Why choose a leading Python backend development company
Our track record speaks in numbers.
IRPR has shipped over 200 production backends across 50 countries. Every project is built by senior Python engineers with an average of 12 years of experience.
We deliver 98% of projects on time and maintain 99.9% uptime after launch. Our fixed-price model removes budget surprises.
The difference with IRPR
Generic dev shops vs a true Python backend partner.
Most agencies rely on junior developers and vague timelines. You end up with code you cannot maintain and a process that never ends.
IRPR assigns senior engineers from day one and fixes your price after the Roadmap phase. You own every line of code.
- Uses junior developers
- No fixed timeline
- No ownership of code
- Uses outdated frameworks
- No CI/CD setup
- No post-launch support
- Senior Python engineers with 10+ years
- Fixed 8-12 week roadmap
- You own all source code
- Modern stack: FastAPI, Django, Pydantic
- Automated CI/CD and monitoring
- Dedicated support after launch
Our process for Python backend delivery
Four phases from idea to production.
We follow a structured approach that removes guesswork. Each phase has clear deliverables and milestones.
Clients see progress every two weeks and can adjust priorities along the way.
What ships with every Python backend project
Every deliverable is built into our process.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- PostgreSQL database schema and migrations
- REST API with OpenAPI docs
- Sentry error tracking
- Docker containerization
- Load testing results
- Deployment playbook
- Admin dashboard (if applicable)
- 12-month warranty on bugs
What we ship in this practice.
Payment Processing API for Fintech Startup
Built a FastAPI-based payment gateway that processes 5,000 transactions per day with 99.99% uptime. Used Stripe Connect, PostgreSQL, Redis.
Real-Time Analytics Backend for SaaS
Developed a WebSocket server using Django Channels that streams live user data to dashboards. Reduced data latency from 10 seconds to under 100ms.
HIPAA-Compliant Patient Data API
Created a Django backend with FHIR integration for a telehealth platform. Passed HIPAA audit on first attempt.
Order Management System for Ecommerce
Built a microservices backend handling 50,000 SKU updates per hour. Used Celery for async processing and PostgreSQL for inventory.
ML Model Serving API for Data Company
Deployed a FastAPI service that serves TensorFlow models with under 50ms latency. Handles 10,000 predictions per second.
Real Estate MLS Integration Backend
Created an API layer that syncs MLS data from 5 sources into a single PostgreSQL database. Reduced data merge time by 80%.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices.
Senior engineers only
Our team averages 12 years of Python experience. We skip junior developers entirely.
You own the code
All source code, documentation, and IP belong to you from day one. No lock-in, no licensing.
8-12 week MVPs
We ship production-ready backends in 8-12 weeks. Over 200 products delivered on time.
Built for compliance
Our systems are designed for SOC 2, HIPAA, PCI-DSS, and GDPR from the start. We don't bolt on security.
Post-launch support
Every project includes a 12-month warranty on bugs and critical issues. We don't disappear after deployment.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
