimization Opportunities:

Image compression before upload
Lazy loading for admin dashboard
Service worker for offline support
Code splitting (already partial with Next.js)
