Why choose a top Python app development agency?
Building a Python application in-house can cost 3x more and take 6 months longer. Our proven process gets you to market faster.
IRPR has shipped over 200 Python applications across 50 countries. Our senior engineers average 10+ years of Python experience, with deep expertise in Django (version 5.0), FastAPI (0.110), and Celery (5.3). We use PostgreSQL 16, Redis 7, and AWS ECS for production deployments.
Each project starts with a 2-week Roadmap phase where we define the architecture, database schema, API endpoints, and delivery timeline. We commit to a fixed price after that phase. No hourly billing, no scope creep. You own the code from day one.
How we differ from generic Python shops
Most Python agencies outsource to junior devs or work hourly. We do the opposite.
When you hire a generic Python development shop, you often get offshore junior developers, vague timelines, and code that breaks after deployment. They charge by the hour, so the budget balloons. They rarely set up CI/CD or monitoring.
IRPR works differently. Every project is staffed with 2-4 senior Python engineers based in the Americas and Europe. We use a fixed price based on a clear specification. We ship your code on GitHub with automated testing, error tracking via Sentry, and production monitoring with Datadog.
- Junior or outsourced devs
- Hourly billing with no cap
- No CI/CD pipeline setup
- No error tracking pre-configured
- Manual deployment that breaks
- You own nothing until final payment
- Senior Python engineers (10+ yr avg)
- Fixed price after Roadmap (week 2)
- GitHub Actions CI/CD from day 1
- Sentry error tracking and alerts
- AWS ECS or Docker Compose for staging
- Full code ownership upon kickoff
Our Python development process in 4 phases
We move from concept to production in 8-12 weeks using a structured four-step approach.
Phase 1: Idea Validation. In the first week, we review your product spec, user stories, and data sources. We identify the Python framework (Django vs FastAPI vs Flask) and the cloud provider (AWS, GCP, or Azure).
Phase 2: Roadmap. In week 2, we produce a detailed technical specification, database design, API contract, and a fixed-price proposal. You approve the roadmap before we write a single line of production code.
What ships with every Python project
Every project includes more than just code. You get a complete production infrastructure.
We treat each application as a product, not a one-off project. Our standard delivery includes CI/CD, error tracking, and infrastructure as code. No hidden setup work after delivery.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Sentry error monitoring with alerts
- Datadog or New Relic APM integration
- Docker Compose for local development
- Infrastructure as code (AWS CDK or Terraform)
- API documentation (Swagger/OpenAPI)
- 4 weeks of production support after launch
- Database migration scripts (Alembic or Django migrations)
- Load testing report using Locust or k6
What we ship in this practice.
Fintech payment reconciliation engine
Built a FastAPI backend that reconciles 50,000 transactions per hour from Stripe, PayPal, and bank files. Reduced manual reconciliation from 20 hours to 4 hours per week. Tech stack: FastAPI, PostgreSQL 16, Celery, Redis, Sentry.
HIPAA-compliant patient portal
Developed a Django web app with FHIR API integration for a telehealth startup. Handled 250 concurrent users with end-to-end encryption and full audit logs. Tech stack: Django 5.0, PostgreSQL, pgp encryption, AWS ECS.
Multi-tenant SaaS data dashboard
Created a Python backend using FastAPI and Metabase for embedded analytics. Supports 200 tenants with resource isolation. Reduced customer churn by 30% by providing real-time metrics. Tech stack: FastAPI, PostgreSQL, Redis, Metabase.
Real-time asset tracking platform
Built a Django Channels WebSocket server to stream GPS data from 1,000+ IoT devices. Dashboard updates every 2 seconds with sub-100ms latency. Tech stack: Django, Channels 4, Redis, PostgreSQL, AWS ECS.
Ecommerce recommendation API
Developed a FastAPI microservice that serves personalized product recommendations using collaborative filtering. Increased average order value by 18%. Tech stack: FastAPI, scikit-learn, PostgreSQL, Redis, Docker.
EdTech grade analytics platform
Built a Django backend that ingests quiz results from 50 schools daily and generates performance reports. Cut grade data processing time from 3 days to 2 hours. Tech stack: Django, Celery, PostgreSQL, AWS Lambda.
Why teams hire us.
Senior engineers only, no juniors
Every project team includes Python developers with at least 8 years of experience. We do not outsource to offshore junior shops. Your lead engineer has shipped multiple production Python apps.
Fixed price after Roadmap
We quote a fixed price in week 2 after the Roadmap phase. No hourly billing, no surprise invoices. Typical Python projects range from $80K to $250K depending on scope and compliance needs.
Full code ownership from day one
You own the GitHub repository from the first commit. There is no IP retention, no licensing fees. IRPR uses a standard work-for-hire agreement.
Production infrastructure included
Every project ships with CI/CD, error monitoring (Sentry), APM (Datadog), and infrastructure as code. Your team can run and maintain the app from launch day without IRPR.
8-12 week delivery guaranteed
We set a firm timeline in the Roadmap phase and hit it 98% of the time. If we are late, we add engineers at no extra cost until we catch up.
Compliance-ready by design
We build HIPAA, PCI-DSS, and SOC 2 compliant applications from the ground up. Our Python projects include encryption, audit trails, and role-based access control out of the box.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
