Why IRPR is the Top Python App Development Partner
We deliver production-grade Python applications on time and on budget.
IRPR has shipped over 200 Python-based products for clients in 50+ countries. Our engineers have an average of 12 years of experience with Python, Django, FastAPI, and the broader ecosystem. Every project uses modern tooling like Docker, Kubernetes, and GitHub Actions.
We start with a 2-week Roadmap phase where we define the architecture, tech stack, and fixed price. After that, we build the MVP in 8-12 weeks. You own all code, and we set up CI/CD so you can keep iterating after we hand over the keys.
How We Differ from Other Python Dev Shops
Most agencies overpromise and underdeliver. IRPR gives you certainty.
We have a fixed-price model that prevents budget blowouts. Our 8-12 week sprint cadence means you see a working product in weeks, not months. All code is thoroughly tested with 90%+ coverage and deployed to cloud infra managed by us.
When you hire generic Python developers, you often get junior engineers with no production experience. IRPR only works with senior engineers who have shipped Python systems at scale. We give you a dedicated team that communicates daily via Slack or video calls.
- Hourly billing with no cap
- Juniors mixed with seniors
- No defined delivery timeline
- Code quality not guaranteed
- No CI/CD setup
- You own nothing but get a ZIP file
- Fixed price from day one
- Only senior Python engineers
- 8-12 week MVP guarantee
- Automated tests with 90%+ coverage
- CI/CD on GitHub Actions with staging and prod
- Full source code ownership with repo access
Our Python Development Process
From idea to production in four phases.
We follow a structured four-phase approach that has delivered 200+ successful projects. Each phase ends with a tangible deliverable so you can see progress in real time.
Phase one is the Idea validation and Roadmap. Phase two is building the MVP with weekly demos. Phase three is release and deployment. Phase four is a 30-day warranty period with optional ongoing support.
What Ships When You Hire IRPR
Every Python project comes with a complete set of deliverables.
We don't just give you code. You get an entire production infrastructure that your team can take over immediately.
All deliverables are documented and tested. We use Python best practices including type hints, linters, and security scanning.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions (test, build, deploy)
- Database schema and migration scripts
- Staging and production environments on AWS or GCP
- API documentation (OpenAPI/Swagger)
- Automated test suite with 90%+ coverage
- Sentry error tracking and logging setup
- Docker Compose or Kubernetes manifests
- Admin dashboard (Django Admin or custom UI)
- 30-day warranty with bug fixes

Why teams hire us.
Fixed price, not hourly
Every Python project gets a fixed quote during the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep. You know the cost before we write a line of code.
Senior engineers only, no juniors
IRPR only hires senior Python engineers with 10+ years of experience. Our team has built systems for NASA, top banks, and unicorn startups. You never get offshore juniors.
