Premium Python Backend Development DevelopersBackend Development
IRPR builds high-performance Python backends for demanding applications. Get your project shipped in 12 weeks with a fixed price.
IRPR builds premium Python backends using FastAPI, Django, and async frameworks for high-load systems. We specialize in custom APIs, microservices, and real-time data processing.
Each project ships in 12-14 weeks with a fixed price of $80K-$250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance, and deploy on AWS, GCP, or Azure.
CTOs needing to scale infrastructure, SaaS founders requiring custom APIs, and enterprises automating backend workflows hire us. Our senior engineers average 12 years of Python backend experience.
Types of software we ship.
REST API development
Build RESTful APIs with FastAPI or Django REST Framework. Includes OpenAPI docs, rate limiting, and JWT authentication.
GraphQL API development
Create flexible GraphQL backends using Strawberry or Graphene. Integrates with React, Vue, or mobile clients.
Microservices backend
Design and deploy microservices with message queues (RabbitMQ) and container orchestration (Kubernetes).
Real-time backend
Build WebSocket-based real-time backends for live chat, gaming, or IoT. Uses Redis Pub/Sub and async Python.
Data pipeline backend
Develop ETL pipelines with Apache Airflow and Apache Spark. Handles millions of records per day.
ETL backend
Extract, transform, and load data from any source into your data warehouse. Uses Snowflake, dbt, and PostgreSQL.
Serverless backend
Implement serverless backends with AWS Lambda, API Gateway, and DynamoDB. Scales automatically to zero.
Legacy backend migration
Migrate monolithic Django or Flask apps to modern async architectures. Reduces latency by 40% on average.
We build for every business type.
SaaS platforms
e-commerce
Fintech
Healthcare
Media and entertainment
Why premium Python backend development matters
A high-performance backend is the foundation of every great application.
Python backends built with FastAPI and async SQLAlchemy handle 10,000+ requests per second with sub-10ms latency. Our backends are designed for horizontal scaling from day one.
We write automated tests with pytest (80%+ coverage) and maintain full API documentation. Every deployment includes monitoring with Sentry and Datadog.
The difference between IRPR and generic development shops
Most development shops cut corners on backend architecture, leading to technical debt and poor performance.
Generic shops often underinvest in load testing and security. They may use outdated frameworks like Flask without async support, which limits scalability.
IRPR assigns a senior backend architect to every project. We use FastAPI, async SQLAlchemy, and Pydantic for type safety. Every endpoint is load-tested with Locust at 100x expected traffic.
- Hourly billing with unpredictable costs
- Junior developers with <3 years experience
- Uses Flask or Django without async
- No automated performance testing
- Manual deployment with SSH
- Code lacks documentation and typing
- Fixed price with clear milestones
- Senior Python engineers with 10+ years
- FastAPI + async SQLAlchemy + Pydantic
- Load testing with Locust up to 100k concurrent users
- CI/CD pipeline with GitHub Actions
- Full OpenAPI documentation and type annotations
How IRPR builds your premium Python backend
Our 4-phase process ensures predictable delivery and zero surprises.
Every project starts with a one-week discovery phase where we map out the architecture, data model, and API endpoints.
Development happens in 2-week sprints with demos at the end of each sprint. We deploy to staging after every sprint for real-time feedback.
What ships with your Python backend
Every project comes with a full set of artifacts that make your team independent.
You get production-ready code, not a prototype. Our delivery includes everything needed to run, debug, and extend the backend.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Docker containers for local development
- PostgreSQL database schema and migrations
- API documentation (OpenAPI 3.0)
- Unit and integration tests (pytest, 80%+ coverage)
- Load test results report
- Deployment playbook for AWS/GCP/Azure
- Sentry error tracking configured
- Postman collection for API testing
What we ship in this practice.
REST API for a SaaS analytics platform
Built a FastAPI backend with PostgreSQL and Redis caching. Reduced API response time from 500ms to 50ms and handled 50,000 daily active users. Tech stack: FastAPI, SQLAlchemy, Redis, AWS ECS.
Real-time backend for a live streaming app
Developed a WebSocket-based backend using FastAPI and Redis Pub/Sub. Supported 10,000 concurrent viewers with sub-100ms latency. Tech stack: FastAPI, Redis, WebSockets, Docker.
Microservices backend for a fintech payment system
Designed 12 microservices for payment processing, fraud detection, and ledgers. Achieved 99.95% uptime and passed PCI-DSS audit. Tech stack: FastAPI, RabbitMQ, PostgreSQL, Kubernetes.
ETL pipeline for a healthcare data platform
Built an Apache Airflow pipeline ingesting 5 million patient records monthly. Reduced data processing time from 48 hours to 2 hours. Tech stack: Airflow, Python, Snowflake, dbt.
GraphQL API for an e-commerce storefront
Created a GraphQL backend with Strawberry, integrated with Stripe and Elasticsearch. Cut product search latency by 60% and increased conversion rate by 15%. Tech stack: Strawberry, PostgreSQL, Elasticsearch, Stripe.
Serverless backend for a mobile app
Developed an AWS Lambda + DynamoDB backend for a fitness app. Scaled from 0 to 100,000 users without any infrastructure changes. Tech stack: AWS Lambda, API Gateway, DynamoDB, Cognito.
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.
Senior engineers only
Our team averages 12 years of backend experience. Every developer has shipped Python backends for companies like Netflix and Stripe.
12-week delivery guarantee
We ship your MVP in 12 weeks or less. Our record is 9 weeks for a complete payment processing backend.
Compliance-ready
We build backends that pass HIPAA, PCI-DSS, and SOC 2 audits. Each deployment includes audit logging and encryption by default.
Full code ownership
You own all source code, documentation, and IP from day one. No licensing fees, no locked-in contracts.
Post-launch support
We provide 90 days of free maintenance after launch. Includes bug fixes, monitoring, and hotfixes.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
