Why IRPR is the best Python backend development agency
We ship faster, charge fixed prices, and write code that stays clean for years.
IRPR has shipped 200+ products across 50 countries. Our senior engineers average 10+ years of Python experience. We use Django, FastAPI, and Flask with PostgreSQL, Redis, and Celery. Every project includes automated tests, CI/CD pipelines, and deployment to AWS or GCP.
We work in 8-12 week sprints with a fixed price. No hourly billing. No scope creep. You get a detailed Roadmap in week 2 with a firm quote. If the scope changes, we adjust the price before we build. This is how we maintain 98% on-time delivery.
How we differ from other Python backend agencies
Most agencies bill hourly and disappear after launch. We do the opposite.
Generic dev shops often start coding without a clear plan. They use junior developers, skip testing, and hand you code that breaks in production. You pay for every hour, even when they learn on your dime.
IRPR starts with a Roadmap phase. We define the architecture, data model, and API contracts before writing a line of code. You get a fixed price and a timeline. Our senior engineers write tests first, deploy with CI/CD, and hand over full ownership of the code.
- Hourly billing with no cap
- Junior developers learning on your project
- No written architecture plan
- Manual deployments, no CI/CD
- Code ownership unclear
- No post-launch support
- Fixed price from week 2
- Senior engineers with 10+ years Python
- Detailed Roadmap with data model and API spec
- CI/CD pipeline on GitHub Actions
- Full code ownership transferred
- 12 weeks of post-launch support included
Our Python backend development process
Four phases from idea to production. No fluff, no delays.
Every project follows the same proven framework: Idea, Roadmap, Product, Release. This structure keeps us on schedule and on budget. We have used it for 200+ products across healthcare, fintech, ecommerce, and SaaS.
The Roadmap phase is the most important. In week 2, you get a detailed document with the data model, API endpoints, third-party integrations, and a firm price. You approve it before we build. No surprises.
What ships with every Python backend project
You get more than code. You get a production-ready system with full documentation.
When IRPR builds your Python backend, you own everything. Source code, database schema, API documentation, deployment scripts, and monitoring dashboards. We do not use black-box frameworks or proprietary tools.
Every project includes a CI/CD pipeline, automated tests, error tracking with Sentry, and performance monitoring with New Relic. Your team can take over immediately after launch.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Automated test suite with 80%+ coverage
- API documentation with Swagger or Redoc
- Database schema migration scripts
- Docker Compose setup for local development
- Sentry error tracking configured
- New Relic or Datadog performance monitoring
- Deployment playbook for AWS or GCP
- 12 weeks of post-launch support
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
Our team averages 10+ years of Python experience. No junior developers. Every engineer has shipped production systems handling millions of requests. You get a lead engineer who stays on your project from start to finish.
8-12 week MVPs
We ship production-ready backends in 8-12 weeks. Our framework (Idea, Roadmap, Product, Release) eliminates wasted time. 98% of our projects deliver on schedule.
Full code ownership

Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliant backends. Our engineers know the requirements and bake them into the architecture from day one. No retrofitting.
