A Django developer worth hiring understands the ORM well enough to never write raw SQL for standard operations, writes migrations that can be safely rolled back, and keeps DEBUG = False in production without being told. Expect to pay $20–50/hr for experienced offshore developers, $90–150/hr for US-based senior Django work. Here's how to tell the difference in a 30-minute interview.
What Makes a Django Developer Different from a Python Developer
Python is the language. Django is an opinionated framework with its own patterns, conventions, and failure modes. A developer can have five years of Python experience and still be a beginner in Django — the ORM has a learning curve, the migration system has subtle rules that bite you in production, and the admin, authentication, and permissions systems all have Django-specific depth.
When you post for a "Python developer," you get people who have written scripts, data pipelines, and Flask APIs. Most of them have touched Django at some point. Very few have maintained a Django application through multiple schema migrations, performance issues, and security requirements in production.
Ask specifically for Django experience. Then verify it.
The Django-Specific Skills That Predict Success
ORM proficiency — not just querying, but performance
The Django ORM is powerful and easy to misuse. The most common and expensive mistake is the N+1 query problem: a view that makes one query per related object instead of one query for all of them. Without optimisation, iterating over 100 orders and accessing order.customer.name on each one fires 101 queries — one to fetch the orders, then one per order to fetch each customer row. On a page with 50 results, that's 51 database round-trips instead of 1.
A developer who knows the ORM deeply uses select_related() for foreign keys (which generates a SQL JOIN and returns both tables' columns in a single query) and prefetch_related() for many-to-many and reverse foreign keys (which runs a second query with an IN clause like WHERE author_id IN (1, 2, 3, ...) and joins the results in Python memory). The distinction is: select_related reduces query count to 1 but increases column count in the result set; prefetch_related uses 2 queries but avoids JOIN row multiplication on large related sets. On a ManyToManyField, select_related cannot be used at all — only prefetch_related applies.
Ask: "When would you use select_related instead of prefetch_related?" The correct answer is not "it depends" without elaboration — it's a specific explanation of what SQL each generates and why that changes the performance profile for different access patterns.
Migration safety
Database migrations are where Django projects get hurt in production. The risk is not writing migrations — Django handles that automatically. The risk is writing migrations that lock tables under production load, or that cannot be rolled back if something goes wrong at 2 AM.
A senior Django developer knows: data migrations and schema migrations should be separate; RunPython functions that process entire tables should batch to avoid memory issues; adding a NOT NULL column to a large table requires three migrations (add nullable, backfill, add constraint), not one.
The reason this matters: PostgreSQL takes an ACCESS EXCLUSIVE table lock when altering a table's schema. While that lock is held, every query against that table — every SELECT, INSERT, UPDATE — is blocked and queued. On a table with 10 million rows, a migration that adds a NOT NULL column with a default and rewrites all existing rows can hold that lock for 30–60 seconds. To a production application, this looks like a complete outage. Developers who have never maintained a production database under load do not know this intuitively — they learn it after causing an incident.
Production settings discipline
Django ships with a settings.py that is configured for development — DEBUG = True, SECRET_KEY hardcoded, ALLOWED_HOSTS wide open. Every single one of those defaults is a security risk in production. A Django developer who has deployed production applications has a standard pattern for this: separate settings files (or environment variables), SECRET_KEY and database credentials loaded from the environment, ALLOWED_HOSTS set explicitly, DEBUG = False.
If a developer you are considering has a public GitHub repository with a Django project and DEBUG = True in any settings file committed to the repository — that is not a beginner mistake, it is evidence of production habits you do not want.
Django REST Framework (DRF) when you need an API
Most Django projects today include an API. DRF is the standard library for this, and it has its own depth: serialiser validation, viewsets versus APIViews (and when to use each), throttling, custom permissions, nested serialisers. A developer who has only used the generic viewsets without customising permissions or writing custom serialiser logic has not used DRF in a non-trivial application.
The One Question That Separates Junior from Senior
"Walk me through a migration you wrote that had to be backward-compatible with the existing production schema."
Junior developers describe adding a field to a model and running makemigrations. Senior developers describe a specific situation: a column that needed a default value on a table with 2 million rows, or a field type change that required backfilling data before dropping the old column, or a migration that had to be reversible because a rollback was possible. If they cannot give a specific example with the constraints they faced, they have likely never maintained a production database through a non-trivial schema change.
The detailed vetting questions — all ten of them with what to listen for — are in How to Vet a Django Developer.
Red Flags Specific to Django Developers
DEBUG = True in any production or staging settings file. This exposes your full stack trace, settings values, and database queries to anyone who triggers an error page. It is not a misconfiguration to overlook — it is evidence that the developer has not deployed a Django application under real conditions.
Raw SQL for queries the ORM handles.cursor.execute("SELECT * FROM users WHERE id = %s", [user_id]) instead of User.objects.get(id=user_id) is not inherently wrong — raw SQL has legitimate uses for complex queries. But using raw SQL for standard CRUD operations is a signal the developer does not trust or understand the ORM, which means the codebase will be harder to maintain and harder to migrate.
A single models.py with more than 200 lines and no splitting. Django allows (and encourages) splitting models across multiple files in a models/ package. A project where all models are in one file that has grown past 200 lines is a project that the developer is not structuring for maintainability.
No custom model managers or querysets. Complex query logic repeated across views instead of encapsulated in a custom manager is a maintainability problem. Not every project needs custom managers, but a developer who has never used them has probably not built anything complex enough to need them — which is useful information about the scale they have worked at.
Celery tasks that are not idempotent. A background task that sends an email or processes a payment and does not check "has this already been done?" before acting will cause double-charges or double-emails when tasks are retried after a worker failure. Ask specifically: "How do you make a Celery task safe to retry?"

Where to Find Django Developers
Toptal — pre-vetted pool, expensive, reliable for senior Django work without screening overhead.
Upwork — large pool, large variance. Works for short fixed-scope projects if you run your own technical screen first.
Django community job boards — djangojobs.net, Django Forum jobs category. Developers here are specifically Django-focused, which narrows the search usefully.
Direct referral — the best Django developers are usually not actively looking. Ask Django developers you know who they'd recommend.
I take on Django projects as a freelance developer — backend APIs, SaaS applications, integrations, and code reviews. See my rates and availability.
Frequently Asked Questions
How long does it take to hire a Django developer? With active sourcing and a clear spec, 2–4 weeks to a paid trial start. The technical screen is one call; the trial project adds another week. Do not skip the trial — interviews reveal what the developer knows, trial projects reveal how they work.
Do I need a Django developer or a Python developer? If you are building a web application, ask for Django specifically. A Python developer without Django experience will need months to be productive on a web backend. The framework knowledge — ORM patterns, migration habits, deployment configuration — does not transfer from general Python work.
Should I hire a junior Django developer to save money? A junior Django developer is appropriate when you have a senior developer or CTO who will review their work and catch issues before they reach production. Without technical oversight, a junior Django developer will produce code that appears to work and accumulates technical debt that takes months to unwind. The false economy of junior rates is a real pattern.
Can a Django developer also handle the frontend? Some Django developers have frontend skills (React, Vue, or even Django templates). Most are backend specialists. If you need both, ask explicitly — and be prepared to pay for both skill sets. A Django developer who describes themselves as "full stack" should be able to show you frontend work they have shipped, not just say they know React.
What is the difference between Django and Django REST Framework (DRF)? Django is the web framework. DRF is a library built on top of Django that makes it easier to build REST APIs — it adds serialisers, viewsets, authentication classes, and a browsable API interface. Most modern Django projects that expose an API use DRF. If your project is API-first, ask specifically about DRF experience.
