• Optimize performance:
  • Use caching, optimize database queries, and minimize the number of queries per request. Use django-debug-toolbar to identify performance bottlenecks.
• Write tests:
  • Django provides a powerful testing framework that allows developers to write unit, integration, and functional tests.
