Professional Python Backend Development ConsultantsPython Backend
Your Python backend ships in 8-12 weeks with fixed pricing from $80K to $250K. No scope creep no hourly billing.
IRPR is a studio of senior engineers who specialize in professional Python backend development. We build REST APIs, real-time WebSocket services, and data pipelines using Django, FastAPI, Celery, and PostgreSQL.
Every project starts with a paid Roadmap phase (week 2) where we define the full scope and deliver a fixed quote. Typical MVPs take 8 to 12 weeks and cost between $80,000 and $250,000. We maintain HIPAA, PCI-DSS, and SOC 2 compliance.
Our clients include CTOs at funded startups who need a production-ready Python backend before the next funding round. Product managers at mid-market companies migrating off a monolith to microservices. And tech leads at agencies who need a reliable senior team to white-label.
Types of software we ship.
REST API development
Stateless JSON APIs with Django REST framework or FastAPI. Supports OAuth2, rate limiting, and OpenAPI docs.
GraphQL backend
Strawberry or Graphene-based GraphQL endpoints with resolvers, subscriptions, and query optimization via DataLoader.
Microservices architecture
Distributed services with RabbitMQ, Celery, Docker, and Kubernetes. Each service has its own database and API.
Real-time WebSocket backend
WebSocket servers with Django Channels or FastAPI WebSockets for live notifications, chat, and streaming data.
Background job processing
Async task queues with Celery, Redis, and Flower for monitoring. Handles email sends, image processing, and batch jobs.
Data pipeline and ETL backend
ETL pipelines with Airflow, Pandas, and SQLAlchemy that load data from APIs, files, or databases into a warehouse.
Third-party integration backend
Integration layer that connects Stripe, HubSpot, Salesforce, Slack, and Twilio using webhooks and SDKs.
Auth and user management backend
Custom authentication with JWT, OAuth2, social login, and role-based access control (RBAC) using Django Allauth or FastAPI Users.
We build for every business type.
SaaS companies
Fintech and finance
Healthcare and healthtech

Why companies hire professional Python backend development consultants
We ship production-ready Python backends on time and on budget.
IRPR has built over 200 products for clients in 50 countries. Our senior Python engineers deliver clean APIs, robust task queues, and scalable data layers. We use Django, FastAPI, Celery, and PostgreSQL for every backend project.
Every backend we ship includes open-source code in your GitHub repo, a CI/CD pipeline with GitHub Actions, and monitoring with Sentry and Datadog. We write unit tests with pytest and achieve 90%+ test coverage before release.
Professional Python backend development consultants vs generic dev shops
Not all agencies are equal. Here is what makes IRPR different.
Generic development shops assign junior engineers, bill hourly, and never commit to a fixed deadline. Their code often has no tests, no documentation, and no CI/CD pipeline.
IRPR works differently. Every project is managed by a senior engineer with 10+ years of Python experience. We give you a fixed price and a fixed timeline from day one.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No test coverage
- No CI/CD pipeline
- No monitoring setup
- Code ownership unclear
- Senior Python developers with 10+ years experience
- Fixed price starting at $80K
- 90%+ test coverage with pytest
- CI/CD on GitHub Actions
- Sentry and Datadog pre-configured
- Full source code ownership
How we build professional Python backends in 12 weeks
Every engagement follows the same proven process: Idea, Roadmap, Product, Release.
We start with a 30-minute discovery call to understand your data model, API requirements, and third-party integrations. If it fits, we propose a paid Roadmap phase.
The Roadmap phase takes one week. We write user stories, design the database schema, choose the async framework, and deliver a fixed quote. Then we build in two-week sprints.
What ships with every professional Python backend
Every backend includes these production essentials.
When you hire IRPR for professional Python backend development consulting, you get more than just code. You get a complete production setup.
We hand over everything a senior team would need to maintain and scale the backend.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions
- PostgreSQL database with migrations (Alembic)
- REST or GraphQL API with OpenAPI/Swagger docs
- Async task queue with Celery and Redis
- Unit tests with 90%+ coverage using pytest
- Logging with structured logs to stdout
- Error tracking with Sentry
- Performance monitoring with Datadog APM
- Docker Compose setup for local development
What we ship in this practice.
Marketplace backend

Fintech payment API
Developed a PCI-DSS compliant payment processing API with FastAPI. Handled 10,000 transactions per minute. Stack: FastAPI, PostgreSQL, Stripe, JWT.
Telemedicine backend
Built a HIPAA-compliant telemedicine backend with Django, Twilio Video, and WebRTC. Enabled 500+ virtual consultations per day. Stack: Django, Twilio, PostgreSQL, Celery.
SaaS subscription backend
Implemented a multi-tenant subscription system with Django and Stripe Billing. Reduced churn by 15% through usage-based billing. Stack: Django, Stripe, PostgreSQL, Celery.
Real-time analytics backend
Built a WebSocket-driven analytics dashboard with FastAPI and TimescaleDB. Streamed 10,000 events per second. Stack: FastAPI, WebSockets, TimescaleDB, Redis.
LMS backend with FERPA compliance
Created a learning management backend with Django and PostgreSQL. Integrated with Canvas API for roster sync. Stack: Django, PostgreSQL, Celery, Canvas API.
Why teams hire us.
Fixed price, not hourly billing
Every project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
IRPR does not hire juniors. Every engineer has 10+ years of experience with Python, Django, FastAPI, and distributed systems.
Production-ready from day one
We ship monitoring, logging, CI/CD, and 90%+ test coverage. You get a backend that is ready for production traffic from the first release.
Full source code ownership
You own all the code we write. No licensing, no restrictions. The code lives in your GitHub repository from the start.
Async-native architecture
We use asynchronous patterns with FastAPI and Celery. Your backend can handle tens of thousands of concurrent requests without blocking.
Compliance built in
We have built backends for HIPAA, PCI-DSS, SOC 2, and FERPA compliance. The data models, encryption, and audit logs are part of the architecture.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
