Why choose a premium Python backend development agency
A premium agency delivers more than code. You get architecture, compliance, and a team that ships on time.
IRPR has shipped 200+ Python backends across 50+ countries. Every project starts with a 2-week Roadmap phase where we define the schema, API contracts, and test plan. You get a fixed price quote before any development begins.
Our senior engineers use FastAPI for performance, PostgreSQL for reliability, and Docker for portability. We ship with automated CI/CD pipelines on GitHub Actions, Sentry error monitoring, and Datadog performance dashboards.
How IRPR differs from generic Python development shops
Most agencies charge by the hour and change scope. IRPR gives fixed price, senior engineers, and a clear roadmap.
We start with a paid Roadmap phase. In 2 weeks, we define the data model, API endpoints, and deployment plan. You get a fixed price quote. No hourly billing, no surprise invoices.
Every backend ships with test coverage above 80%, CI/CD pipelines, and monitoring. Our senior engineers have 12+ years average experience and have worked at companies like Google and AWS.
- Hourly billing with no cap
- Junior/mid-level developers
- No compliance planning
- No CI/CD or monitoring setup
- Code ownership unclear
- No fixed timeline
- Fixed price per project
- Senior engineers only (12+ yrs avg)
- Built-in HIPAA/PCI/SOC 2 compliance
- CI/CD, Sentry, Datadog by default
- You own 100% of the code
- 8-12 week delivery
Our Python backend development process
We follow a 4-phase process from idea to production. Every phase has a clear deliverable.
The Roadmap phase takes 2 weeks and costs $5K-$10K. You get a data model diagram, API contract, and deployment plan. If you proceed, the Roadmap cost is deducted from the project fee.
After Roadmap, we build the MVP in 8-12 weeks. We use FastAPI or Django, PostgreSQL, Docker, and AWS. Every sprint ends with a demo. You see working software every 2 weeks.
What ships with every Python backend
Every project includes these deliverables. No extra charge.
We ship source code to your private GitHub repo on day one. You own everything. No licensing fees. No hidden costs.
Our CI/CD pipeline runs on GitHub Actions. It runs tests, builds Docker images, and deploys to AWS ECS. Every commit is deployable.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Docker containers for every service
- Sentry error monitoring
- Datadog performance dashboards
- Test coverage above 80%
- API documentation (OpenAPI)
- PostgreSQL database schema
- Deployment scripts for AWS ECS
- Security audit report
