Best Python App Development Services by the Numbers
Our track record shows what we deliver.
IRPR has shipped over 200 Python apps to clients in 50+ countries. Our average MVP timeline is 12 weeks, and 98% of projects deliver on schedule.
We maintain 99.9% uptime across all production deployments. Our clients include healthcare companies needing HIPAA compliance and fintech firms requiring PCI-DSS.
How IRPR Delivers Better Python App Development
Most agencies overpromise and underdeliver. We do the opposite.
Generic dev shops start coding before they understand your problem. They use hourly billing, which rewards slow work.
IRPR starts with a 2-week Roadmap phase where we define architecture, data models, and API contracts. You get a fixed price before any code is written.
- Hourly billing with no cap
- No upfront architecture review
- Generic Django boilerplate
- No compliance checks
- No CI/CD pipeline
- You own nothing until final payment
- Fixed price from the start
- 2-week Roadmap with full architecture
- Custom Django, FastAPI, or Flask code
- HIPAA, PCI-DSS, SOC 2 built in
- CI/CD on GitHub Actions day one
- Full source code ownership from day one
Our 4-Phase Python App Development Process
Every project follows the same proven framework.
We use the Idea - Roadmap - Product - Release framework. Each phase has clear deliverables and a fixed timeline.
The Roadmap phase is a 2-week engagement where we produce a detailed technical specification and a fixed price quote. No surprises.
What Ships with Every Python App
You get more than just code.
Every project includes production infrastructure, monitoring, and documentation. No hidden setup fees or post-launch surprises.
Our checklist ensures your team can take over immediately after launch. We provide training sessions for your developers.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Dockerized development environment
- PostgreSQL or MongoDB database with migrations
- REST API with OpenAPI documentation
- Unit tests with 80%+ coverage
- Sentry error tracking and logging
- Deployment to AWS or GCP
- Admin dashboard (Django Admin or custom)
- 30-day post-launch warranty

We ship working software in 8-12 weeks. Your first users can start testing by week 10. No 6-month development cycles.
Compliance built in
We handle HIPAA, PCI-DSS, SOC 2, and FERPA compliance as part of the build. No separate compliance audit needed after launch.
Full code ownership
You own all source code from day one. No licensing fees, no IP disputes, no vendor lock-in. Your team can take over anytime.
Post-launch support
Every project includes 30 days of warranty support. We also offer ongoing maintenance at a fixed monthly rate starting at $5K/month.
Idea → Roadmap → Product → Release.
