+## 7. Technical Debt & Architecture
+
+### 7.1 What's Working Well ✅
+
+1. **Clean Architecture**
+   - Separation of concerns (models, services, API endpoints)
+   - Generic versioning system using ContentType
+   - FSM-based moderation workflow
+
+2. **Django Packages Used**
+   - `django-ninja`: Modern API framework (excellent choice)
+   - `django-fsm`: State machine for moderation
+   - `django-lifecycle`: Model lifecycle hooks
+   - `dirtyfields`: Track field changes
+
+3. **Database Design**
+   - UUID primary keys
+   - Proper indexing
+   - JSON fields for flexibility
+   - PostGIS conditional support
+
+4. **Code Quality**
+   - Well-documented models
+   - Type hints in API
+   - Consistent naming
+
+### 7.2 Areas for Improvement ⚠️
+
+1. **Empty Models**
+   - `apps/notifications/models.py` is essentially empty
+   - `apps/reviews/models.py` doesn't exist
+
+2. **Missing Services**
+   - Need service layer for complex business logic
+   - Edge Function logic needs to be translated to services
+
+3. **Testing**
+   - No Django tests found
+   - Need comprehensive test suite
+
+4. **Background Tasks**
+   - Celery not yet configured
+   - All Edge Function logic currently synchronous
+
+5. **Rate Limiting**
+   - Not implemented in Django yet
+   - Supabase has rate limiting tables
+
+### 7.3 Recommended Architecture Changes
+
+1. **Add Celery**
+   ```
+   django/
+     celery.py          # Celery app configuration
+     tasks/
+       __init__.py
+       notifications.py # Notification tasks
+       moderation.py    # Moderation tasks
+       maintenance.py   # Cleanup tasks
+       auth.py          # Auth tasks
+   ```
+
+2. **Add Service Layer**
+   ```
+   django/apps/*/services/
+     __init__.py
+     business_logic.py  # Complex operations
+     email.py          # Email sending
+     notifications.py  # Notification logic
+   ```
+
+3. **Add Tests**
+   ```
+   django/apps/*/tests/
+     __init__.py
+     test_models.py
+     test_services.py
+     test_api.py
+   ```
+

+
+## 8. Estimated Timeline
+
+### Minimum Viable Migration (Core Features Only)
+**Timeline**: 3-4 weeks
+
+- Phase 1: Critical User Features (2 weeks)
+- Phase 2: Enhanced Data (1 week)
+- Phase 5: Background Tasks (1 week)
+
+**Result**: Feature parity for 80% of users
+
+### Complete Migration (All Features)
+**Timeline**: 6-8 weeks
+
+- Phase 1: Critical User Features (2 weeks)
+- Phase 2: Enhanced Data (1 week)
+- Phase 3: Moderation & Admin (1 week)
+- Phase 4: Account & Compliance (4 days)
+- Phase 5: Background Tasks (1 week)
+- Phase 6: Content & Analytics (1 week)
+- Testing & Polish (1 week)
+
+**Result**: 100% feature parity with Supabase
+
+---
+
+## 9. Risk Assessment
+
+### High Risk
+1. **Notification System Migration**
+   - Currently using Novu (third-party service)
+   - Need to replace with Django + Celery + email/push provider
+   - Risk: Feature gap if not implemented properly
+   - Mitigation: Implement core notifications first, enhance later
+
+2. **Background Task Migration**
+   - 42 Edge Functions to migrate
+   - Complex business logic in functions
+   - Risk: Missing functionality
+   - Mitigation: Systematic function-by-function migration
+
+### Medium Risk
+1. **Data Migration**
+   - No existing data (stated: "no data to be worried about")
+   - Risk: Low
+
+2. **Frontend Integration**
+   - Frontend expects specific Supabase patterns
+   - Risk: API contract changes
+   - Mitigation: Maintain compatible API responses
+
+### Low Risk
+1. **Core Entity Models**
+   - Already implemented
+   - Well-tested architecture
+
+2. **Authentication**
+   - Already implemented with JWT, OAuth, MFA
+   - Solid foundation
+
