Python Backend Development CompanyDevelopment Company
We build Python backends that scale from launch to millions of users. Senior engineers only, fixed price, 8-12 week MVP delivery.
IRPR is a Python backend development company that builds production-ready APIs, microservices, and data pipelines using Django, FastAPI, Flask, Celery, and PostgreSQL. Every project deploys on AWS or GCP with Docker and Kubernetes for scaling.
We ship a working MVP in 8-12 weeks, with a fixed price range of $80K-$250K depending on scope. All projects meet compliance requirements: HIPAA for healthcare, PCI-DSS for fintech, SOC 2 for SaaS, and FERPA for edtech.
CTOs scaling their backend from prototype to production hire us. Product managers at mid-market companies needing a dedicated Python team hire us. Founders who need a fast, compliant backend for their MVP hire us. Enterprise teams offloading backend development to senior engineers hire us.

Why you need a dedicated Python backend development company
A poorly built backend costs more in the long run. IRPR delivers clean, scalable code from day one.
Python is the most popular language for backend systems, but building a production-grade backend requires deep expertise in async programming, database optimization, and cloud infrastructure. A generic agency might copy-paste code from tutorials, leaving you with security holes and scaling nightmares. IRPR designs each backend around your specific data model and traffic pattern.
We use FastAPI for high-throughput APIs, Django for feature-rich applications, and Celery for background tasks. Every microservice includes health checks, structured logging, and distributed tracing with OpenTelemetry. Our teams have built backends that handle 10,000+ requests per second on a single AWS environment.
The IRPR difference for Python backend development
Most dev shops bill hourly and deliver late. IRPR works differently.
Generic dev shops often assign junior developers who learn on your dime. They change requirements mid-project, bill for every extra call, and deliver spaghetti code that collapses under load. IRPR assigns senior engineers only, with an average of 10+ years of Python experience.
We use a fixed-price model. After a 2-week Roadmap phase, you get a clear scope, timeline, and price. No hourly billing. No scope creep. Every project includes CI/CD, automated tests, and monitoring from day one.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No testing or CI/CD
- No compliance knowledge (HIPAA, PCI)
- Slow communication via account managers
- Code ownership unclear
- Senior engineers only, avg 10+ years Python
- Fixed price from Roadmap phase (week 2)
- Automated CI/CD with GitHub Actions
- HIPAA, PCI-DSS, SOC 2 compliant by default
- Direct Slack channel with the team
- Full source code ownership, no IP restrictions
How we build your Python backend in 12 weeks
Our process is designed for speed and transparency. You see working software every two weeks.
Phase 1 (week 1-2): Discovery and Roadmap. We analyze your requirements, data model, and expected traffic. You get a 10-page technical specification with architecture diagrams, a fixed price, and a timeline. Phase 2 (week 3-10): Core development in 2-week sprints with demos at the end of each sprint. Phase 3 (week 11-12): Final integration, load testing, and deployment to production.
Each sprint delivers a working increment: endpoints, database migrations, and frontend integration points. You test in a staging environment that mirrors production. We use feature flags so you can roll out gradually.
What ships with every Python backend project
You get more than just code. Every project ships with production-ready infrastructure and documentation.
We don't throw code over the wall. Every backend comes with a full DevOps setup, including CI/CD pipelines, monitoring, and deployment scripts. Your team can take over immediately without guesswork.
The checklist below shows every deliverable you receive at the end of a project. No hidden items. No extras to buy later.
- Source code in your GitHub/GitLab repo
- CI/CD pipeline using GitHub Actions or GitLab CI
- Docker Compose for local development
- Kubernetes manifests for production staging
- PostgreSQL schema with migration scripts (Alembic)
- API documentation auto-generated with Swagger/ReDoc
- Health check endpoints and metric collection (Prometheus)
- Sentry error tracking and logging (ELK stack)
- Automated test suite (pytest, 80%+ coverage)
- Post-launch 2-week warranty and 1 year of infrastructure support
What we ship in this practice.
Fintech payment processing backend
Built a PCI-DSS compliant payment gateway using FastAPI and Stripe. Handles 5,000 transactions per second with idempotent endpoints. Reduced failed payments by 40%.
Healthcare telemedicine platform
Developed a HIPAA-compliant backend with Django and WebRTC. Manages 50,000 patient records and supports 1,000 concurrent video calls. Deployed on AWS with encrypted storage.
SaaS analytics dashboard
Created a real-time analytics backend using FastAPI and WebSockets. Ingests 1 million events per minute into ClickHouse and serves dashboards with sub-second latency.
Ecommerce inventory management
Built a multi-warehouse inventory backend with Django and Celery. Syncs stock levels across 20 stores in real-time. Reduced overselling incidents by 99%.
EdTech assessment platform
Developed a FERPA-compliant backend using Django and PostgreSQL. Supports 10,000 concurrent students taking timed exams. Automated grading and reporting.
Real estate data aggregation API
Created a Python backend that scrapes and normalizes MLS listings from 50 providers. Serves unified property data via FastAPI to 3 client apps. Cut integration time from 6 months to 8 weeks.
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. You know the cost upfront.
Senior engineers only
IRPR hires engineers with 10+ years of Python experience. No juniors. You work directly with the person writing your code, not an account manager.
8-12 week MVPs
We ship a working backend in 8-12 weeks. Faster than hiring in-house and cheaper than a co-founder. You can start selling immediately.
Full code ownership
You own all source code, documentation, and infrastructure scripts. No licenses, no royalties, no lock-in. Take your code anywhere.
Compliance built in
We build to HIPAA, PCI-DSS, SOC 2, and FERPA standards from the start. Audit logs, encryption, and access controls are default, not add-ons.
200+ products shipped
IRPR has delivered 200+ products to clients in 50+ countries. Our teams have deep experience scaling Python backends from zero to millions of users.
