Python Backend Development FirmDevelopment Firm
We build scalable Python backends for web apps, APIs, and microservices. Get an MVP in 8-12 weeks with a fixed price.
IRPR is a Python backend development firm that builds production-grade backends for SaaS, fintech, and healthcare platforms. We use Django, FastAPI, and Flask with PostgreSQL, Redis, and AWS.
Our fixed-price engagements run 8-12 weeks for an MVP, typically $80K-$250K depending on complexity. Every project includes CI/CD, automated testing, and HIPAA or PCI-DSS compliance where required.
Founders who need a scalable API before funding, CTOs migrating from a monolith to microservices, and product teams launching a new feature within 3 months hire us.

Why choose a dedicated Python backend development firm?
We bring proven patterns from 200+ shipped products.
IRPR has built Python backends for startups and enterprises across 50+ countries. Our team uses the same tools and practices that power high-traffic production systems.
Every project includes automated testing, CI/CD, and monitoring from day one. You get a backend that is ready for production, not a prototype that needs months of hardening.
The difference between IRPR and a generic dev shop
Not all Python developers deliver production-ready backends.
Many agencies focus on writing code and moving on. IRPR ships complete systems with automated builds, security scanning, and deployment playbooks.
Our engineers average 10+ years of experience. We follow strict coding standards and enforce code reviews on every pull request.

EdTech Learning Management Backend
Developed a scalable backend for an online learning platform using Django and WebSockets for live classes. Supported 20,000 concurrent users during peak hours.
Why teams hire us.
Fixed-price, not hourly
Every project gets a fixed quote after the Roadmap phase (week 2). No invoices change without a signed change order.
Senior engineers only
Our team consists of engineers with 10+ years average experience. We never outsource or use junior developers on client projects.
8-12 week MVPs
From concept to production in 8-12 weeks. This timeline means you launch before your competitors and start gathering real user feedback.
Production-ready by default
Every backend ships with CI/CD, automated testing, logging, and monitoring. You don't pay extra for essentials like Sentry or Datadog integration.
HIPAA and PCI-DSS compliance
We build backends that meet healthcare and financial compliance standards. Our infrastructure follows AWS Well-Architected Framework for security.
Full code ownership
You own all source code, Dockerfiles, Terraform scripts, and documentation. No licensing fees, no proprietary frameworks, no black boxes.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
