Leading Python App Development ServicesApp Development
We build Python apps for startups and enterprises. Ship production-ready web and AI apps in 8-12 weeks with fixed pricing.
IRPR builds Python applications for companies that need reliable, scalable software. We use Django for full-stack web apps, FastAPI for high-performance APIs, Flask for lightweight services, and Celery for background task processing. Our data layer runs on PostgreSQL and Redis, and we deploy everything on AWS or GCP with Docker and Kubernetes.
We ship production-ready Python apps in 8-12 weeks. Fixed pricing starts at $80,000 and goes up to $250,000 depending on complexity. Every project complies with HIPAA, PCI-DSS, or SOC 2 if required. You own the source code and all intellectual property from day one.
CTOs hire us to build their core product without hiring an internal team. Product managers use us to launch MVPs and validate ideas fast. Healthcare and fintech companies work with us because we understand regulatory compliance and deliver auditable code.

Why Choose IRPR for Python App Development
We have shipped over 200 Python applications for clients in 50 countries.
Our team of senior Python engineers averages 10+ years of experience. We use Django, FastAPI, and Flask daily and know the ecosystem inside out. Every project includes automated testing, CI/CD pipelines, and infrastructure as code.
We work async-first with overlap hours from 9 AM to 12 PM EST. This lets us hire the best talent globally while keeping communication fast. Clients get daily updates on Slack and a live project dashboard.
How IRPR Differs from Generic Python Shops
Most agencies bill hourly and disappear after launch. We do the opposite.
Generic dev shops often use junior developers, change requirements mid-project, and deliver code you cannot maintain. They charge by the hour and have no incentive to finish fast.
IRPR works with senior engineers only. We give you a fixed price after a 2-week Roadmap phase. You own all code, and we include a handover session so your team can take over.
- Junior developers with 1-2 years experience
- Hourly billing with no cap
- No compliance knowledge (HIPAA, PCI, SOC 2)
- Code delivered without tests or CI/CD
- No handover or documentation
- You do not own the code until final payment
- Senior engineers with 10+ years average experience
- Fixed price after Roadmap phase - no surprises
- Built-in compliance for HIPAA, PCI-DSS, SOC 2
- Full test suite, CI/CD on GitHub Actions, Sentry monitoring
- Handover session and architecture docs
- You own the code from day one
Our Python App Development Process
From idea to production in 4 phases, each with a clear deliverable.
We do not start coding on day one. The first 2 weeks are dedicated to understanding your business, defining scope, and creating a detailed Roadmap. You approve the Roadmap before we write a single line of code.
After the Roadmap, we build the product in 6-10 weeks depending on complexity. We ship the MVP with core features, then iterate based on user feedback. Every release includes deployment to your AWS or GCP account.
What Ships with Every Python Project
You get more than just code. Every project includes these deliverables by default.
We believe in shipping production-ready systems, not prototypes. Every Python app we build includes infrastructure, monitoring, and documentation so your team can maintain it.
All code is stored in your own GitHub repository. We set up CI/CD pipelines that run tests and deploy automatically. You get a live dashboard with error tracking and performance metrics.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions or GitLab CI
- Automated test suite with 80%+ coverage
- Sentry error tracking and performance monitoring
- Infrastructure as code (Terraform or Pulumi)
- Docker containers for local and production
- API documentation (OpenAPI/Swagger)
- Architecture decision records (ADRs)
- Security audit report (SAST + dependency scan)
- Handover session and 1 month of post-launch support
