⚠️ Known Limitations

Intentionally Not Implemented (Out of Scope)

Authentication/Authorization
- Status: Not implemented
- Reason: Demo platform, adds complexity
- Future: JWT tokens with python-jose (already installed)
Redis Caching
- Status: Configured but not active
- Reason: Performance adequate without it
- Future: Easy to enable for scale
Real ML Models
- Status: Rule-based scoring instead of trained models
- Reason: No training data available
- Current: Functional predictions (78% accuracy claim)
Report Generation (PDF/Excel)
- Status: Endpoint exists but not implemented
- Reason: Time constraint, not critical for demo
- Future: Use ReportLab or XlsxWriter
Test Coverage
- Status: 0% unit test coverage
- Reason: Prioritized working features
- Future: Add pytest tests for critical paths

🎓 Lessons Learned

Start with Real Data Early - Mock data causes technical debt
SQLAlchemy Async is Tricky - Required careful query construction
Railway is Fast - Simple deployment but needs proper configuration
TypeScript Strictness Helps - Caught frontend issues early
Structured Logging Essential - Made debugging much easier
