Data modelling
Schema design, relationships, constraints and indexing built around how the business actually reads and writes data.
Django & Backend
Django & Python Backend Development
The backend is where a product either scales or quietly rots. I design data models that match the business, APIs that are predictable to consume, and permission systems that hold up when someone tries the URL directly.

Sound familiar?
- Queries got slower as data grew and nobody knows which ones
- Permissions are enforced in the interface, so the API is wide open
- Business logic is scattered between views, templates and the frontend
- Long-running tasks block requests and time out
Describe the data and the rules around it. That is usually enough for me to sketch the model.
What you get
Concrete deliverables, not a retainer with vague scope.
REST API design
Consistent resources, pagination, filtering, validation and error shapes that a frontend developer can work with without guessing.
Authentication and permissions
JWT or session auth, role hierarchies and object-level permissions enforced server side.
Background processing
Celery and Redis for exports, imports, notifications and anything that should never happen inside a request.
Query optimisation
Profiling, index tuning and caching to fix the specific queries causing the slowdown.
Deployment
Dockerised setup, environment configuration, migrations and a deploy path that is repeatable.
How it runs
- Step 1
Domain review
Understanding the entities and rules before touching the schema.
- Step 2
Schema and migrations
Models, relationships and a migration path that does not require downtime.
- Step 3
API layer
Endpoints, serialisation, validation and permissions, documented as they are built.
- Step 4
Async and integrations
Background jobs, third-party services and scheduled work.
- Step 5
Hardening
Load-sensitive query tuning, error handling, logging and deployment.

Read case studyDjango & Backend — questions
Do you build APIs for mobile apps as well as web?+
Yes. A well-designed REST API serves web, mobile and third-party integrations from the same contract — that is the point of designing it properly.
Can you improve an existing Django project?+
Yes. Common work includes fixing N+1 queries, adding missing indexes, moving heavy work to Celery, tightening permissions and untangling business logic from views.
PostgreSQL or MySQL?+
I use both in production. PostgreSQL is my default for new projects because of its data types, constraints and query planner. If your team already runs MySQL well, staying there is usually the better call.
Do you handle deployment and DevOps?+
I handle Dockerised application deployment, environment configuration, migrations and CI-friendly setups. For large-scale infrastructure I work alongside your DevOps team rather than replacing them.
