Python Development Services
Django, FastAPI & AI backends
DanixSoft builds Python back ends — Django web platforms, FastAPI services, background jobs, and the APIs behind AI features — for startups and businesses that need typed, tested, containerised code their team can maintain.
From Django platforms with a full admin to FastAPI services that sit behind AI features, our Python work is built to be maintained: typed, tested, containerised, and documented. Python is also the backbone of most of the AI features we ship.
What's included?
Everything you need to ship a production-grade solution.
Django Web Applications
Full-featured platforms with ORM, authentication, admin panels, and REST APIs via Django REST Framework.
FastAPI Services
Async, type-safe APIs with auto-generated OpenAPI docs — a good fit for high-throughput endpoints and ML backends.
Background Jobs & Pipelines
Celery workers, scheduled jobs, and ETL pipelines for work that should not block a web request.
ML Model APIs
Serving scikit-learn, PyTorch, or hosted LLMs as versioned, monitored REST endpoints.
Scraping & Automation
Playwright and Scrapy pipelines for data acquisition and business-process automation.
Legacy Python Modernisation
Upgrading old Python and Django versions, adding tests, and splitting monoliths where it pays off.
How does a project run?
Transparent, milestone-driven delivery from day one.
Requirements & Architecture
We map your requirements to the right framework — Django for feature-rich web apps, FastAPI for performance-critical APIs.
Database Design
PostgreSQL schema, model definitions, migration strategy, and indexing plan.
API Development
Endpoints with input validation, error handling, and generated documentation.
Testing & Security
Pytest unit and integration tests, auth and injection checks, and a dependency audit.
Deployment & Monitoring
Docker, Gunicorn, and Nginx deployment with error tracking, uptime monitoring, and backups.
Which technologies do we use?
Battle-tested tools we rely on to deliver.
How much does it cost?
MVP / Launch: from ~$3k
Typically 4–8 weeks
Standalone APIs usually fit the MVP tier; full Django platforms with integrations typically land in Product / Growth.
Typical starting points, not quotes. Final pricing depends on scope and is fixed in writing after a discovery call.

Common questions about this service.
Django or FastAPI — which should I choose?
Django suits feature-rich web platforms where you want batteries included (ORM, admin, auth). FastAPI suits high-throughput APIs, microservices, and ML backends. We recommend one based on your project, not habit.
Can you connect a Python backend to my existing React frontend?
Yes — this is one of our most common project shapes. We build the Django REST Framework or FastAPI backend and wire it to your React or React Native client.
Do you deploy machine learning models?
Yes. We deploy models behind FastAPI with input validation, caching, versioned endpoints, and monitoring, using hosted APIs or your own models.
