Leading Python App Development ConsultantsPython App
We build custom Python applications with a fixed price and a 12-week delivery. 200+ products shipped across 50+ countries.
IRPR is a team of senior engineers who specialize in Python application development. We use Python with Django, FastAPI, Flask, Celery, PostgreSQL, and AWS Lambda to build web apps, APIs, data pipelines, and AI-powered products.
Every project starts with a fixed-price Roadmap phase in week 2. You get a clear scope with a delivery timeline of 8-12 weeks and a price range of $80K-$250K. All code is HIPAA, PCI-DSS, and SOC 2 compliant when required.
Founders hire us when they need a production-grade MVP for a SaaS platform. CTOs hire us to rebuild a legacy Python backend. Product managers hire us to build a custom analytics dashboard. Investors hire us to build their technical asset.

Why hire leading Python app development consultants
Most Python projects fail because of scope creep, slow delivery, and lack of senior talent.
IRPR has shipped 200+ Python applications in 8-12 weeks. Our consultants have 10+ years of experience each. We use a fixed-price model so you know the cost before a single line of code is written. Every project includes automated testing on GitHub Actions, Sentry error monitoring, and Datadog performance tracking.
We work with Python 3.12, Django 5.0, FastAPI 0.109, and deploy on AWS with Terraform. Our team has built systems processing 1M+ records per day for healthcare, fintech, and SaaS clients. We maintain a 98% on-time delivery rate.
Custom development vs. the big consultancies
Big consultancies charge hourly and have no fixed scope. IRPR does the opposite.
We have seen clients pay $300K+ to Accenture or Tata for a Python project that never shipped. Their model is hourly billing with rotating junior developers. You get no ownership, no transparency, and no timeline guarantee.
IRPR assigns 2-3 senior engineers to every project. We deliver a working application in 12 weeks or less. You own the source code, the domain, and the deploy pipeline. No hidden fees, no junior staff, no excuses.
- Hourly billing with no cap
- Junior developers doing the work
- No compliance documentation
- Custom CMS or boilerplate code
- Code stays with the shop
- No CI/CD or monitoring setup
- Fixed price after Roadmap phase
- Senior engineers only, avg 10+ years
- HIPAA, PCI-DSS, SOC 2 ready
- Django/FastAPI with modern stack
- Full IP ownership in your repo
- CI/CD on GitHub Actions, Sentry, Datadog
Our Python development process
From idea to production in 4 phases, each with a fixed cost and clear deliverables.
Phase 1 is the Roadmap. In week 2, we deliver a full plan with user stories, architecture diagrams, API contracts, and a fixed price. This costs $8K-$15K and is the blueprint for the entire project.
Phases 2-4 are Product, Release, and Growth. Each phase builds on the previous one. We ship a deployable application at the end of Product. Release adds monitoring, load testing, and documentation. Growth adds features and optimization.
What ships with your Python app
Every project includes production-ready infrastructure, not just code.
Most agencies hand you a zip file and disappear. We ship a complete system that you can run, monitor, and scale. The source code is in your GitHub repository from day one. The CI/CD pipeline runs on GitHub Actions with automated tests and deployment to AWS ECS.
We include Sentry for error tracking, Datadog for performance monitoring, and Terraform for infrastructure as code. The database schema includes migration scripts with Alembic. API documentation is auto-generated with OpenAPI. You get all of this in the fixed price.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with auto-deploy
- Dockerized application with docker-compose
- Terraform scripts for AWS infrastructure
- Sentry error tracking and alerting
- Datadog dashboards for performance and uptime
- API documentation via OpenAPI/Swagger
- Database migration scripts with Alembic
- Load testing results with Locust
- Security audit report and compliance docs
What we ship in this practice.
Custom SaaS platform for B2B analytics
We built a Django-based SaaS platform that ingests 500K events per day from client APIs. The system uses Celery for async processing, PostgreSQL for storage, and Stripe for billing. The client reduced manual reporting by 15 hours per week.
HIPAA-compliant API for telemedicine
We developed a FastAPI backend for a telehealth startup. The API handles real-time video scheduling, patient records, and payments. We achieved HIPAA compliance with encryption at rest and in transit. The client onboarded 200 providers in 3 months.
Real-time fraud detection pipeline
We deployed a Python pipeline using Apache Kafka and FastAPI to process 10K transactions per minute. The system flags suspicious activity with a Random Forest model. The client cut fraud losses by 40% in the first quarter.
Headless ecommerce backend for retail
We built a Django-based headless commerce platform with Elasticsearch for product search and Stripe for checkout. The backend handles 500K SKUs with real-time inventory sync. The client saw a 25% increase in conversion rate.
Content platform with AI recommendations
We created a FastAPI backend for a media company that serves 2M users per month. The system uses a LangChain-based recommendation engine to suggest articles. The client increased average session time by 3 minutes.
Data integration platform for logistics
We built a Python application using Apache Airflow and PostgreSQL to aggregate data from 50+ carrier APIs. The platform generates real-time shipment tracking and delivery ETAs. The client reduced integration time from 6 weeks to 2 days.
Why teams hire us.
Fixed price, not hourly billing
Every project gets a fixed quote after the Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the total cost in week 2.
Senior engineers only
Our team averages 10+ years of Python experience. No junior developers. Every engineer has shipped at least 5 production applications. You get the best, not the cheapest.
12-week delivery guarantee
We ship a working application in 8-12 weeks. We have a 98% on-time delivery rate. If we miss the deadline, we work for free until it ships.
Full code ownership
The source code is in your GitHub repository from day one. You own everything: code, domain, data, infrastructure config. No licenses, no lock-in, no surprises.
Built for compliance from day one
We design for HIPAA, PCI-DSS, and SOC 2 from the first line of code. Encryption, audit logs, access controls are built in. No retrofitting after launch.
Production-grade infrastructure included
Every project ships with CI/CD, monitoring, error tracking, and load testing. You get a system that is ready for 10K users on day one, not a prototype.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
