Leading Python Backend Development FirmBackend Development
We build Python backends that handle millions of requests per day. Senior engineers, fixed pricing, 8-12 week delivery.
IRPR is a leading python backend development firm. We build production-grade backends using Django, FastAPI, Flask, and async Python frameworks. Our teams deploy on AWS, GCP, or Azure with CI/CD pipelines and automated testing.
Every project ships in 8-12 weeks with a fixed price. Typical backend projects range from $80K to $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA out of the box.
CTOs hire us to replace unstable legacy backends. Startup founders hire us to build their first production API. Product managers hire us to add real-time features or third-party integrations. Enterprise architects hire us to design scalable microservices.
Types of software we ship.
REST API backend

Why IRPR is the leading python backend development firm
We deliver production-ready Python backends that scale from day one.
Every backend we build starts with a two-week Roadmap phase. Our senior engineers map out the data model, API contracts, and infrastructure before writing a single line of code. This eliminates rework and keeps projects on a fixed timeline.
We use Django for data-heavy backends and FastAPI for high-throughput APIs. All code is deployed on AWS ECS or GCP Cloud Run with automated CI/CD via GitHub Actions. Every API gets Sentry error monitoring and Datadog performance tracking from the first deployment.
What sets IRPR apart from other Python agencies
Most Python shops bill hourly and change scope. We do the opposite.
Generic dev shops start coding without a clear plan. They charge by the hour, add scope mid-project, and hand over code with no documentation. You never know the final cost or timeline.
IRPR gives you a fixed price after a two-week Roadmap. We write tests, document APIs, and deploy to production. You own the source code, the CI/CD pipeline, and the infrastructure from day one.
- Hourly billing with no cap
- Scope creep on every sprint
- Junior developers on your project
- No automated tests or CI/CD
- No documentation or API specs
- You don't own the full codebase
- Fixed price after Roadmap phase
- Strict scope control with change orders
- Senior engineers only (8+ years)
- 100% test coverage, CI/CD on day one
- Auto-generated API docs (OpenAPI)
- Full source code ownership
How we build your Python backend in 8-12 weeks
Our process removes guesswork. Every phase has a clear deliverable.
We follow a four-phase process: Idea, Roadmap, Product, Release. Each phase ends with a review and a sign-off. You see progress every week, not just at the end.
The Roadmap phase locks in the data model, API endpoints, and infrastructure decisions. The Product phase builds the backend in two-week sprints. The Release phase handles load testing, security review, and production deployment.
What ships when you hire IRPR
Every project includes these deliverables by default. No extra fees.
When you hire the leading python backend development firm, you get more than code. You get a complete production system with monitoring, documentation, and infrastructure as code.
Our team sets up everything needed to run the backend in production. You don't need to hire a DevOps engineer or a QA team separately. It's all included in the fixed price.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Dockerized application with docker-compose
- PostgreSQL database with migration scripts
- API documentation via Swagger/OpenAPI
- Sentry error tracking and alerts
- Datadog performance monitoring dashboards
- Load test results with k6 or Locust
- Security audit report (OWASP top 10)
- One-month post-launch warranty

Why teams hire us.
Senior engineers only, no juniors
Every engineer on your project has 8+ years of Python experience. We don't staff juniors or offshore teams. You talk directly to the engineers building your backend.
Fixed price, not hourly billing
We quote a fixed price after the two-week Roadmap phase. No hourly rates, no surprise invoices, no scope creep. You know the exact cost before we start building.
8-12 week delivery, not 6 months
Most agencies take 6-9 months for a production backend. We ship in 8-12 weeks because we plan first and build second. Every sprint ends with a deployable backend.
Full code ownership from day one
You own every line of code we write. No licensing fees, no lock-in, no recurring royalties. The source code, infrastructure scripts, and documentation are all yours.
Built-in compliance for regulated industries
We have built backends for HIPAA, PCI-DSS, SOC 2, and FERPA. Our engineers know the compliance requirements and bake them into the architecture from the start.
Production monitoring and support included
Every backend ships with Sentry error tracking, Datadog performance monitoring, and automated alerts. We provide one month of post-launch support at no extra cost.
Idea → Roadmap → Product → Release.
