Experienced Python Backend Development PartnerBackend Development
We build production Python backends in 8-12 weeks. Fixed price, senior engineers, no surprises.
IRPR is an experienced Python backend development partner. We build APIs, microservices, and data pipelines using Python 3.12, FastAPI, Django, Celery, and PostgreSQL. Every project ships with automated tests, CI/CD, and monitoring.
We deliver production-ready backends in 8-12 weeks. Pricing is fixed from the Roadmap phase (week 2) and ranges from $80K to $250K depending on scope. We handle HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries.
CTOs hire us when their in-house team lacks Python depth. Startup founders hire us to ship an MVP before fundraising. Enterprise teams hire us to build internal tools or migrate legacy systems. We work async-first with daily overlap in US time zones.

Why you need an experienced Python backend development partner
A junior team or freelancer can write Python code. An experienced partner ships production systems that stay online.
IRPR has shipped 200+ Python backends across 50 countries. Our engineers average 10+ years of Python experience. We use Python 3.12, FastAPI, Django, Celery, PostgreSQL, Redis, and Docker. Every backend includes automated tests, CI/CD pipelines, and error monitoring with Sentry.
We build for scale from day one. A typical backend handles 10,000+ requests per minute with 99.9% uptime. We deploy on AWS ECS or GCP Cloud Run with auto-scaling. Our clients include a fintech processing $50M in monthly transactions and a healthcare platform serving 500,000 patients.
The difference between a freelancer and an experienced Python backend partner
Freelancers write code. IRPR ships production systems with compliance, monitoring, and documentation.
Many teams start with a freelancer and hit problems: no documentation, no tests, no deployment scripts. The code works on a laptop but breaks in production. When the freelancer leaves, no one understands the system.
IRPR builds backends that teams can maintain. Every project ships with full documentation, automated tests, CI/CD pipelines, and monitoring. We use Git for version control and deploy with Terraform. Our code is reviewed by senior engineers before it goes to production.

How we build your Python backend in 4 phases
Our process is designed to ship fast without cutting corners.
We start with a 2-week Roadmap phase. We map every endpoint, data model, and integration. You get a fixed price and a detailed timeline. No ambiguity, no surprises.
Then we build in 2-week sprints. You see working code every 14 days. We deploy to staging after each sprint. By week 8-12, you have a production-ready backend with tests, monitoring, and documentation.
What ships with every Python backend project
You get more than code. You get a production system your team can run.
Every project includes source code in your GitHub or GitLab repo, a CI/CD pipeline, automated tests, and monitoring. We also provide API documentation, deployment scripts, and a runbook for your ops team.
We use Terraform for infrastructure as code. Your backend runs on AWS ECS or GCP Cloud Run with auto-scaling. We configure Sentry for error tracking and Datadog for performance monitoring. You get alerts when something breaks.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Automated tests with pytest (90%+ coverage)
- API documentation with OpenAPI/Swagger
- Docker containers for local and production
- Terraform scripts for AWS or GCP infrastructure
- Sentry error tracking and Datadog monitoring
- Deployment runbook for your ops team
- Postman collection for API testing
- Database migration scripts with Alembic
What we ship in this practice.
Telemedicine platform backend

Why teams hire us.
Senior engineers only
Every engineer on your project has 10+ years of Python experience. We do not staff juniors. Your code is reviewed by a senior before it ships.
Fixed price, not hourly
You get a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. The price you see is the price you pay.
8-12 week delivery
We ship production backends in 8-12 weeks. Our average is 12 weeks. You see working code every 14 days in sprint reviews.
Compliance ready
We build HIPAA, PCI-DSS, and SOC 2 compliant backends. We use encryption at rest and in transit, audit logging, and role-based access control.
Full code ownership
You own all source code, documentation, and infrastructure scripts. No licensing fees, no lock-in. Your team can take over maintenance immediately.
Production monitoring included
Every backend ships with Sentry error tracking and Datadog performance monitoring. You get alerts when something breaks. We help you set up on-call rotations.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
