Python Backend Development ServicesDevelopment Services
We build scalable Python backends that ship in 8-12 weeks. Fixed price, full code ownership, no surprises.
IRPR builds Python backend development services for startups and mid-market companies that need production-ready APIs, microservices, and data pipelines. We use FastAPI for high-performance REST and GraphQL endpoints, Django for full-stack admin panels, and Celery for async task processing. Every backend ships with automated tests, CI/CD pipelines, and monitoring via Sentry and Datadog.
A typical Python backend ships in 12-14 weeks with a fixed price between $80K and $250K depending on complexity. Our backends handle HIPAA compliance for healthcare, PCI-DSS for fintech, and SOC 2 for SaaS platforms. We provide full code ownership, no black-box modules, and a 98% on-time delivery rate.
CTOs hire us when their in-house team is overloaded and they need a second engineering squad. Technical founders come to us to build their first backend while they focus on fundraising. Product managers engage us to add a new microservice or migrate from a monolithic PHP or Node.js backend to Python for better performance and developer productivity.
Types of software we ship.
REST API development
Build stateless RESTful APIs with FastAPI or Django REST Framework. Includes OpenAPI docs, JWT auth, and rate limiting.

Why Python is the right choice for your backend
Python powers the backends of Instagram, Spotify, and Dropbox. Here is why it works for your next product.
Python is the second most used language on GitHub and has the largest package ecosystem with over 500,000 packages on PyPI. Frameworks like FastAPI and Django let you build APIs 3x faster than with Java or Go. IRPR uses Python for all backend projects because it reduces time to market and makes hiring easier.
Python backends scale horizontally. We use async workers with Uvicorn and Gunicorn to handle thousands of requests per second. With PostgreSQL and Redis caching, a single Python service can serve 10,000+ concurrent users before needing a second node. Our team has shipped Python backends for companies processing over $50M in annual transactions.
How IRPR is different from other Python backend agencies
Most dev shops bill hourly and hand you half-finished code. We do the opposite.
We built our process over 200+ projects. Every Python backend starts with a 2-week Roadmap phase where we define the database schema, API endpoints, and deployment architecture. You get a fixed price quote before any code is written. No hourly billing, no surprise overruns.
Your code lives in your own GitHub repo from day one. We set up CI/CD with GitHub Actions, automated tests with pytest, and error tracking with Sentry. When the project ends, you own everything - source code, documentation, infrastructure scripts, and deployment pipelines. No lock-in, no recurring fees.
- Hourly billing with unpredictable costs
- No fixed scope or timeline
- Code stays in their repo until fully paid
- No automated tests or CI/CD
- Handoff without documentation
- No post-launch support
- Fixed price from week 2
- 8-12 week delivery guarantee
- Code in your repo from day 1
- pytest, GitHub Actions, Sentry included
- Full architecture docs and README
- 2 weeks of free production support
Our 4-phase process for Python backend development
We follow a repeatable process that eliminates guesswork and keeps your project on track.
Every Python backend project at IRPR goes through four phases. Each phase ends with a deliverable you can review and approve. This keeps the project predictable and prevents scope creep.
The process works for startups launching their first product and for enterprises adding a new service. Our 98% on-time record comes from this structure.
What ships with every Python backend
Every project includes these deliverables by default. No hidden add-ons or extra charges.
We ship more than just code. Every Python backend comes with infrastructure, documentation, and monitoring tools that let your team take over immediately. Our goal is to make you self-sufficient from day one.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated test suite with pytest (90%+ coverage)
- API documentation via OpenAPI/Swagger
- Docker Compose and Dockerfile for local dev
- Terraform scripts for cloud infrastructure
- Sentry error tracking and Datadog monitoring
- Database migration scripts with Alembic
- Architecture diagram and README
- Post-launch support for 2 weeks
What we ship in this practice.
SaaS subscription API
Built a FastAPI backend with Stripe integration for a B2B SaaS platform. The system handles 50,000 daily API calls, manages tiered subscription plans, and sends automated invoices. Reduced billing errors by 90%. Tech stack: FastAPI, PostgreSQL, Stripe, Redis.
Healthcare patient portal backend
Developed a HIPAA-compliant Django backend for a telemedicine startup. The API manages patient records, appointment scheduling, and video call tokens. Handles 10,000 active patients with sub-200ms response times. Tech stack: Django, PostgreSQL, Twilio, AWS HealthLake.
Ecommerce order processing pipeline
Created a Celery-based order processing system for a fashion retailer. The pipeline ingests orders from Shopify, validates inventory, and updates shipping status. Processes 5,000 orders per hour during Black Friday. Tech stack: Django, Celery, Redis, Shopify API.
Fintech payment gateway API
Built a PCI-DSS compliant FastAPI backend for a payment processing platform. The API handles card tokenization, transaction routing, and fraud scoring. Achieves 99.99% uptime with sub-100ms latency. Tech stack: FastAPI, PostgreSQL, Stripe, Plaid.
Real-time analytics dashboard backend
Developed a WebSocket server with FastAPI for a live analytics dashboard. The system streams event data from 10,000 connected devices and updates visualizations in real time. Reduced data refresh latency from 30 seconds to 200ms. Tech stack: FastAPI, WebSockets, Redis, TimescaleDB.
ML model serving API
Created a serverless Python backend on AWS Lambda to serve a fraud detection model. The API accepts transaction data, runs inference via a pre-trained XGBoost model, and returns a risk score in under 50ms. Handles 1,000 requests per second. Tech stack: FastAPI, AWS Lambda, S3, XGBoost.
Why teams hire us.
Fixed price, not hourly
Every Python backend project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. If we need more features, we quote a new phase.
Senior engineers only
Our team averages 10+ years of Python experience. Every engineer has shipped production backends for companies like Netflix and Uber. No juniors, no offshore interns.
Code ownership from day one
Your code lives in your GitHub repository from the first commit. We never hold code hostage. You can fire us at any time and keep everything we built.
Production-ready from sprint 1
We write tests, set up CI/CD, and configure monitoring from the first sprint. Your backend is deployable to production after 4 weeks, not after 6 months.
Compliance built in
We have built HIPAA, PCI-DSS, SOC 2, and FERPA compliant backends. Our engineers know how to handle PHI, PII, and payment data without cutting corners.
98% on-time delivery
We have delivered 200+ projects and 98% shipped on time. Our process eliminates guesswork. We over-communicate and ship every 2 weeks.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
