Hire Django developers who ship clean APIs and safe migrations

• Standing up a Django REST Framework backend that a React, Next.js, or mobile client consumes, with token auth, pagination, filtering, and versioned endpoints.
• Rescuing a Django app that got slow: killing N+1 queries with select_related and prefetch_related, adding the right database indexes, and unwinding migrations that lock large tables in production.
• Moving heavy work off the request cycle into Celery, such as report generation, email sending, webhook processing, and third-party syncs, with retries and idempotent tasks.
• Building an internal operations or back-office tool on the Django admin, with custom actions, permissions, and audit trails, without a separate front-end build.

Every engineer we put forward is screened by a senior Grape5 engineer before you meet them. For Django developers, we look specifically at:

• Can they read a slow endpoint and find the N+1 in query logs or Django Debug Toolbar, then fix it with select_related, prefetch_related, or annotate rather than more Python loops.
• DRF serializer judgment: when to use ModelSerializer versus explicit serializers, how they handle nested writes, validation, and avoiding accidental over-fetching or exposing fields.
• Migration safety on real tables: writing reversible migrations, splitting schema from data migrations with RunPython, and avoiding operations that hold long locks on a busy Postgres database.
• Celery task design: making tasks idempotent, setting retry and timeout policy, not passing ORM instances as arguments, and reasoning about what happens when a worker dies mid-task.
• Security defaults: leaning on the ORM to prevent SQL injection, keeping CSRF protection on, running DEBUG off in production, and handling secrets and settings per environment instead of hardcoding.
