Why choose IRPR for Python backend development
We deliver fast, secure, and scalable backends that your team can maintain.
Our senior engineers average 10+ years of Python experience. We have shipped backend systems for companies in 50 countries, from early-stage startups to Fortune 500 enterprises.
Every project follows our proven Idea-Roadmap-Product-Release framework. You get a fixed price, dedicated QA, and a 99.9% uptime SLA.
The difference between IRPR and generic development shops
Most agencies work hourly and cut corners on quality. We do the opposite.
Generic shops bill hourly, lack compliance expertise, and take 6+ months to deliver a working product. Their code is often undocumented and hard to maintain.
IRPR delivers fixed-price Python backends with full DevOps, automated testing, and compliance built in from day one. Your team gets clean code and full ownership.
- Hourly billing with no cap
- No compliance expertise
- Takes 6+ months
- No dedicated QA process
- Code ownership unclear
- Limited tech stack choices
- Fixed price from $80K
- HIPAA/PCI/SOC 2 built in
- 8-12 week delivery
- Automated CI/CD with Sentry
- Full code ownership
- Python specialists only
Our Python backend development process
From idea to production in 12 weeks, no detours.
We start with a 2-week Roadmap phase to define scope, architecture, and a fixed price. After that we work in 2-week sprints with weekly demos.
By week 12 you have a production-ready backend deployed on AWS or GCP, with monitoring and error tracking already in place.
What you get with every Python backend project
Everything you need to launch and scale, no hidden fees.
Every delivery includes full source code, infrastructure config, and documentation. You can hand the project to your internal team or another agency with zero friction.
- Source code in your GitHub repository
- CI/CD pipeline on GitHub Actions
- Dockerized containers with Docker Compose
- PostgreSQL schema design and migrations (Alembic)
- API documentation (OpenAPI/Swagger)
- Sentry error tracking and performance monitoring
- Cloud deployment on AWS or GCP (Terraform)
- Unit tests with 90%+ code coverage
- Database migrations (Alembic)
- Performance benchmarks with Locust
