Professional Python Backend Development VendorBackend Development
We build production-ready Python backends with Django, FastAPI, and Flask. Fixed pricing from $80K, delivery in 8-12 weeks.
IRPR is a professional Python backend development vendor. We use Python 3.12, Django 5, FastAPI, Flask, Celery, PostgreSQL, Redis, and Docker to build backends that handle millions of requests per day.
Every project ships with a fixed price and a clear timeline. You get a Roadmap (your second week), then a production-ready backend in 8-12 weeks. Pricing starts at $80K and runs to $250K. We handle PCI-DSS, HIPAA, and SOC 2 compliance when needed.
We work with CTOs who need a reliable backend for their SaaS product, founders launching a fintech or health platform, engineering leads scaling an ecommerce application, and product managers replacing a broken legacy API.

What a Professional Python Backend Development Vendor Delivers
IRPR ships more than code. Every backend comes with infrastructure, monitoring, and documentation.
We write Python 3.12 with type hints and async support. Your backend includes automated tests (pytest with 90%+ coverage), CI/CD pipelines on GitHub Actions, and staging and production environments on AWS ECS or DigitalOcean. Every API routes through Cloudflare for DDoS protection.
You receive full admin panels, Swagger/OpenAPI docs, Sentry error tracking, and Datadog performance monitoring. We deploy with Terraform, manage secrets with Vault, and log with ELK stack. All code lives in your private GitHub repo from day one.
Generic Shop vs IRPR: The Python Backend Difference
Not all vendors build production-ready backends. Here is what separates IRPR from the average shop.
We see projects born from freelancers who disappear or agencies that hand off junior devs. IRPR assigns senior Python engineers who stay for the full engagement. You get weekly video demos and a shared Slack channel.
Every backend is built for scale from day one. We use database migrations, connection pooling, and caching layers. No technical debt. No rewrite needed after 3 months.
- No fixed price; hourly billing
- Junior or offshore developers
- No compliance experience
- No CI/CD or monitoring set up
- You own zero infrastructure
- Handoff with no documentation
- Fixed price from $80K
- Senior Python engineers only
- HIPAA, PCI-DSS, SOC 2 ready
- GitHub Actions CI/CD + Sentry monitoring
- Full AWS/DigitalOcean setup owned by you
- OpenAPI docs + deployment runbook
How IRPR Builds Your Python Backend
A four-phase process from idea to production release. Each phase includes a checkpoint and deliverables.
Week 1 is the Idea phase. We scope your requirements, map user flows, and define the data model. For fintech and healthcare projects, we also map compliance needs like HIPAA authentication or PCI card data handling.
Weeks 2-4 are the Roadmap phase. We deliver a project plan with API endpoints, database schema, deployment architecture, and a fixed price. Every API path and integration is documented before any code is written.
What Ships with Your Python Backend
Every project includes these deliverables. No optional extras. All standard.
You own everything. Source code, infrastructure as code, database schema, and monitoring dashboards. IRPR does not keep licenses or proprietary code. You can extend the backend with any developer after launch.
- Python 3.12 source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions (build, test, deploy)
- Docker Compose dev environment and production Docker images
- Automated test suite with pytest (90%+ coverage)
- Sentry error tracking with alerting in your Slack
- Datadog dashboards for latency, CPU, memory, and errors
- Uploaded OpenAPI/Swagger docs for every endpoint
- Database migration scripts (Alembic for SQLAlchemy)
- Terraform scripts for AWS or DigitalOcean infrastructure
- Deployment runbook with rollback, backup, and incident response
What we ship in this practice.
SaaS Subscription Backend
Built a Django backend with Stripe subscription integration, Celery for invoice generation, and Redis caching. The client reduced billing errors by 100% and onboarded 500 users in the first month. Tech: Django 5, Celery, Stripe, PostgreSQL.
HIPAA Patient Portal API
Developed a FastAPI backend with Bcrypt password hashing, role-based access control, and encrypted PHI storage. The portal processed 10K patient records daily with zero compliance issues during audit. Tech: FastAPI, PostgreSQL, AWS KMS, S3.
Fintech Payment Gateway
Created a Flask REST API handling recurring payments, webhooks, and KYC verification. It processed $2M in transactions per month with 99.99% uptime. Tech: Flask, Stripe, Plaid, PostgreSQL, Redis.
Ecommerce Inventory Engine
Built a Python backend with Django, Celery for stock updates, and a GraphQL API for the frontend. It synchronized inventory across 3 warehouses and cut stockout incidents by 70%. Tech: Django, Celery, Ariadne GraphQL, PostgreSQL.
Real-Time Analytics Dashboard
Developed a FastAPI backend with WebSocket support and Kafka for event streaming. The client displayed live metrics to 2000 concurrent users. Tech: FastAPI, Kafka, Redis, PostgreSQL, WebSockets.
Internal Tool API for Logistics
Shipped a Django admin panel and Celery pipeline for route optimization and driver assignment. It reduced manual dispatch work by 12 hours per week. Tech: Django 5, Celery, PostgreSQL, Google Maps API.
Why teams hire us.
Senior engineers only, no juniors
Every IRPR engineer has 8+ years of Python experience. You talk directly to the person writing your code. No account manager. No handoff to a junior team.
Fixed price from the Roadmap phase
You get a fixed price quote in week 2, after the Roadmap phase. No hourly billing. No surprise invoices. The price covers development, deployment, and 30 days of post-release support.
Full ownership of code and infrastructure
We give you everything: source code in your repo, Terraform files for AWS, Docker images, and admin credentials. You can change vendors anytime with zero lock-in.
Production-ready monitoring from day one
Every backend ships with Sentry, Datadog, and Cloudflare. You get alive dashboard and Slack alerts before your first user hits the API.
Compliance built in, not bolted on
We build HIPAA, PCI-DSS, and SOC 2 controls into the architecture. For example, HIPAA projects use AWS KMS for encryption and audit logs. No retrofitting after launch.
Proven track record with 200+ products
IRPR has shipped 200+ Python backends to clients in 50+ countries. Our on-time rate is 98%. We do not take projects that we cannot finish on schedule.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
