Why businesses choose leading Python app development developers
IRPR delivers Python applications that scale from day one.
We have shipped 200+ Python-based products across 50 countries. Our engineers average at least 8 years of experience. Every project uses a dedicated team of senior Python developers who write production-grade code with tests, documentation, and monitoring.
Our fixed price model means you know the budget before build starts. The Roadmap phase (week 2) locks scope, timeline, and cost. No hourly billing, no surprise invoices. 98% of our projects ship on time.
The difference between generic dev shops and IRPR
Not all Python development teams deliver the same results.
Generic shops often use junior developers, vague timelines, and hourly billing. They deliver incomplete code with no tests or documentation. You don't know what you'll get or when.
IRPR assigns senior engineers only, writes tests from day one, and ships source code with full documentation. We guarantee 8-12 week delivery with fixed pricing and no scope creep.
- Junior or offshore developers handling your project
- Vague estimates that often double
- Hourly billing with no cap
- Zero testing or CI/CD pipeline
- Code ownership is unclear
- Response times measured in days
- Senior engineers only (8+ years average experience)
- Fixed price locked in week 2 after Roadmap
- No hourly billing - one budget, no surprises
- Full CI/CD pipeline with automated tests
- 100% code ownership - source in your repo
- Real-time Slack communication, response in minutes
How IRPR builds your Python app in 4 phases
Our process takes you from idea to deployed product in 8-12 weeks.
We start with a discovery call to understand your requirements. Then we produce a detailed Roadmap with architecture, user stories, and fixed price. Build happens in 2-week sprints with daily standups and a staging environment. Release includes deployment, monitoring, and documentation.
Every phase has clear deliverables and gates. You see progress in real time. No black box development.
What you receive when the project ships
Every Python app comes with a complete delivery package.
We don't just hand you code. You get a production-ready system with monitoring, CI/CD, and documentation. Your team can take over immediately or hire us for ongoing maintenance.
All deliverables are standard across every project. Nothing is extra or optional.
- Source code in your private GitHub or GitLab repo
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error tracking and performance monitoring
- Deployment scripts for AWS, GCP, or Azure
- API documentation (OpenAPI/Swagger)
- Database schema and migration scripts
- Administrator and user guides
- Load testing results (k6 or Locust)
- Post-launch support for 30 days
- Fixed price contract with no hidden fees
What we ship in this practice.
Real-Time Analytics Dashboard for Logistics

Multi-Tenant SaaS Ecommerce Platform
Built a Django-based multi-tenant platform for 20+ retail brands. Shared database with row-level permissions. Features include inventory management, order sync, and Shopify integration via GraphQL.
Automated ETL Pipeline for Media Company
Designed an Airflow pipeline that ingests 2 TB of daily log data from CDN servers. Transforms with PySpark and loads into Snowflake. Reduced manual data processing by 30 hours per week.
Chatbot Backend for Customer Support
Implemented a Python chatbot using Rasa framework. Integrated with Zendesk and Slack. Handles 60% of tier-1 support tickets without human intervention. Average response time under 2 seconds.
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 exact budget before we write a single line of code.
Senior Engineers Only
Our developers average 8+ years of production Python experience. No junior or offshore teams. Each engineer has shipped at least 10 production applications using Django, FastAPI, or Flask.
HIPAA & PCI-DSS Compliant
We build applications that pass strict compliance audits. Our healthcare apps use encrypted databases, audit logs, and signed BAAs. Fintech apps handle card data with tokenization and vaulting.
8-12 Week Delivery
From kickoff to production in 8-12 weeks for most MVPs. We use proven frameworks and templates to accelerate development without sacrificing code quality.
Full Code Ownership
You own 100% of the source code from day one. It lives in your repository. No proprietary frameworks or lock-in. You can take the project anywhere after delivery.
Post-Launch Support Included
Every project includes 30 days of post-launch support. We fix bugs, handle deployments, and provide knowledge transfer to your team. Extended support available at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
