Best Python Backend Development PartnerDevelopment Partner
We build production-grade Python backends in 8-12 weeks. Fixed price, senior engineers, no surprises.
IRPR is the best Python backend development partner for companies that need reliable, scalable server-side software. We use Django, FastAPI, Flask, Celery, Redis, PostgreSQL, and AWS to build backends that handle millions of requests per day.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. Our senior engineers write tests, set up CI/CD, and deploy to production.
CTOs hire us when their in-house team is overloaded. Startup founders hire us to build their MVP before fundraising. Enterprise product managers hire us to modernize legacy Python monoliths. We work async-first with daily overlap in US time zones.
Types of software we ship.
REST API development
Build RESTful APIs with Django REST Framework or FastAPI. Includes OpenAPI docs, rate limiting, and JWT auth.
GraphQL backend
GraphQL APIs using Strawberry or Graphene. Single endpoint, typed schemas, real-time subscriptions via WebSockets.
Microservices architecture

Why IRPR is the best Python backend development partner
We have shipped over 200 Python backends for clients in 50+ countries.
Our engineers average 10+ years of Python experience. We use Django for data-heavy apps, FastAPI for high-throughput APIs, and Flask for lightweight services. Every project includes automated tests, CI/CD pipelines, and production monitoring with Sentry and Datadog.
We work in 2-week sprints with weekly demos. Clients see working code every Friday. Our fixed-price model means no budget overruns. The average project ships in 10 weeks.
Generic dev shop vs the best Python backend development partner
Most agencies overpromise and underdeliver. IRPR is different.
Generic dev shops assign junior developers who learn on your dime. They use hourly billing that rewards slow work. They skip testing and monitoring. You get a fragile backend that breaks in production.
IRPR assigns senior engineers only. We use fixed pricing so we are incentivized to ship fast. Every backend includes automated tests, CI/CD, and production monitoring. You own the code from day one.
- Junior developers with 2 years of experience
- Hourly billing with no cap
- No automated tests
- No CI/CD pipeline
- No production monitoring
- You do not own the code
- Senior engineers with 10+ years of Python experience
- Fixed price from $80K to $250K
- 100% test coverage on critical paths
- CI/CD with GitHub Actions and Docker
- Sentry and Datadog monitoring included
- Full code ownership from day one
How we build your Python backend in 4 phases
Our process is designed to de-risk your project from day one.
We start with a 2-week Roadmap phase where we define the architecture, data model, and API contracts. You get a fixed price and timeline before any code is written.
Then we build in 2-week sprints. You see working code every Friday. We deploy to staging after sprint 2 and to production after sprint 4. The average project ships in 10 weeks.
What ships with every Python backend
Every project includes these deliverables by default.
We do not cut corners. Every backend we build is production-ready from day one. You get the source code, infrastructure as code, and monitoring tools.
Our checklist ensures nothing is forgotten. You can deploy to production on day one of the handoff.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and Docker
- Automated test suite with 90%+ coverage
- API documentation with OpenAPI/Swagger
- Database schema and migration scripts
- Production monitoring with Sentry and Datadog
- Infrastructure as code with Terraform or Pulumi
- Deployment runbook and architecture diagrams
- 30 days of post-launch support
- Full code ownership with no licensing fees
What we ship in this practice.
SaaS subscription platform
Built a multi-tenant Django backend with Stripe billing, usage metering, and row-level security. Reduced billing errors by 95% and cut customer churn by 12% in the first quarter. Tech stack: Django, PostgreSQL, Stripe, Redis.
Real-time fraud detection API
Developed a FastAPI backend that processes 10,000 transactions per second with sub-100ms latency. Integrated with machine learning models for real-time scoring. Reduced fraud losses by 40%. Tech stack: FastAPI, Kafka, Redis, PostgreSQL.
HIPAA-compliant telemedicine backend
Built a Django backend for a telemedicine platform handling 50,000 patient visits per month. Implemented end-to-end encryption, audit logging, and role-based access control. Passed HIPAA audit on first attempt. Tech stack: Django, PostgreSQL, AWS, Twilio.
Headless ecommerce backend
Created a headless ecommerce backend using Django Oscar and GraphQL. Integrated with Shopify for inventory sync and Stripe for payments. Reduced page load time by 60% and increased conversion rate by 15%. Tech stack: Django, GraphQL, Stripe, Redis.
Real estate MLS data pipeline
Built a data pipeline that ingests MLS listings from 50+ sources in real time. Normalizes and deduplicates data using Celery and Redis. Reduced data latency from 24 hours to 5 minutes. Tech stack: FastAPI, Celery, Redis, PostgreSQL.
EdTech assessment platform
Developed a FERPA-compliant backend for a K-12 assessment platform. Handles 1 million concurrent users during peak testing periods. Automated grading reduced teacher workload by 8 hours per week. Tech stack: Django, PostgreSQL, Redis, AWS.
Why teams hire us.
Senior engineers only
Every engineer on your project has 10+ years of Python experience. No juniors, no offshore interns. You get a lead engineer who has shipped production backends for companies like Stripe and Airbnb.
Fixed price, not hourly
We quote a fixed price in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. If we find a better way to build something, we do it at no extra cost.
8-12 week MVPs
We ship production-ready backends in 8-12 weeks. Our record is 6 weeks for a FastAPI-based payment API. You get a deployable product, not a prototype.
Full code ownership
You own every line of code from day one. No licensing fees, no lock-in, no hidden costs. We put the source code in your GitHub repo on day one of development.
Production-grade from day one
Every backend includes automated tests, CI/CD, monitoring, and infrastructure as code. We deploy to production with Sentry error tracking and Datadog dashboards. Your team can take over immediately.
Compliance built in
We build backends that pass HIPAA, PCI-DSS, SOC 2, and FERPA audits. Our engineers know the compliance requirements for healthcare, fintech, and education. We include audit logging, encryption, and access controls by default.
