---

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
