Expert Python Backend Development DevelopersBackend Development
We build production-grade Python backends for SaaS, fintech, and healthcare. Ship in 8-12 weeks with fixed pricing.
IRPR builds expert Python backend development for companies that need reliable, scalable APIs, microservices, and data pipelines. We use Django, FastAPI, PostgreSQL, Redis, Celery, and Docker to ship backends that handle millions of requests per day.
Every project ships with a fixed price determined during the Roadmap phase (week 2), a 8-12 week timeline, and pricing from $80K to $250K. We build to compliance standards including SOC 2, HIPAA, and PCI-DSS.
CTOs scaling a SaaS platform hire us to build subscription management and billing APIs. Fintech founders need PCI-DSS compliant payment processing. Healthcare startups require HIPAA-compliant data backends. Ecommerce platforms hire us for high-throughput order processing systems.
Types of software we ship.
REST API Development
Build RESTful APIs with Django REST Framework or FastAPI. Includes pagination, filtering, authentication via JWT or OAuth2.
GraphQL API Development
Implement GraphQL endpoints with Graphene or Strawberry. Supports real-time subscriptions and efficient data fetching.
Microservices Architecture
Design and deploy microservices using Docker and Kubernetes. Each service runs independently with its own database and API.
Real-time Data Processing
Build real-time systems with WebSockets, Redis Pub/Sub, or Apache Kafka. Used for live dashboards and chat applications.
ETL Pipeline Development
Create ETL pipelines with Python, Airflow, and dbt. Extract data from APIs, transform with Pandas, load into data warehouses.
AI/ML Model Serving Backend
Deploy machine learning models as APIs with FastAPI and TensorFlow Serving. Includes model versioning and A/B testing.
WebSocket Server Development
Build scalable WebSocket servers using Django Channels or FastAPI WebSockets. Handles 10,000+ concurrent connections.
Background Job Processing
Implement background tasks with Celery and Redis. Used for email sending, report generation, and data syncing.
We build for every business type.
SaaS
Fintech
Healthcare

Data and Analytics
Why expert Python backend development matters
Python powers the world's most demanding backends, from Instagram to Spotify.
Python is the most popular language for backend development according to the 2023 Stack Overflow survey. It offers mature frameworks like Django and FastAPI that handle everything from authentication to database migrations out of the box.
IRPR has shipped over 200 Python backends for clients in 50 countries. Our backends consistently achieve 99.9% uptime and process millions of transactions per day. We use async Python (asyncio) for high concurrency and PostgreSQL for ACID compliance.
Generic dev shop vs IRPR
Not all Python backend developers deliver the same quality. Here is the difference.
Most dev shops bill by the hour and use junior developers. They have no fixed timeline and no compliance expertise. You end up with code you do not own and a project that drags on.
IRPR works differently. We assign senior engineers only, give you a fixed price after the Roadmap phase, and deliver in 8-12 weeks. You own all code from day one, and we build compliance into every layer.
- Hourly billing with no cap
- No fixed timeline or scope
- Junior developers with 1-2 years experience
- You do not own the code
- No compliance knowledge (HIPAA, PCI-DSS)
- No post-launch support
- Fixed price from Roadmap phase
- 8-12 week delivery guarantee
- Senior engineers with 8+ years experience
- Full code ownership in your repo
- HIPAA, PCI-DSS, SOC 2 built-in
- 12 months of post-launch support
How we build your Python backend
A proven 4-phase process that de-risks your project.
Every project follows the same structure: Idea, Roadmap, Product, Release. This ensures we align on requirements before writing a single line of code, and you see working software every two weeks.
What ships with your Python backend
Every project includes these deliverables as standard.
You get more than just code. Every backend ships with a full DevOps setup, documentation, and monitoring stack. No hidden extras.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Docker containers for dev and production
- API documentation with Swagger/OpenAPI
- Unit and integration tests with pytest
- Sentry error monitoring
- New Relic performance monitoring
- Deployed on AWS/GCP/Azure with Terraform
- Post-launch maintenance for 12 months
What we ship in this practice.
Real-time fraud detection API
Built a FastAPI service that processes 500 transactions per second with sub-50ms latency. Integrated with Stripe and Plaid. Reduced fraud losses by 60% for a fintech startup.
Ecommerce checkout service
Developed a Django-based checkout system handling 10,000 concurrent users. Integrated with Shopify and Stripe. Increased checkout completion rate by 25%.
Telemedicine video backend
Built a HIPAA-compliant backend using Django Channels and WebRTC. Supports 500 concurrent video sessions. Reduced patient wait times by 40%.
SaaS subscription management API
Created a Django REST API for managing 50,000 subscribers. Integrated with Stripe Billing and SendGrid. Automated 90% of billing operations.
Data pipeline for analytics platform
Designed an ETL pipeline with Airflow and dbt that ingests 10 million events per day. Loads into Snowflake. Reduced report generation time from 4 hours to 15 minutes.
AI model serving endpoint
Deployed a FastAPI service serving a PyTorch NLP model with 99.9% uptime. Handles 1,000 requests per second with automatic scaling on Kubernetes.
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 total cost before we start building.
Senior engineers only
All engineers have 8+ years of Python experience. We never outsource to junior developers. Your project is built by someone who has shipped production backends for companies like Spotify and Airbnb.
Compliance built-in
We build to HIPAA, PCI-DSS, and SOC 2 standards from day one. Our backends include audit logging, encryption at rest and in transit, and role-based access control. No retrofitting later.
8-12 week delivery
We ship a working MVP in 8-12 weeks. Our process is optimized for speed without cutting corners. 98% of our projects deliver on time.
Full code ownership
You own every line of code we write. It lives in your GitHub repository from day one. No licensing fees, no vendor lock-in. You can take the code and run it anywhere.
Post-launch support included
Every project includes 12 months of post-launch support. We fix bugs, update dependencies, and help with scaling. You get a dedicated Slack channel with our team.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
