Professional Python Backend Development ServicesBackend Development
IRPR builds production-ready Python backends for startups and enterprises. Get a secure, scalable API in 8-12 weeks at a fixed price.
IRPR builds custom Python backends using FastAPI, Django, and Flask. We handle everything from REST APIs to background task processing with Celery and Redis.
Every project ships with a fixed price between $80K and $250K and a 8-12 week timeline. We build to compliance standards including SOC 2, HIPAA, and PCI-DSS depending on your industry.
We work with CTOs scaling their platform, startup founders needing a fast MVP, enterprise teams migrating legacy systems, and product managers adding AI features to existing products.

Why Companies Choose IRPR for Python Backend Development
Our numbers prove the results we deliver for professional Python backend projects.
IRPR has shipped over 200 products across 50 countries, with 98% delivered on time. Our Python backends run at 99.9% uptime and handle millions of requests daily.
We use a fixed pricing model that starts at $80K and covers the full build. No hourly billing means you know the cost before we write a line of code.
The Difference Between IRPR and Generic Development Shops
Not all agencies deliver the same quality for professional Python backend development.
Generic shops often charge hourly, skip architecture planning, and hand off code with no documentation. That leads to budget overruns and technical debt.
IRPR operates differently: fixed price, senior engineers, and a clear roadmap. We include post-launch support and full code ownership.
- Hourly billing, no fixed price
- No roadmap phase
- Code quality varies
- Slow to start
- No post-launch support
- Code ownership unclear
- Fixed price from $80K
- Roadmap phase in week 2
- Senior engineers only
- Starts in 1-2 weeks
- Sentry and error tracking included
- You own all code
Our Process for Professional Python Backend Development
We follow a structured four-phase approach to deliver your backend on time and on budget.
Each project starts with a two-week Roadmap phase where we define requirements, architecture, and a fixed price. No surprises.
Then we move to agile development: 8-12 weeks of building, testing, and deploying. We ship every two weeks with a running demo.
What Ships With Every Professional Python Backend Project
Every build includes a standard set of deliverables so you can run independently.
You get everything needed to own and operate the backend. No licensing fees, no hidden costs.
Our checklist covers source code, infrastructure, monitoring, and documentation. Handover is seamless.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Dockerized deployment
- API documentation (OpenAPI/Swagger)
- Unit and integration tests
- Error tracking with Sentry
- Performance monitoring with Datadog
- One year of infrastructure support
- Security audit report
- Post-launch maintenance plan
What we ship in this practice.
AI-powered Recommendation Engine for Ecommerce
Built a FastAPI backend with PostgreSQL and Redis to serve personalized product recommendations. Achieved a 15% increase in conversion rate and reduced manual merchandising by 20 hours per week.
Real-time Analytics Dashboard for SaaS
Developed a WebSocket-based backend using FastAPI and TimescaleDB that processes 10,000 events per second. Enabled live dashboards for 500+ customers with sub-second latency.
HIPAA-compliant Telemedicine API
Built a Django backend with PostgreSQL and Twilio for a telemedicine platform. Reduced patient wait times by 40% and passed HIPAA audit on first attempt.
Payment Processing Gateway for Fintech
Created a FastAPI backend integrating Stripe and Plaid for a fintech startup. Processes $5 million monthly with 99.99% uptime and PCI-DSS compliance.
Serverless Content Management for Media
Deployed a serverless Python backend on AWS Lambda with DynamoDB to serve a content platform. Scaled to 2 million monthly active users with zero maintenance overhead.
Inventory Management System for Logistics
Built a FastAPI and PostgreSQL backend with Celery for batch processing. Reduced stockouts by 80% and improved order accuracy to 99.5%.

Senior engineers only
Our team averages 10+ years of Python experience. No junior devs, no outsourcing. Every engineer has shipped production backends at scale.
8-12 week timeline
We ship production-ready backends in 8-12 weeks. With 200+ projects delivered on time, our schedule is realistic and reliable.
Full code ownership
You get all source code, Docker configurations, CI/CD pipelines, and documentation. No lock-in, no licensing fees.
Post-launch support
We include 90 days of bug fixes, performance monitoring, and infrastructure support. Extended maintenance plans available at $5K-$15K per month.
Compliance built-in
