Leading Python Backend Development ConsultantsBackend Consultants
We build production-grade Python backends that scale. 12-week delivery with fixed pricing.
IRPR builds Python backends for web apps, mobile APIs, and data pipelines. We use FastAPI, Django, Celery, PostgreSQL, and Redis to handle high concurrency and complex business logic.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, and SOC 2 out of the box.
CTOs hire us when their in-house team lacks Python depth. Startup founders use us to launch MVPs fast. Enterprise teams bring us in for backend architecture rewrites. Series A startups contract us for scalable API design.

Why leading python backend development consultants matter
Your backend is the foundation of every user action and data transaction.
A poorly designed Python backend causes slow responses, data loss, and scaling failures. IRPR's senior engineers build backends that handle 10,000+ requests per second with 99.9% uptime. We use FastAPI for high performance and Celery for background tasks.
We have shipped over 200 products across 50 countries. Our backends power fintech apps processing $50M in monthly transactions and healthcare platforms handling 1M patient records. Every project includes automated testing, CI/CD pipelines, and monitoring with Sentry and Datadog.
Generic dev shops vs leading python backend development consultants
Not all Python shops deliver production-grade systems.
Many agencies quote low prices but hand you junior developers who write unmaintainable code. They skip testing, ignore security, and leave you with a backend that crashes under load.
IRPR assigns senior engineers with 8+ years of Python experience. We write unit tests, integration tests, and load tests. Every backend ships with a CI/CD pipeline, error tracking, and a documented API.
- Junior developers with 1-2 years experience
- No automated testing
- No CI/CD pipeline
- No monitoring or error tracking
- Hourly billing with scope creep
- No compliance documentation
- Senior engineers with 8+ years Python experience
- Unit, integration, and load tests included
- CI/CD pipeline on GitHub Actions
- Sentry and Datadog monitoring
- Fixed price, no surprises
- HIPAA, PCI-DSS, SOC 2 compliance
How we build your Python backend
Our process is designed for speed and quality.
We start with a 2-week Roadmap phase where we define the architecture, data model, and API endpoints. You get a fixed price quote and a detailed timeline before any development begins.
After approval, we build in 2-week sprints with demos every Friday. You see working code from week 3. We deploy to staging by week 6 and production by week 12.
What ships with your Python backend
You get more than just code.
Every project includes a full deployment package. No hidden deliverables. No missing pieces.
Your team can take over maintenance immediately because everything is documented and automated.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions
- Automated unit and integration tests (200+ tests minimum)
- Sentry error tracking and Datadog monitoring
- API documentation with Swagger
- Database schema and migration scripts
- Deployment playbook with rollback steps
- Load test results with k6
- Postman collection for all endpoints
What we ship in this practice.
Telemedicine platform backend
Built a HIPAA-compliant backend with FastAPI and PostgreSQL for a telemedicine startup. Reduced patient data retrieval time by 60%. Handles 5,000 concurrent video sessions.
Lending platform API
Developed a PCI-DSS compliant Python backend for a fintech lender. Integrated with Stripe, Plaid, and credit bureaus. Processed $2M in loans in the first month.
Ecommerce recommendation engine
Built a real-time recommendation API using FastAPI and Redis. Increased average order value by 18% for a mid-market retailer. Handles 10,000 requests per second.
Multi-tenant SaaS backend
Designed a multi-tenant architecture with Django and PostgreSQL for a B2B SaaS platform. Supports 500 tenants with isolated data. Zero downtime deployments.
MLS data integration API
Created a Python backend that ingests MLS data from 50 sources in real-time. Reduced data latency from 4 hours to 5 minutes for a real estate platform.
Manufacturing data pipeline
Built an ETL pipeline with Apache Airflow and Python for a factory. Aggregates sensor data from 1,000 machines. Reduced reporting time from 1 week to 1 hour.
Why teams hire us.
Senior engineers only
Every developer on your project has 8+ years of Python experience. No juniors. No offshore teams. You get a lead engineer who owns the architecture end-to-end.
Fixed price, not hourly
You get a fixed quote after the 2-week Roadmap phase. No hourly billing. No surprise invoices. The price is locked from week 2.
12-week delivery guarantee
We ship a production-ready backend in 12 weeks or less. We have a 98% on-time delivery record across 200+ projects. If we miss the deadline, we discount the next sprint.
Full code ownership
You own every line of code from day 1. No licensing fees. No vendor lock-in. You can take the code to any team after we ship.
Built-in compliance
We handle HIPAA, PCI-DSS, and SOC 2 compliance out of the box. Every backend includes audit logs, encryption at rest, and role-based access control.
Production monitoring included
We set up Sentry error tracking and Datadog monitoring before launch. You get real-time alerts on errors, latency, and uptime from day 1.
