Leading Python Backend Development DevelopersBackend Development
We build production-grade Python backends for web apps, APIs, and data pipelines. 200+ products shipped, 8-12 week MVPs, fixed pricing.
IRPR is a software development studio that builds Python backends for web apps, mobile apps, and data-intensive platforms. We use Django, FastAPI, Flask, Celery, Redis, PostgreSQL, and AWS Lambda to ship production-ready systems.
Every project starts with a 2-week Roadmap phase where we define the architecture, data model, and API contracts. MVPs ship in 8-12 weeks with fixed pricing from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA.
We work with CTOs who need a scalable backend for their SaaS product, founders launching a marketplace or fintech platform, engineering leads who want to offload backend development to a senior team, and product managers who need a reliable API for their mobile app.

Why leading python backend development developers choose IRPR
We have shipped 200+ Python backends for companies in 50+ countries.
Our team of senior Python engineers has built backends for SaaS platforms handling 1 million+ daily requests, fintech systems processing $50M+ in transactions, and healthcare platforms managing 100K+ patient records. Every project uses Django, FastAPI, or Flask with PostgreSQL, Redis, and AWS.
We follow a fixed-price model with no hourly billing. The Roadmap phase (week 2) produces a detailed architecture document, data model, and API contracts. After that, we build the MVP in 8-12 weeks with weekly demos and full code ownership.
How IRPR differs from other python backend development agencies
Most agencies bill hourly and deliver incomplete code. We do the opposite.
Generic dev shops often start coding without a clear architecture. They use junior developers, change requirements mid-project, and hand over code with no tests or documentation. You end up with a fragile backend that costs more to maintain than to build.
IRPR assigns senior engineers only. We start with a 2-week Roadmap that defines every endpoint, data model, and integration. We write tests, set up CI/CD, and deploy to AWS or your own infrastructure. You get full ownership of the code and a 30-day warranty.
- Hourly billing with no cap
- Junior developers on your project
- No architecture document
- No automated tests
- No CI/CD pipeline
- Code ownership unclear
- Fixed price from $80K to $250K
- Senior engineers only (8+ years experience)
- 2-week Roadmap with full architecture
- 90%+ test coverage
- CI/CD on GitHub Actions
- Full code ownership from day one
Our process for building your python backend
We follow a 4-phase process that guarantees on-time delivery.
Every project starts with a discovery call where we understand your product, users, and technical requirements. We then move into the Roadmap phase where we produce a detailed plan.
The build phase uses 2-week sprints with weekly demos. We deploy to staging after each sprint and to production after the final sprint. The release phase includes documentation, training, and a 30-day warranty.
What ships with every python backend project
You get more than just code. Every project includes these deliverables.
We believe in shipping production-ready systems, not prototypes. Every backend we build comes with automated tests, CI/CD pipelines, monitoring, and documentation.
You own everything from day one. There are no licensing fees, no ongoing royalties, and no vendor lock-in. You can deploy the code anywhere.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Automated tests with 90%+ coverage
- API documentation with Swagger or Redoc
- Docker containers for local development
- Deployment scripts for AWS, GCP, or Azure
- Sentry error tracking and Datadog monitoring
- Database migrations and seed data
- Security audit report (OWASP top 10)
- 30-day warranty with bug fixes
What we ship in this practice.
SaaS analytics platform backend

Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Senior engineers only
Our team averages 10+ years of Python experience. No junior developers, no offshore teams, no code monkeys. Every engineer has shipped production systems at scale.
Full code ownership
You own every line of code from day one. No licensing fees, no royalties, no vendor lock-in. Deploy to your own AWS, GCP, or Azure account.
8-12 week MVPs
We ship production-ready backends in 8-12 weeks. Not a prototype, not a demo, but a fully tested, deployed system with CI/CD and monitoring.
