Python App Development FirmDevelopment Firm
We build production-ready Python applications in 8-12 weeks. Fixed price, senior engineers, full code ownership.
IRPR is a Python app development firm that ships custom applications with Django, FastAPI, and PostgreSQL. We build everything from REST APIs and microservices to data pipelines and machine learning backends.
Every Python project ships with a Roadmap in week 2, a working MVP in 8-12 weeks, and full source code in your repository. Pricing ranges from $80,000 to $250,000 depending on scope. We work under HIPAA, PCI-DSS, SOC 2, and FERPA compliance.
We build Python apps for healthcare startups needing HIPAA-compliant patient portals, fintech companies requiring PCI-DSS payment APIs, SaaS businesses launching SOC 2-ready platforms, and ecommerce brands building custom recommendation engines.
Types of software we ship.
Python Web Application

Why hire a Python app development firm
IRPR has shipped over 200 Python applications across industries. Here are real numbers from our projects.
Our Python apps handle 50,000+ requests per second in production. We use FastAPI with async workers and PostgreSQL read replicas to maintain sub-10ms response times.
Every project achieves 99.9% uptime through multi-region deployment, automated failover, and 24/7 monitoring with Datadog and PagerDuty.
Python development firm vs generic agency
Most agencies hand your project to juniors. IRPR assigns senior engineers from day one.
A generic agency often starts with a vague estimate and expands scope mid-project. They use offshore teams with little Python depth.
IRPR locks the scope and price after a 2-week Roadmap phase. Our team averages 12 years of Python experience. We ship working code every sprint.
- hourly billing with no cap
- junior developers on your project
- no dedicated project manager
- unclear compliance coverage
- code delivered without tests
- no deployment or monitoring setup
- fixed price from Roadmap phase
- senior Python engineers only
- dedicated PM with weekly demos
- HIPAA, PCI, SOC 2, FERPA ready
- 95%+ test coverage by default
- CI/CD + Sentry + Datadog included
Our Python app development process
From idea to production in 8-12 weeks. Four phases, fixed timeline, no surprises.
Phase 1 (Idea - week 1) validates your concept with user research and technical feasibility. We create a product brief with clear acceptance criteria.
Phase 2 (Roadmap - week 2) produces a detailed scope document, wireframes, and a fixed-price contract. You get a line-item budget before we write any code.
What ships with your Python application
Every project includes everything you need to run and maintain the app yourself from day one.
We never leave you with a zip file. You get a production-ready system with CI/CD, monitoring, and documentation.
Our standard handoff includes automated tests, deployment scripts, and a runbook so your team can take over immediately.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions
- Dockerized application with docker-compose
- Database migrations with Alembic
- 95%+ automated test coverage (pytest)
- Sentry error tracking and Datadog monitoring
- Postman or OpenAPI documentation for all endpoints
- Deployment scripts for AWS / GCP / Azure
- Security audit report (OWASP Top 10)
- Admin panel with Django Admin or custom UI
What we ship in this practice.
Telehealth Patient Portal
Built a HIPAA-compliant Python app with Django and PostgreSQL for a mental health startup. The portal handles 15,000 patient appointments per month and reduced scheduling time by 60%. Deployed on AWS with Sentry and Datadog.
Payment Processing API
Designed a PCI-DSS compliant FastAPI backend for a fintech company. The API processes 500 transactions per second with sub-200ms latency. Integrated with Stripe, Plaid, and a custom fraud detection model.
Ecommerce Recommendation Engine
Created a Python microservice using FastAPI and Redis to serve personalized product recommendations. The engine increased average order value by 18% and handles 2 million requests daily.
SaaS Analytics Dashboard
Built a multi-tenant analytics platform with Django and TimescaleDB. The application ingests 10 million events per day and renders real-time dashboards using Chart.js. Achieved SOC 2 compliance in the first release.
Logistics Route Optimizer
Developed a Python API using FastAPI and OR-Tools for a logistics company. The optimizer reduces fuel costs by 22% and calculates optimal routes for 500+ delivery points in under 5 seconds.
Clinical Trial Data Pipeline
Implemented an ETL pipeline with Apache Airflow and Python to process clinical trial data for a research hospital. The pipeline reduced manual data entry by 80 hours per week and ensured GCP compliance.
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. 98% of our projects finish on budget.
Senior engineers only
Our team averages 12 years of Python experience. Every engineer has shipped at least 5 production applications. We never outsource or use junior developers.
8-12 week MVPs
From kickoff to production-ready MVP in 8-12 weeks. We ship working code every week with demos. Average time to first release is 9 weeks across 200+ projects.
Full code ownership
You own every line of code from day one. Source code lives in your GitHub repo. No proprietary frameworks, no license fees, no lock-in.
Compliance built in
We design for HIPAA, PCI-DSS, SOC 2, and FERPA from the start. Our standard pipeline includes encryption, access controls, and audit logging.
Post-launch support included
Every project ships with 30 days of warranty support. We also offer monthly retainer plans for scaling, feature additions, and 24/7 incident response.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
