Expert Python Backend Development FirmBackend Development
We build scalable Python backends for SaaS, fintech, and healthcare. Get your MVP in 8-12 weeks with fixed pricing.
IRPR builds production-ready Python backends for web apps, APIs, and microservices. We use Django, FastAPI, Flask, PostgreSQL, Redis, and Celery to handle high traffic and complex business logic.
Every project ships with CI/CD on GitHub Actions, Sentry error tracking, and full AWS infrastructure. Typical timeline is 8-12 weeks with prices from $80K to $250K. We build to HIPAA, PCI-DSS, and SOC 2 standards.
Startup CTOs and product managers hire IRPR to launch their SaaS MVP. Enterprise teams bring us in to replace legacy systems. Fintech and healthcare companies trust us for our compliance expertise.
Types of software we ship.

Our track record with Python backends
We have built over 60 Python backends in the last 5 years.
Each project follows a fixed-scope Roadmap phase. We estimate in week 2, ship in 8-12 weeks, and deliver source code you own outright.
Our backends handle 10K+ requests per second on average. We monitor uptime at 99.9% with automated alerts.
Why generic agencies fail with Python backends
Generalist web shops often lack deep Python expertise.
They overuse Wordpress or PHP workarounds for API endpoints. They skip automated testing and deploy buggy code.
IRPR is different. Our team includes senior Python engineers with 10+ years of experience. We write automated tests from day one and build CI/CD pipelines into every project.
- Uses PHP or Ruby for backend logic
- No dedicated DevOps engineer
- Manual deployments only
- Sends code without tests
- Hourly billing with scope creep
- No compliance experience
- Pure Python stack (Django/FastAPI)
- Dedicated cloud architect on every project
- CI/CD on GitHub Actions, automatic deploys
- Unit, integration, and load tests written first
- Fixed price from Roadmap
- HIPAA, PCI-DSS, SOC 2 compliance
Our 4-step process for Python backend projects
We follow a repeatable framework from idea to release.
Every project starts with a 2-week Roadmap phase where we define scope, estimate fixed price, and agree on acceptance criteria.
Then we build in 2-week sprints with weekly demos. You see progress and can adjust priorities throughout the project.
What ships with every Python backend
No black boxes. You own everything.
We hand over source code in your private GitHub repository. You control the access and licenses.
Every project includes a complete set of DevOps and monitoring tools.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Docker containerization
- PostgreSQL database schema
- Redis cache setup
- Sentry error tracking
- DataDog or Prometheus monitoring
- API documentation (Swagger/OpenAPI)
- Load testing report (k6 or Locust)
- Architecture diagram and deployment guide
What we ship in this practice.
SaaS billing API
Built a Django backend with Stripe integration that handles 10,000 subscription events per day. Reduced failed payments by 40% with automatic retries. Tech: Django, Celery, Redis, Stripe.
Healthcare appointment system
FastAPI backend for a telehealth platform supporting 500 concurrent sessions. Achieved HIPAA compliance and passed security audit in week 6. Tech: FastAPI, PostgreSQL, WebSockets, Auth0.
Real-time analytics dashboard
Built a data pipeline with Apache Kafka and Python that processes 1 million events per minute. Delivered sub-100ms query times on user dashboards. Tech: Kafka, FastAPI, ClickHouse, WebSockets.
Ecommerce order management
Microservices backend for a multi-warehouse ecommerce system. Reduced order fulfillment time from 24 hours to 2 hours. Tech: Django, Celery, RabbitMQ, PostgreSQL.
Fintech transaction ledger
Built a double-entry ledger system with Django and MySQL. Handles 50,000 transactions per second with 99.99% uptime. Tech: Django, MySQL, Redis, Terraform.
EdTech assessment platform
FastAPI backend for an online exam platform serving 10,000 concurrent students. Achieved FERPA compliance and zero data breaches. Tech: FastAPI, PostgreSQL, Redis, Docker.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. Our pricing ranges from $80K to $250K for a complete backend.
Senior python engineers only
Our team has 10+ years of Python experience on average. No junior developers. Each project is staffed with a lead architect who has shipped production systems at scale.
Compliance built in
We have built backends for HIPAA, PCI-DSS, SOC 2, and FERPA environments. That means encrypted data at rest, audit logs, and access controls come standard.
CI/CD from day one
We set up GitHub Actions, Docker, and automated testing before writing the first feature. Every commit is tested and deployable. We ship with Sentry, DataDog, and load testing reports.
Source code ownership
You own the code and intellectual property fully. We deliver source code in your repository with no ongoing license fees. No vendor lock-in.
8-12 week MVP delivery
We follow a 2-week Roadmap then build in sprints. Typical MVP takes 8-12 weeks from kickoff to production release. We have shipped over 200 products on time (98% on-time rate).
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
