Why Choose IRPR as Your Senior Python Backend Development Vendor
We deliver production-ready backends in 12 weeks with a fixed price and full ownership.
IRPR has shipped over 200 backend systems for clients in 50+ countries. Our engineers average 10 years of Python experience. We use Django, FastAPI, Celery, and PostgreSQL on every project. Every backend ships with automated tests, CI/CD pipelines, and monitoring.
We work async-first with daily overlap hours for US time zones. You get a dedicated senior engineer who writes the code, reviews it, and deploys it. No junior developers. No offshore time zones. No hourly billing.
The Difference Between IRPR and a Generic Development Shop
Most vendors sell you junior engineers at hourly rates. IRPR sells you senior engineers at a fixed price.
A typical dev shop assigns 3 junior developers to your project. They learn on your dime. You pay for their mistakes. Deadlines slip. Code quality drops. You end up rewriting the backend 6 months later.
IRPR assigns one senior engineer who owns the entire backend. You get production code in 12 weeks. No rewrites. No surprises. The code is yours from day one.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No compliance expertise
- Code that needs rewriting
- No CI/CD or monitoring
- No fixed timeline
- Senior engineers with 8+ years Python experience
- Fixed price from week 2
- HIPAA, PCI-DSS, SOC 2 built in
- Production code on day 1
- CI/CD pipeline with Sentry and Datadog
- 12-week delivery guarantee
Our Process for Building Your Python Backend
Four phases from idea to production. You stay in control at every step.
We start with a 2-week Roadmap phase where we define the architecture, data model, API endpoints, and compliance requirements. You get a fixed price and timeline before we write a single line of code.
Then we build your backend in 8-12 weeks. You see progress daily. We deploy to staging after week 3. You test and give feedback. We ship to production with everything included.
What Ships with Every Python Backend
No hidden costs. No missing pieces. Everything you need to run your backend in production.
Every backend we build includes a full test suite, CI/CD pipeline, monitoring, and documentation. You can deploy to any cloud provider. You own everything.
We also include a 30-day post-launch support period. If something breaks, we fix it within 24 hours.
- Full source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Automated test suite (unit, integration, end-to-end)
- API documentation with Swagger or OpenAPI
- Sentry error tracking and Datadog monitoring
- Dockerized development and production environments
- Database schema and migration scripts
- Deployment playbook for AWS or GCP
- Security audit report (OWASP top 10)
- 30-day post-launch support SLA
