Senior Python Backend Development PartnerBackend Development
Build scalable Python backends with senior engineers. We ship production-ready APIs in 12 weeks with fixed pricing.
IRPR builds production Python backends using Django, FastAPI, and PostgreSQL. We handle API design, data modeling, authentication, and cloud deployment with AWS or GCP.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance as part of the build.
CTOs hire us to replace stalled offshore teams. Startup founders hire us to build their first production backend. Product managers hire us to add real-time features or third-party integrations.

Why You Need a Senior Python Backend Development Partner
A senior partner means fewer rewrites, faster shipping, and production-ready code from day one.
IRPR assigns 2-3 senior Python engineers per project. Each engineer has 8+ years of Django or FastAPI experience. You skip the junior learning curve and get code that handles 10K requests per second on day one.
We build with CI/CD pipelines, automated tests, and monitoring from the start. Every backend ships with Sentry error tracking, Datadog performance monitoring, and PagerDuty alerts. No tech debt. No surprises.
The Difference Between a Dev Shop and a Senior Python Backend Partner
Most dev shops assign junior devs to senior roles. IRPR gives you senior engineers who own the outcome.
Generic dev shops bill hourly and push scope creep. They use outdated frameworks and skip testing. You get a backend that breaks in production and a team that disappears after launch.
IRPR works on fixed price with a clear Roadmap phase. We use Django 5, FastAPI 0.110, and PostgreSQL 16. Every backend ships with 90% test coverage, CI/CD, and a 30-day warranty.

How We Build Your Python Backend in 12 Weeks
Every project follows a repeatable 4-phase process. You stay in control at every step.
We start with a 2-week Roadmap phase. You pay a fixed fee for a detailed spec, architecture diagram, and data model. If you approve, we move to Product phase with the same scope and price. No surprises.
Each phase ends with a demo. You test the API in staging before we deploy to production. We use GitHub Actions for CI/CD and Terraform for infrastructure. Your team can take over anytime.
What Ships with Every Python Backend
Every backend includes production essentials. No hidden costs, no missing pieces.
You own the full source code, infrastructure as code, and all documentation. We set up monitoring and alerts so you know when something breaks before your users do.
All backends ship with automated tests, CI/CD pipelines, and a staging environment. You get a 30-day warranty where we fix any bugs at no cost.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- PostgreSQL database schema with migrations
- REST or GraphQL API with auto-generated docs (Swagger/GraphiQL)
- Authentication and authorization (JWT, OAuth 2.0, or session-based)
- Sentry error tracking and Datadog performance monitoring
- Docker containers and Terraform infrastructure scripts
- 90% test coverage with pytest
- Staging and production environments on AWS or GCP
- 30-day warranty with SLA for critical bugs

Why teams hire us.
Senior engineers only, no juniors
Every IRPR engineer has 8+ years of Python experience. You never pay for ramp-up time or get code you have to rewrite. Our team has built backends for companies like Stripe, Airbnb, and Dropbox.
Fixed price, not hourly
You get a fixed price in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. If we add scope, we quote it separately with your approval.
Production-ready from day one
All backends ship with CI/CD, monitoring, automated tests, and infrastructure as code. You get a staging environment and a 30-day warranty. Your team can take over immediately.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliance into the architecture. No bolt-on security. Our backends pass audits without rework. We have shipped 40+ HIPAA-compliant backends.
12-week average delivery
Most backends ship in 8-12 weeks from kickoff to production. We use Django and FastAPI to move fast without cutting corners. Our record is 6 weeks for a payment API.
Full code ownership
You own the source code, infrastructure scripts, and documentation. No licensing fees, no vendor lock-in. You can deploy anywhere or bring your own team after launch.
