Top Python Backend Development ServicesBackend Development
We build production-ready Python backends using Django, FastAPI, and PostgreSQL. Over 200 products shipped to 50+ countries, your API gets the same treatment.
IRPR engineers build high-performance Python backends for web and mobile applications. We use Django for rapid, feature-rich systems and FastAPI for high-throughput, real-time APIs.
Projects typically ship in 8-12 weeks with prices from $80K to $250K. We handle compliance standards like HIPAA, PCI-DSS, and SOC 2 during development, not after.
Who hires us: startup CTOs needing a scalable MVP, engineering managers replatforming a legacy monolith, and product leaders launching a data-intensive SaaS.
Types of software we ship.
REST API Development
Build robust REST APIs with Django REST Framework or FastAPI. Supports OAuth2, rate limiting, and versioning out of the box.

Why choose IRPR for Python backend development?
Our track record with Python backends speaks for itself.
Every Python backend we ship goes through the same rigorous process: senior engineers architect the system, write comprehensive tests, and deploy with CI/CD. We have built over 200 backends for startups and enterprises across 50 countries.
Our fixed-price roadmap phase (week 2) eliminates budget uncertainty. You get a complete specification, tech stack decision, and exact timeline before a single line of code is written.
The difference between generic shops and IRPR
Not all Python developers are equal. Here is what separates IRPR from the rest.
Many agencies bill by the hour, change scope constantly, and deliver unfinished code with no documentation. You end up with an unmaintainable backend that costs more and ships late.
IRPR takes a different approach. We fix the price up front, assign senior engineers only, and deliver a fully documented, deployed backend in under 12 weeks.
- No defined process
- Hourly billing with unexpected overruns
- Unclear code ownership
- Low code quality and missing tests
- No compliance knowledge
- Vague timelines that slip
- Fixed price from roadmap phase
- Senior engineers only (10+ years Python)
- Full code ownership from day one
- CI/CD pipeline, tests, documentation
- Built-in HIPAA, PCI-DSS, SOC 2 compliance
- 8-12 week guaranteed timeline
Our Python backend development process
We move from idea to production in four clear phases.
Each phase is designed to reduce risk and keep you informed. You see working software every week.
What ships with your Python backend
Every project includes these deliverables by default.
No hidden costs or missing pieces. Everything you need to run, maintain, and extend your backend is included.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions
- API documentation (OpenAPI / Swagger)
- Unit and integration tests (pytest, 80%+ coverage)
- Performance benchmark report
- Deployment guide and runbook
- Architecture diagram
- Logging and monitoring (Sentry, Datadog)
- Docker containers for local development
- Staging environment with sample data
What we ship in this practice.
