Why choose a leading python backend development vendor
IRPR has shipped 200+ Python backends across 50 countries with a 98% on-time delivery rate.
We use Python 3.12, FastAPI, Django, Celery, and PostgreSQL on every project. Our backends handle 10,000+ requests per second with 99.9% uptime. We deploy on AWS, GCP, or Azure using Terraform and Kubernetes.
Every backend ships with automated tests (pytest, coverage >90%), CI/CD via GitHub Actions, and monitoring via Sentry and Datadog. We also include a Postman collection and OpenAPI docs for your frontend team.
How IRPR differs from other Python backend vendors
Most agencies bill hourly and deliver late. IRPR gives you a fixed price and a firm timeline.
Generic dev shops often start coding without a clear roadmap. They use junior engineers, skip testing, and hand over code with no documentation. You pay for every hour, even when they make mistakes.
IRPR works differently. We start with a 2-week Roadmap phase where we define every endpoint, data model, and integration. You get a fixed price and a 8-12 week timeline. Senior engineers only. Full test coverage. Code ownership is yours.
- Hourly billing with no cap
- Junior engineers on your project
- No roadmap before coding
- Minimal test coverage
- No CI/CD pipeline
- Code ownership unclear
- Fixed price from the start
- Senior Python engineers only
- 2-week Roadmap phase with full spec
- pytest coverage >90%
- CI/CD via GitHub Actions
- Full code ownership
Our process for building your Python backend
We follow a 4-phase process: Idea, Roadmap, Product, Release.
Phase 1 (Idea) takes 1 week. We align on goals, user stories, and technical constraints. Phase 2 (Roadmap) takes 2 weeks. We produce a detailed spec with every API endpoint, database schema, and third-party integration.
Phase 3 (Product) takes 8-12 weeks. We build the backend in 2-week sprints with demos every Friday. Phase 4 (Release) takes 1 week. We deploy to production, set up monitoring, and hand over all code and documentation.
What ships with every Python backend
Every project includes these deliverables by default.
We don't just hand over code. You get a fully operational backend with monitoring, documentation, and deployment scripts. Your team can start using it on day one.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog performance monitoring
- OpenAPI documentation (Swagger UI)
- Postman collection for all endpoints
- Database schema migration scripts
- Docker Compose for local development
- Deployment scripts for AWS/GCP/Azure
- 1-hour walkthrough with your team
