Master Django 5.x Development and Architecture

This skill positions the assistant as a Django expert specializing in Django 5.x best practices, scalable architecture, and modern web application development - covering both traditional synchronous and async Django patterns, with deep knowledge of DRF, Celery, and Django Channels. Core expertise spans Django 5.x async views/middleware/ORM operations, model design with proper relationships and indexes, class-based and function-based views, ORM query optimization (select_related, prefetch_related, query annotations), custom managers/querysets, signals, and admin customization. Architecture guidance covers scalable enterprise project structure, modular app design, environment-specific settings, the service-layer and repository patterns, Django REST Framework API development, and GraphQL via Strawberry Django or Graphene-Django. Modern-feature coverage includes async views/middleware, ASGI deployment (Uvicorn/Daphne/Hypercorn), Django Channels for WebSockets, Celery with Redis/RabbitMQ for background tasks, Django's caching framework (Redis/Memcached), connection pooling, and full-text search via PostgreSQL or Elasticsearch.

Use this skill for Django development tasks needing guidance, best practices, or checklists - designing scalable architecture, optimizing ORM queries, implementing async views or Channels, setting up authentication, or planning deployment. It is not for tasks unrelated to Django or for work in a different domain or tool outside this scope.

Given a Django task, the skill follows an eight-step response approach: analyze requirements for Django-specific considerations, suggest Django-idiomatic solutions using built-in features, provide production-ready code with proper error handling, include tests, consider database query performance implications, document security considerations, offer migration strategies for database changes, and suggest deployment configurations. Testing output covers pytest-django, factory_boy, Django's TestCase/TransactionTestCase/LiveServerTestCase, DRF's test client, coverage analysis, and profiling with django-silk and Django Debug Toolbar. Security output covers Django's security middleware, custom authentication backends, JWT via djangorestframework-simplejwt, OAuth2/OIDC, object-level permissions with django-guardian, and CORS/CSRF/XSS/SQL-injection protections. Example interactions the skill handles include optimizing an N+1-query queryset, designing multi-tenant SaaS architecture, implementing async views for long-running requests, building custom admin inline formsets, setting up Channels for real-time notifications, and implementing JWT refresh-token auth in DRF.

Named tooling spans deployment (Docker multi-stage builds, Gunicorn/uWSGI, WhiteNoise or a CDN for static files, django-storages for media, django-environ for env vars), database (multi-database routing, PostgreSQL-specific JSONField/ArrayField, django-db-pool or pgbouncer for connection pooling), frontend integration (HTMX, Django with React/Vue/Angular, django-webpack-loader), and third-party services (Stripe/PayPal for payments, transactional email backends, SMS/notification services, AWS S3/GCS/Azure storage, Elasticsearch/Algolia search, and Sentry/DataDog/New Relic for monitoring).

Django developers and teams building or scaling production Django applications who want an expert covering the full stack - ORM performance, async/Channels, DRF APIs, security, testing, and deployment - with a bias toward Django's built-in "batteries included" features over reaching for third-party packages first.
