Professional Python Backend Development FirmBackend Development
We build scalable APIs, microservices, and data pipelines. Ship your production-ready backend in 8-12 weeks with fixed pricing.
IRPR builds professional Python backend systems for startups and enterprises. We use Django, FastAPI, and PostgreSQL to build APIs, microservices, and data pipelines.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. Our backends handle 99.9% uptime and pass HIPAA, SOC 2, and PCI DSS audits.
We work with CTOs building new products, founders launching SaaS platforms, engineering leads migrating from monoliths to microservices, and product teams needing scalable data infrastructure.
Types of software we ship.
REST API
Build RESTful APIs with Django REST Framework or FastAPI. Includes versioning, pagination, and OpenAPI documentation.
GraphQL API
GraphQL backends using Strawberry or Apollo. Resolvers, subscriptions, and real-time data fetching.

Why hire a professional Python backend development firm?
IRPR has shipped 200+ backends for companies in 50+ countries.
We focus on Python because it powers the most reliable backends in fintech, healthcare, and SaaS. Our engineers average 10+ years of Python experience.
Every backend includes automated testing, CI/CD via GitHub Actions, and 99.9% uptime SLA. We use Sentry for error tracking and Datadog for monitoring.
Generic dev shop vs IRPR
Not all Python development firms deliver production-ready backends.
Generic shops often use boilerplate code and skip testing. You get an API that works but breaks under load.
IRPR builds for scale from day one. We write tests, set up monitoring, and document every endpoint. You get a backend that handles 10x growth without rewrites.
- No automated tests
- No monitoring or alerts
- No CI/CD pipeline
- Undocumented APIs
- Long timelines, hourly billing
- No performance testing
- Full test coverage (pytest, 80%+)
- Datadog + Sentry monitoring
- GitHub Actions CI/CD
- OpenAPI/GraphQL schema docs
- Fixed-price, 8-12 week delivery
- Load testing with Locust
How we build your Python backend
Our process from idea to production takes 8-12 weeks.
We start with a 2-week Roadmap phase where we define the API endpoints, data model, and tech stack. You get a fixed price and timeline.
Then we build in 2-week sprints with demos every sprint. You see working code from week 3. Final release includes deployment to AWS, GCP, or Azure.
What ships with your Python backend
Every project includes these deliverables by default.
No hidden extras. Everything listed here is part of the fixed price.
You own all code, documentation, and deployment scripts.
- Source code in private GitHub repo
- CI/CD pipeline (GitHub Actions)
- Automated tests (pytest, 200+ tests average)
- API documentation (OpenAPI/Swagger)
- Docker containers for local dev and prod
- Monitoring setup (Datadog + Sentry)
- Deployment scripts (Terraform or Pulumi)
- Production database (PostgreSQL with backups)
- Load testing report (Locust)
- Post-launch support (2-week warranty)
What we ship in this practice.
Payment processing API for a fintech startup
Built a PCI DSS compliant payment gateway using Django, Stripe, and PostgreSQL. Reduced transaction failures by 40% and passed security audit in 2 weeks.
EHR data pipeline for a telemedicine platform
Developed a HIPAA compliant data pipeline using FastAPI and Apache Airflow. Processed 1 million patient records daily with 99.99% accuracy.
Multi-tenant SaaS backend for a CRM tool
Created a scalable backend with Django REST Framework and PostgreSQL. Supported 500 tenants on a single instance, reducing infrastructure costs by 60%.
Real-time inventory system for e-commerce
Built WebSocket-based inventory tracking using FastAPI and Redis. Cut stock discrepancies from 5% to 0.2% and handled 10,000 concurrent users.
ML model serving API for a recommendation engine
Deployed a TensorFlow model using FastAPI and Kubernetes. Achieved 50ms inference time and scaled to 1 million requests per day.
Authentication microservice for a B2B platform
Designed an OAuth 2.0 server with Django and Auth0. Supported SSO for 100+ enterprise clients and passed SOC 2 audit.
Why teams hire us.
Fixed price, not hourly
Every Python backend project gets a fixed quote after the Roadmap phase. No surprise invoices or scope creep charges.
Senior engineers only
Our team averages 10+ years of Python experience. Every backend is built by a senior engineer, not a junior or offshore team.
Production-ready from day one
We include tests, monitoring, CI/CD, and documentation in every project. Your backend is ready for production on release day.
Compliance built in
We build backends that pass HIPAA, SOC 2, PCI DSS, and FERPA audits. Our infrastructure uses encrypted databases, audit logs, and role-based access.
12-week average delivery
Most backends ship in 8-12 weeks. We use Django and FastAPI to accelerate development without sacrificing quality.
Full code ownership
You own every line of code, every deployment script, and every document. No lock-in, no licensing fees, no monthly retainers.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
