Expert Python Backend Development PartnerPartner
Build your MVP in 8-12 weeks. Senior Python engineers, fixed price, no fluff.
IRPR is an expert Python backend development partner for companies that need production-grade backends, not prototypes. We build with Django, FastAPI, Flask, Celery, Redis, PostgreSQL, and deploy on AWS or GCP with CI/CD pipelines out of the box.
Every engagement uses our Idea-Roadmap-Product-Release framework. The average MVP ships in 8-12 weeks at a fixed price between $80K and $250K. Our senior engineers handle your compliance requirements including HIPAA, PCI-DSS, and SOC 2.
Founders hire us when they need a scalable backend that investors can trust. CTOs hire us to offload core API development while keeping their internal team focused on the frontend. Product managers hire us when they need a technical partner who delivers on time.

Why you need an expert Python backend development partner
A production backend requires more than a single Flask script it needs async workers, caching, database optimization, and security hardening.
Python is the most popular language for backend APIs, but scaling it demands senior engineers who understand thread safety, query optimization, and deployment. IRPR has shipped 200+ Python backends for clients in 50 countries including healthcare, fintech, and SaaS.
Our backends average 99.9% uptime because we use proper error tracking with Sentry, centralized logging with ELK stack, and load testing with Locust before release. Every project includes a staging environment and a production deployment playbook.
How IRPR differs from a generic development shop
Most agencies bill hourly, write spaghetti code, and vanish after launch. IRPR treats your backend like a product.
We start with a Roadmap phase where we whiteboard your data model, API endpoints, and deployment architecture. You get a fixed price before a single line of code is written.
Our senior engineers use a standard toolchain: Python 3.12+, Django or FastAPI, PostgreSQL, Redis, Celery, Docker, GitHub Actions, and AWS or GCP. Every commit runs linting and tests automatically.
- Hourly billing with unclear scope
- Junior developers learning on your dime
- No CI/CD or automated testing
- Uses whatever stack the freelancer knows
- No documentation until you ask for it
- Handoff without ownership transfer
- Fixed price agreed in week 2
- Senior engineers with 10+ years experience
- CI/CD pipeline on GitHub Actions from day one
- Django, FastAPI, or Flask per your needs
- API docs auto-generated from code
- Full source code ownership and clean handoff
Our 4-phase process for building your Python backend
From idea to production release, every project follows a repeatable 4-stage framework.
Phase 1: Idea. We clarify your core use cases, data requirements, and success metrics. This takes 1-2 days of discovery calls and async collaboration.
Phase 2: Roadmap. We produce a detailed technical specification with database schema, API contract, deployment plan, and a fixed price. You approve before we build.
What ships with every Python backend
You get a production-ready system, not a code dump.
Every deliverable includes the same foundational components so you can go live immediately or hand off to your internal team.
Our checklists ensures nothing is missed authentication, logging, testing, and deployment are always included.
- Source code in your Git repository
- CI/CD pipeline on GitHub Actions with automated tests
- API documentation via Swagger UI or ReDoc
- PostgreSQL database with migration scripts
- Redis caching layer for performance
- Celery task queue for background jobs
- Sentry error tracking and performance monitoring
- Docker Compose for local development
- Staging environment on AWS or GCP
- Production deployment runbook and architecture diagram
What we ship in this practice.
SaaS subscription platform
Built a Django REST backend with Stripe integration, Celery for invoice generation, and JWT authentication. Reduced payment processing time by 40%. Tech stack: Django, PostgreSQL, Stripe, Celery, Redis.
Real-time analytics dashboard
Constructed a FastAPI backend with WebSocket endpoints streaming event data to a React frontend. Handled 10,000 concurrent connections with 200ms latency. Tech stack: FastAPI, Redis Pub/Sub, PostgreSQL, WebSockets.
HIPAA-compliant patient portal
Developed a Django backend with FHIR API integration, end-to-end encryption, and audit logging. Achieved HIPAA compliance in 10 weeks. Tech stack: Django, FHIR, PostgreSQL, AWS KMS, CloudWatch.
Multi-vendor ecommerce marketplace
Built a microservices backend using FastAPI with PostgreSQL sharding and RabbitMQ for order processing. Supported 500+ vendors with zero downtime during Black Friday. Tech stack: FastAPI, PostgreSQL, RabbitMQ, Docker, Kubernetes.
Payment processing API for fintech
Created a PCI-DSS compliant Flask backend integrated with Stripe Connect and Plaid for bank accounts. Processed $2M in transactions in the first month. Tech stack: Flask, Stripe Connect, Plaid, PostgreSQL, Redis.
ML model inference service
Designed a FastAPI backend with Celery-based async inference queue for image classification models. Reduced model response time from 5 seconds to 800ms with caching. Tech stack: FastAPI, Celery, Redis, TensorFlow, Docker.
Why teams hire us.
Senior engineers only
Our team averages 12 years of Python experience. No juniors, no subcontractors. Every engineer writes clean, typed, and tested code that your team can maintain.
Fixed price from the start
After the Roadmap phase (week 2), you get a fixed quote. No hourly billing. No scope creep fees. The price you see is the price you pay.
8-12 week MVP delivery
Most backends ship in 8-12 weeks. We use Django's admin panel, FastAPI's auto-generated docs, and Celery for async to move fast without cutting corners.
Compliance built in
We handle HIPAA, PCI-DSS, and SOC 2 as part of the build. Encryption, audit logs, and role-based access are included by default, not added later.
CI/CD from day one
Every project starts with a GitHub Actions pipeline that runs linting, tests, and deploys to staging. You see real progress every 2 weeks.
Full ownership transfer
You own 100% of the source code, documentation, and deployment scripts. No licensing, no lock-in. We hand over everything you need to run the backend yourself.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
