Expert Python Backend Development ServicesBackend Development
We build scalable Python backends for your product. Ship a production-ready API in 8-12 weeks with fixed pricing.
IRPR builds expert Python backend development services using Django, FastAPI, Flask, Celery, Redis, and PostgreSQL. We design APIs, microservices, and data pipelines that handle millions of requests with sub-200ms latency.
Every project ships with a fixed price between $80K and $250K, delivered in 8-12 weeks. We include CI/CD, automated tests, API documentation (Swagger/OpenAPI), and compliance support for HIPAA, PCI-DSS, and SOC 2.
Our buyers are CTOs at SaaS startups needing a scalable API, product managers at fintech companies requiring PCI-compliant backends, healthcare IT directors building HIPAA-compliant data systems, and ecommerce leaders who need real-time inventory and payment APIs.
Types of software we ship.
REST API Development
Build stateless RESTful APIs with Django REST Framework or FastAPI. Includes versioning, pagination, and rate limiting.
GraphQL API Development
Create flexible GraphQL endpoints using Graphene-Django or Strawberry. Enables frontend teams to query exactly what they need.
Microservices Architecture
Decompose monoliths into independent Python microservices with Docker and Kubernetes. Each service scales independently.
Data Processing Pipeline
Build ETL pipelines with Apache Airflow, Celery, and Pandas. Process terabytes of data with fault tolerance and monitoring.
Real-Time WebSocket Server
Implement low-latency WebSocket servers using FastAPI or Django Channels. Supports chat, live dashboards, and collaborative editing.
Background Job Processing
Offload heavy tasks to background workers with Celery and Redis. Handles email sending, report generation, and data sync.
Authentication & Authorization System
Implement OAuth2, JWT, and SAML-based auth with Django Allauth or Authlib. Supports role-based access control and multi-tenancy.
Serverless Python Backend
Build event-driven backends with AWS Lambda, API Gateway, and Chalice. Pay per request, auto-scale to zero.
We build for every business type.

Why expert Python backend development matters
Your backend is the foundation of your product. A poorly built one costs you users and revenue.
IRPR has delivered 200+ Python backends that handle millions of requests daily. We use Django, FastAPI, and PostgreSQL to build systems that scale from 100 to 100,000 concurrent users without rearchitecture.
Our expert Python backend development services include performance benchmarking, load testing, and horizontal scaling. We ensure 99.9% uptime with automated failover and monitoring.
How we build your Python backend
We follow a proven process that eliminates guesswork and delivers a production-ready system on time and on budget.
Every project starts with a 2-week Roadmap phase where we define architecture, API contracts, and a fixed price. We use Django or FastAPI based on your needs, and we set up CI/CD from day one.
Our team writes automated tests, API documentation, and deployment scripts alongside the code. You get a fully documented, tested, and deployed backend at the end of 8-12 weeks.

- No post-launch support
- Fixed price from week 2
- Automated CI/CD with GitHub Actions
- Comprehensive API docs (Swagger/OpenAPI)
- Horizontal scaling from day one
- Security audit and compliance checks
- 30 days post-launch support included
Our Python backend development process
We break the project into four phases so you always know what's happening and when it will ship.
Each phase ends with a deliverable you can review and approve. We use agile sprints with bi-weekly demos.
The process is designed for speed without cutting corners. 98% of our projects ship on time.
What you get when you ship with IRPR
Every project includes these deliverables by default. No hidden costs, no surprises.
You own the code from day one. We deploy to your cloud account and set up monitoring so you can sleep at night.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- Automated unit and integration tests (80%+ coverage)
- API documentation with Swagger/OpenAPI
- Error tracking with Sentry
- Application monitoring with Datadog or New Relic
- Cloud infrastructure on AWS or GCP (Infrastructure as Code)
- Security scanning with SonarQube and Snyk
- Performance benchmarks and load test report
- 30 days post-launch support with SLA
What we ship in this practice.
Real-time analytics dashboard for a SaaS platform
Built a Python backend using FastAPI and WebSockets to stream user events. Reduced data latency from 5 minutes to under 1 second, enabling real-time dashboards. Tech stack: FastAPI, Redis, PostgreSQL, WebSocket, AWS Lambda.
HIPAA-compliant patient data API for telemedicine
Developed a Django REST API with FHIR standards for a telemedicine startup. Achieved HIPAA compliance and handled 10,000+ patient records per day. Tech stack: Django, PostgreSQL, Celery, AWS HealthLake.
Payment processing microservice for fintech
Created a PCI-DSS compliant payment microservice using FastAPI and Stripe integration. Processed $2M in transactions in the first month with 99.99% uptime. Tech stack: FastAPI, Stripe, PostgreSQL, Docker, Kubernetes.
Inventory management backend for ecommerce
Built a scalable inventory API with real-time stock updates and order synchronization. Reduced inventory discrepancies by 95% and handled 500 SKUs per store. Tech stack: Django, PostgreSQL, Redis, Celery, Shopify API.
ML model serving backend for image recognition
Developed a Python backend using FastAPI and TensorFlow Serving to deploy computer vision models. Achieved 200ms inference time at 1000 requests/second. Tech stack: FastAPI, TensorFlow, Redis, AWS SageMaker, Docker.
IoT data pipeline for manufacturing
Built an event-driven pipeline using Python, Kafka, and InfluxDB to process sensor data from factory equipment. Reduced downtime by 30% through predictive alerts. Tech stack: Python, Kafka, InfluxDB, Flask, AWS IoT Core.
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 upfront.
Senior engineers only
Our team consists of senior Python developers with 10+ years average experience. No junior developers, no outsourcing middlemen. Every line of code is reviewed by a lead architect.
8-12 week MVP delivery
We ship a production-ready backend in 8-12 weeks. Our process is optimized for speed without sacrificing quality. 98% of our projects ship on time.
Full code ownership
You own the entire source code from day one. No licensing fees, no vendor lock-in. We deploy to your AWS or GCP account, and you have full access to the repository.
Built-in compliance
We have built backends for HIPAA, PCI-DSS, SOC 2, and FERPA. Our security checklist includes encryption at rest and in transit, role-based access control, and audit logging.
Post-launch support included
After deployment, we provide 30 days of post-launch support to handle any issues. We also offer ongoing maintenance at a fixed monthly rate if needed.
