Premium Python Backend Development PartnerBackend Partner
We build production-grade Python backends for SaaS, fintech, and healthcare. 12-week MVP with fixed pricing.
IRPR builds premium Python backends for companies that need reliability, speed, and compliance. We use FastAPI for high-performance APIs, Django for rapid development, and PostgreSQL for data persistence. Every project starts with a 2-week Roadmap phase to define scope and architecture.
We ship production-ready backends in 12-14 weeks with fixed pricing from $80K to $250K. Our team handles everything from API design and database modeling to CI/CD pipelines and cloud deployment on AWS or GCP. We also handle compliance for HIPAA, PCI-DSS, and SOC 2.
CTOs hire us when their in-house team is overloaded and they need a senior backend team fast. Startup founders hire us to build their MVP and get to market in 12 weeks. Enterprise engineering managers hire us to build microservices or migrate legacy Python monoliths to modern architectures.

Why a premium Python backend development partner matters
A production backend is the difference between a prototype and a business you can scale.
IRPR has shipped 200+ Python backends for companies in 50+ countries. We use FastAPI for async APIs that handle 10,000+ requests per second. Our Django backends support 1M+ users with proper caching, database indexing, and horizontal scaling.
We write 100% test coverage with pytest, enforce type hints with mypy, and run every pull request through a CI/CD pipeline with GitHub Actions. Every project includes Sentry error tracking and Datadog monitoring from day one.
Generic dev shop vs IRPR: the difference in Python backend delivery
Not all Python shops are equal. Here is what separates IRPR from a generic agency.
Generic dev shops often deliver Python backends that are slow, hard to maintain, and lack proper testing. They use hourly billing that encourages scope creep and long timelines. Their junior developers write spaghetti code that your team will have to rewrite.
IRPR delivers production-grade Python backends with fixed pricing, senior engineers only, and a 2-week Roadmap phase that locks scope. We ship testable, documented, and deployable code every time.
- Hourly billing with no price cap
- Junior developers with 2 years experience
- No test coverage or CI/CD
- 6+ month delivery timelines
- No compliance knowledge (HIPAA, PCI)
- You own nothing until final payment
- Fixed price agreed in Roadmap phase (week 2)
- Senior engineers only (8+ years experience)
- 100% test coverage with pytest and GitHub Actions
- 12-week average MVP timeline
- HIPAA, PCI-DSS, and SOC 2 ready
- You own the code from day one, full source code delivered
Our Python backend development process
We follow a 4-phase process that removes uncertainty and delivers a working product in 12 weeks.
Phase 1: Roadmap. In 2 weeks we define the architecture, data model, API endpoints, and deployment plan. You get a fixed price quote and a detailed roadmap document.
Phase 2: Build. We develop the backend in 8-10 weeks using FastAPI or Django, with daily commits, weekly demos, and continuous deployment to a staging environment.
What ships with every Python backend project
Every project comes with a standard set of deliverables that guarantee a production-ready system.
We do not just ship code. We ship a complete backend system with monitoring, documentation, and deployment scripts. Your team can take over immediately or we can keep building.
- Full source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated tests and deployment
- 100% test coverage with pytest and mypy type checking
- API documentation via OpenAPI/Swagger (FastAPI auto-generates)
- Database schema and migration scripts using Alembic
- Docker Compose setup for local development
- Production deployment on AWS ECS or GCP Cloud Run
- Sentry error tracking and Datadog performance monitoring
- Postman collection with all API endpoints
- Architecture diagram and README documentation
What we ship in this practice.

Why teams hire us.
Senior engineers only
Every engineer on your project has 8+ years of Python experience. No juniors, no offshore teams. We work in US time zones with daily overlap.
Fixed price from week 2
After the 2-week Roadmap phase, you get a fixed price quote. No hourly billing, no surprise invoices, no scope creep charges. The price is the price.
