Best Python Backend Development VendorDevelopment Vendor
IRPR builds production-ready Python backends in 8-12 weeks. Fixed pricing means no surprise invoices.
IRPR builds Python backends for web apps, APIs, and data pipelines using Django, FastAPI, or Flask. Every project starts with a detailed Roadmap that defines architecture, database schema, and API contracts before a single line of code is written.
We ship complete backend systems including REST/GraphQL APIs, database models, authentication, background workers, and CI/CD pipelines. Typical timelines are 8-12 weeks with fixed prices from $80K to $250K. All projects comply with SOC 2, HIPAA, or PCI-DSS where required.
SaaS founders hire us to build scalable APIs that handle thousands of requests per second. Healthcare companies need HIPAA-compliant backends with audit logging. Fintech startups require PCI-DSS level 1 ready architectures. E-commerce brands want high-performance backends that integrate with Stripe and Shopify.
Types of software we ship.
REST API Development
Build RESTful APIs with Django REST Framework or FastAPI. Supports OAuth2, JWT, rate limiting, and Swagger docs.

Why IRPR is the best Python backend development vendor
We focus on clean architecture, automated testing, and production readiness from day one.
Every Python backend we build includes unit tests, integration tests, and end-to-end tests. We enforce 90%+ code coverage and use GitHub Actions for CI/CD. Deployments are automated to AWS, GCP, or Azure.
Our team of senior Python engineers has shipped over 200 products across 50 countries. We follow the same process every time: Idea, Roadmap, Product, Release. This guarantees predictable timelines and budgets.
Generic dev shop vs the best Python backend vendor
Not all firms deliver clean, scalable code. Here is how we compare.
Generic shops often hand you code with no tests, no CI/CD, and no documentation. They bill by the hour and keep your code hostage. You are left with a fragile backend and no clear path to launch.
IRPR gives you a fixed price, full code ownership, and a production-ready Python backend with automated testing, monitoring, and documentation. We hand over the repo on day 1 of the build.
- Hourly billing causes budget overruns
- No automated tests
- No CI/CD pipeline
- Code hosted on their infrastructure
- No post-launch handover plan
- Vague documentation, if any
- Fixed price from the Roadmap phase
- 90%+ code coverage with pytest
- CI/CD on GitHub Actions
- Code in your repo from day 1
- Full handover including runbooks
- OpenAPI docs generated automatically
Our process for building your Python backend
We follow four phases to deliver a backend you can deploy on day 1.
Each phase has clear deliverables and a fixed price. The Roadmap phase (week 2) gives you an architecture diagram, database schema, API endpoints, and a timeline. After that, we build and test in sprints.
You get a staging environment after week 4 and a production-ready backend by week 8-12. We also include a 2-week warranty and optional post-launch support.
What ships with every Python backend from IRPR
Your project includes everything needed to run and maintain an enterprise-grade backend.
We do not just deliver code. Every backend comes with a full testing suite, CI/CD pipelines, monitoring, and operational runbooks. Your team can start contributing immediately.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions, CircleCI, or GitLab CI
- Unit tests (pytest) with 90%+ coverage
- Integration tests for all API endpoints
- API documentation (OpenAPI/Swagger)
- Database migration scripts (Alembic)
- Docker Compose and Dockerfile for local dev
- Deployment playbooks (Terraform or Pulumi)
- Error monitoring with Sentry
- Performance monitoring with Datadog or New Relic
What we ship in this practice.
SaaS API for a booking platform
We built a Django REST API handling 500+ requests/second with PostgreSQL and Redis caching. The client launched in 10 weeks and onboarded 2000 users in month one. Stack: Django, Django REST Framework, Celery, PostgreSQL.
HIPAA-compliant patient data backend
A telemedicine startup needed a secure backend with encryption at rest and in transit. IRPR delivered a FastAPI backend with FHIR integration and audit logs. The solution passed a HIPAA audit with zero findings. Stack: FastAPI, PostgreSQL, Alembic, AWS KMS.
PCI-DSS level 1 payment processing backend
A fintech company required a PCI-compliant backend to process 100K transactions/day. We built a microservices architecture with Django and Stripe Connect. The system went live in 12 weeks with zero security incidents. Stack: Django, Stripe, RabbitMQ, Docker.
E-commerce backend with multi-warehouse inventory
An online retailer needed real-time inventory sync across 10 warehouses. IRPR built a FastAPI backend with WebSocket updates and Elasticsearch for search. The client reduced order errors by 95%. Stack: FastAPI, PostgreSQL, Elasticsearch, Redis.
Real-time analytics pipeline for media platform
A media company needed to process 5 million events/day for personalized recommendations. We deployed an Apache Airflow pipeline with Python and Spark. The pipeline runs on AWS EMR and costs 40% less than their previous solution. Stack: Airflow, Spark, Python, AWS S3, Redshift.
Logistics backend with route optimization
A last-mile delivery company needed a backend to optimize 1000+ routes daily. IRPR built a Django backend with OR-Tools for route optimization and integrated it with Google Maps API. Delivery times dropped by 18%. Stack: Django, PostgreSQL, OR-Tools, Google Maps API.
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. Price stays locked from start to finish.
Senior engineers only
Our team averages 10+ years of Python experience. You never get junior developers. Every line of code is written by senior engineers who have shipped backends for startups and Fortune 500 companies.
Full code ownership from day 1
We create a private repo in your own GitHub account on the first day of the build phase. You own all source code, documentation, and deployment scripts. No licensing fees or vendor lock-in.
Production-ready from day 1 of release
We ship backends running on HTTPS with TLS, environment variable management, database backups, and monitoring. You can deploy to production within hours of handover.
Compliance built-in
We implement SOC 2, HIPAA, PCI-DSS, or FERPA controls as part of the architecture. We have built compliant backends for healthcare, fintech, and education clients. No bolt-on security.
8-12 week MVP timeline
Most projects go from roadmap to release in less than 3 months. We optimize for speed without cutting corners. If you need an MVP faster, we can deliver a functional prototype in 6 weeks.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
