Professional Python App Development PartnerApp Development
Ship a Python backend in 12 weeks. Fixed price, full ownership, senior engineers only.
IRPR builds production Python apps for B2B and B2C companies. We use Django for MVPs, FastAPI for high-throughput APIs, Celery for async tasks, and AWS for infrastructure.
Every project ships in 8 to 12 weeks with a fixed price between $80K and $250K. We handle SOC 2, HIPAA, and PCI-DSS compliance from day one.
Startup CTOs hire us to validate ideas with a working MVP. Enterprise IT directors use us to migrate legacy PHP or Java apps to Python. Product managers bring us in to build data pipelines that replace manual Excel workflows.

What a Professional Python App Development Partner Delivers
IRPR ships Python apps that handle real traffic, real data, and real compliance requirements.
A Python app development partner does more than write code. They design the database schema, set up CI/CD pipelines, configure monitoring, and document the API. We ship source code to your GitHub repo from day one.
Every project includes a staging environment on AWS with auto-scaling, a production deployment with 99.9% uptime SLA, and Sentry error tracking. We use Terraform to manage infrastructure as code so you can clone the entire setup in another region.
Generic Dev Shop vs IRPR: the Real Difference
Most agencies stretch timelines and bill hourly. IRPR gives you a fixed price and a senior team.
When you hire a generic dev shop, you pay for junior developers who learn on your project. They use hourly billing, so scope changes mean surprise invoices. You get no ownership of the code until the final payment.
IRPR works differently. We assign senior Python engineers with 5+ years of experience. You get a fixed quote in week 2 of the Roadmap phase. The source code is yours from day one, and we deploy to your own AWS account.
- Junior engineers with 1-2 years experience
- Hourly billing with no cap
- Code stays on their servers until paid
- No compliance documentation
- Manual deploys with downtime
- You own nothing until final invoice
- Senior engineers with 5+ years Python
- Fixed price agreed in the Roadmap phase
- Source code in your GitHub repo from day one
- HIPAA, SOC 2, PCI-DSS compliance built in
- CI/CD with automated tests and zero-downtime deploys
- Full IP ownership, no licenses
How IRPR Builds Your Python App in 4 Phases
From idea to production in 12 weeks or less. Every phase has a clear deliverable and a fixed price.
The process starts with a 2-day Discovery Sprint where we map your user flows and define the database schema. Then we lock the scope and give you a fixed quote.
During the Build phase, we deliver working code every 2 weeks. You see the app on a live staging environment. The final Release phase includes load testing, security audit, and production deployment.
What Ships with Every Python App Project
You get more than code. These are the deliverables that make the project production-ready.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Staging environment on AWS ECS
- Production deployment with blue-green deploys
- Sentry error tracking and performance monitoring
- PostgreSQL database with automated backups
- OpenAPI 3.0 documentation for all endpoints
- Terraform scripts for infrastructure provisioning
- Load test report (k6 or Locust)
- Compliance checklist (HIPAA, SOC 2, or PCI-DSS)
What we ship in this practice.
Multi-Tenant SaaS Backend for a Fintech Startup
Built a Django backend with PostgreSQL and Stripe. Handles 50K active users, processes 200K transactions per month, and supports role-based access per tenant. Reduced time-to-bill from 3 days to 15 minutes.
HIPAA-Compliant Patient Data API
Developed a FastAPI service for a telemedicine company. Integrates with Epic EHR, encrypts all PHI at rest and in transit, and stores audit logs for 7 years. Cut API response time from 1.2s to 200ms.
Real-Time Inventory Optimization Engine
Created a Python microservice using Celery and Redis for an ecommerce brand. Calculates reorder points across 10 warehouses. Reduced stockouts by 40% and saved $200K in annual holding costs.
Data Pipeline for a Logistics Company
Built an Airflow DAG that ingests GPS data from 5K trucks, enriches it with weather APIs, and writes to Snowflake. Runs every 15 minutes with 99.5% uptime. Replaced a legacy SQL Server job that failed weekly.
AI-Powered Chatbot for Customer Support
Deployed a LangChain-based chatbot on AWS Lambda. Integrates with Zendesk and returns answers from a knowledge base of 2K articles. Handles 70% of tier-1 support tickets without human intervention.
Franchise Management Portal
Built a Django monolith for a restaurant chain. Manages menu updates, supplier orders, and staff schedules across 150 locations. Reduced manual data entry by 8 hours per week per location.
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 cost before we write a single line of code.
Senior engineers only
We don't hire juniors. Every Python engineer has 5+ years of experience and has shipped at least 10 production apps. You get a lead engineer who can architect the whole system.
8-12 week MVPs
We ship a working, deployable product in 8 to 12 weeks. Not a prototype or a mockup. A real app with authentication, database, API, and a staging environment you can test immediately.
Full IP ownership
You own everything we build. The source code, the infrastructure scripts, the documentation. No licenses, no royalties, no shared rights. We transfer all repos to you on day one.
Async-first collaboration
Our team works across 7 time zones. You communicate via Slack and Notion. We do daily standups in writing and weekly video demos. No 9-to-5 dependency, no travel costs.
Compliance-ready from day one
We build HIPAA, SOC 2, and PCI-DSS controls into the architecture from the first sprint. You get an audit-ready system without retrofitting. Already executed over 20 compliance projects.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
