Expert Python app development firm with proven results
We have shipped over 200 Python applications for clients in 50 countries.
IRPR's track record speaks for itself. Our Python apps handle 10,000 requests per second, process terabytes of data, and serve users across healthcare, fintech, and e-commerce. Every project includes automated testing, CI/CD pipelines, and 99.9% uptime SLAs.
We use Python 3.12, Django 5, FastAPI 0.110, and Postgres 16. All code goes into your repository on day one. No black boxes, no vendor lock-in.
Why IRPR is different from other Python firms
Most agencies promise Python expertise but deliver junior developers and hourly billing.
Generic dev shops assign a mix of junior and mid-level developers, bill by the hour, and deliver two months late. They rarely understand compliance like HIPAA or PCI-DSS. Their code often lacks automated tests and proper documentation.
IRPR works differently. You get a fixed price quote during the Roadmap phase (week 2) with no surprises. Every engineer is senior level (7+ years experience) with deep Python knowledge. We handle compliance, deploy on AWS/GCP, and provide 30 days of post-launch support.
- Junior developers assigned to your project
- Hourly billing with no cap
- No fixed timeline estimate
- Does not handle HIPAA or PCI-DSS compliance
- Code owned by the agency until final payment
- Limited automated testing
- Senior Python engineers only (7+ years experience)
- Fixed price quoted in Roadmap (week 2)
- 8-12 week delivery with milestones
- HIPAA, PCI-DSS, SOC 2 compliance out of the box
- Full code ownership from day one
- CI/CD with 80%+ test coverage
Our process for building your Python app
We follow a four-phase approach to ship your Python application on time and on budget.
Every engagement starts with a Discovery phase where we map your requirements, user flows, and data model. Then we create a detailed Roadmap with a fixed price and timeline. Development runs in 2-week sprints with regular demos. Finally, we deploy to production and provide 30 days of support.
The Discovery and Roadmap phases take 2 weeks. Development for a typical MVP takes 6-10 weeks. Deployment and handoff take 1 week.
What ships with every Python app project
Every deliverable includes everything you need to run and maintain the application independently.
When we finish your Python project, you receive the complete source code, infrastructure-as-code, and all documentation. There is no proprietary framework or hidden dependency.
Your team can take over immediately with our handover training. We also offer optional post-launch maintenance at a fixed monthly rate.
- Complete source code in your private GitHub repository
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error tracking and Datadog monitoring configured
- Docker containerization with docker-compose for local development
- Infrastructure-as-code (Terraform or Pulumi) for AWS/GCP
- API documentation auto-generated with Swagger/OpenAPI
- Database schema migration scripts (Alembic or Django migrations)
- Deployment runbook and architecture diagrams
- HIPAA/PCI-DSS compliance documentation (if applicable)
- 30-day post-launch support with SLA

Why teams hire us.
Senior Python engineers only
Every developer on your project has 7+ years of Python experience. No junior contractors, no overseas outsourcing. Our team averages 10 years of production Python.
Fixed price, not hourly
We quote a fixed price during the Roadmap phase (week 2). You never see an hourly bill. If scope changes, we adjust the fixed price together upfront.
8-12 week MVP delivery
Most projects ship a production-ready MVP in 8 to 12 weeks. We have a 98% on-time delivery rate across 200+ projects.
HIPAA, PCI-DSS, SOC 2 certified
We build compliant Python apps for healthcare, fintech, and enterprise. Our team includes engineers who have passed HIPAA audits for major hospital systems and PCI-DSS assessments for payment processors.
Full code ownership from day one
You own all source code from the first commit. We push to your private GitHub repository. No proprietary frameworks, no licensing fees, no lock-in.
30-day post-launch support included
After release, we stay on for 30 days to fix bugs, train your team, and ensure smooth operation. We respond within 4 hours during business days.
Idea → Roadmap → Product → Release.
