Professional Python App Development ServicesPython App
We ship production-grade Python applications in 8 to 12 weeks. Fixed pricing from $80K, senior engineers only.
IRPR builds custom Python applications for startups, scale-ups, and enterprises. We use Django for data-heavy web apps, FastAPI for high-throughput services, and Flask for lightweight microservices. Every project ships with PostgreSQL, Redis, and an automated CI/CD pipeline on GitHub Actions.
A typical Python project takes 12 to 14 weeks from roadmap to release. Pricing is fixed and starts at $80K, going up to $250K for complex systems. We deliver for HIPAA, PCI-DSS, and SOC 2 environments.
We work with CTOs launching a new SaaS product, founders building an MVP to raise seed funding, product managers migrating a legacy system to Python, and engineering leads who need a senior team for a fixed-budget project.

What a professional Python app development team delivers
Here is what we ship for every Python project at IRPR.
We build the application end to end. You get a fully functional Python app with a modern frontend (React or Next.js), a database schema, authentication, and an admin panel. All code is your property from day one.
Every project includes automated tests, a CI/CD pipeline using GitHub Actions, staging and production environments on AWS or GCP, and Sentry error tracking. We also configure monitoring with Datadog or New Relic so you see real time metrics.
Why generic dev shops fail at Python projects
Most Python development teams cut corners. Here is the difference when you work with IRPR.
Generic shops assign junior developers who learn on your dime. They write untested code, skip CI/CD, and use shared hosting. When something breaks, you wait a week for a fix.
IRPR assigns senior engineers with 7+ years of Python experience. Every project has a dedicated tech lead. We write tests for every endpoint, set up monitoring from week one, and deploy on infrastructure that scales.
- Junior developers learning on your project
- No automated tests or CI/CD pipeline
- Shared hosting with no SLA
- Hourly billing with scope creep
- No documentation or handover plan
- Code ownership unclear
- Senior engineers with 7+ years Python experience
- 100% test coverage and automated CI/CD on GitHub Actions
- Production on AWS ECS with 99.9% uptime SLA
- Fixed price from $80K with no scope creep
- Full documentation and 30 day warranty
- You own all code and IP
Our process for building your Python application
We follow a four phase framework to deliver your Python app on time and on budget.
The process starts with a two week roadmap phase. We map out the database schema, API endpoints, user flows, and deployment architecture. You get a fixed price quote based on that roadmap.
Then we build the product in eight to ten weeks. We deploy to staging after each sprint, and you review working code every two weeks. Finally we release to production with a full runbook and monitoring.
What ships with your Python application
Every project from IRPR includes these deliverables by default.
We do not charge extra for basics like monitoring or documentation. Everything below is part of the fixed price.
- Full source code in your repository
- PostgreSQL database schema with migrations
- REST or GraphQL API with autogenerated docs
- CI/CD pipeline on GitHub Actions
- Staging and production environments on AWS ECS
- Sentry error tracking and Datadog monitoring
- 100% test coverage for all critical paths
- Admin panel built with Django Admin or custom React UI
- Authentication and authorization (JWT or OAuth2)
- 30 day post release warranty
What we ship in this practice.
Fintech dashboard for a payment processing startup
Built a real time dashboard using FastAPI and WebSockets. Processed 10,000 transactions per minute. Reduced the client's reporting latency from 4 hours to 30 seconds. Tech stack: FastAPI, PostgreSQL, Redis, Stripe, AWS.
HIPAA compliant telemedicine platform
Developed a Django based telemedicine app with Twilio Video and EHR integration. Passed HIPAA audit on first submission. Handles 500 concurrent video sessions daily. Tech stack: Django, Twilio, PostgreSQL, AWS, HIPAA compliance.
Multitenant SaaS for property management
Built a multitenant backend using Django Tenant Schemas and Stripe billing. Onboarded 50 property management firms in the first quarter. Tech stack: Django, PostgreSQL, Redis, Stripe, GCP.
ETL pipeline for a logistics company
Created an Apache Airflow data pipeline that ingests 2 million tracking events daily from 15 carriers. Reduced manual data entry by 80 hours per week. Tech stack: Airflow, PySpark, S3, Redshift, Datadog.
Content recommendation engine for a media site
Built a Python based recommendation engine using collaborative filtering and embeddings. Increased click through rate by 34% within two months. Tech stack: FastAPI, PostgreSQL, Redis, AWS SageMaker.
Fraud detection system for an ecommerce brand
Developed a real time fraud detection service using random forests and XGBoost. Blocked $1.2M in fraudulent transactions in the first six months. Tech stack: FastAPI, PostgreSQL, Scikit Learn, AWS Lambda.
Why teams hire us.
Fixed price, not hourly
Every Python 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 before we write a single line of code.
Senior engineers only
We do not have junior developers. Every engineer on your project has 7+ years of Python experience. We have shipped over 200 products across 50 countries.
8 to 12 week delivery
A typical Python MVP ships in 8 to 12 weeks. We have a 98% on time delivery rate. If we are late, the next sprint is free.
Full compliance support
We build Python applications for HIPAA, PCI-DSS, and SOC 2 environments. Our team has passed over 40 compliance audits. We include encryption, audit logs, and access controls by default.
You own everything
All source code, database schemas, configs, and documentation are your property. We do not use proprietary frameworks. You can take the code and run it anywhere.
30 day warranty
After production release, we fix any bugs at no extra cost for 30 days. We also provide a runbook and walkthrough for your engineering team.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
