Senior Python App Development ConsultantsPython App
We ship production Python apps in 8-12 weeks. Fixed price, senior engineers only, no junior padding.
IRPR is a team of senior Python app development consultants. We build web apps, APIs, data pipelines, and AI chatbots using Python 3.13, FastAPI, Django, Celery, and PostgreSQL. Every project is staffed with engineers who have 10+ years of Python experience.
Your MVP ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for healthcare (HIPAA), finance (PCI-DSS), and SaaS (SOC 2). Code is fully owned by you from day one.
We work with CTOs at Series A startups who need a production-ready Python backend in 10 weeks. We help product managers at mid-market companies migrate from legacy PHP or Java to Python. We advise founders building AI-powered SaaS products who need a senior architect to design the system.

Why hire senior Python app development consultants
Most Python agencies staff juniors and bill hourly. IRPR gives you senior engineers at a fixed price with a guaranteed timeline.
Our consultants have an average of 12 years of Python experience. They have built production systems for healthcare, fintech, and SaaS companies across 50 countries. Every engineer can design a system architecture, write tests, deploy to AWS, and debug production issues without escalation.
We do not use junior developers or offshore teams. Your project gets 2-3 senior engineers who work in US time zone overlap hours. The same engineers stay with the project from Roadmap to Release.
Generic dev shop vs senior Python consultants
The difference between a generic dev shop and IRPR is the difference between code that ships and code that scales.
Generic dev shops assign junior developers to keep costs low. They use hourly billing so you never know the final price. They skip testing, skip documentation, and hand over code that breaks in production.
IRPR assigns senior engineers only. We give you a fixed price in week 2 during the Roadmap phase. We write automated tests, CI/CD pipelines, and production monitoring. Your code is deployed and running before we hand it over.
- Junior or mid-level developers
- Hourly billing with no cap
- No automated tests
- No CI/CD pipeline
- No production monitoring
- Code ownership is unclear
- Senior engineers only (12 yr avg)
- Fixed price from Roadmap phase
- 95%+ test coverage
- GitHub Actions CI/CD
- Sentry + Datadog monitoring
- Full code ownership from day one
Our process for Python app development consulting
We follow a four-phase process that de-risks your project from idea to production.
Every engagement starts with a 2-week Roadmap phase. We analyze your requirements, design the system architecture, and give you a fixed price and timeline. If you do not like the plan, you pay only for the Roadmap and walk away.
After you approve the Roadmap, we build the MVP in 8-12 weeks. We deploy to staging in week 4, run user testing in week 6, and ship to production by week 10. The Release phase includes a 30-day warranty with bug fixes and performance tuning.
What ships with your Python app
Every project includes production-ready infrastructure, not just source code.
We ship more than a GitHub repository. Your project includes a fully automated CI/CD pipeline, infrastructure-as-code for AWS, and production monitoring. You can deploy a new version with a single git push.
Documentation is included. You get API docs via Swagger/ReDoc, a README with setup instructions, and an architecture diagram. Your team can take over maintenance immediately.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with test and deploy stages
- Infrastructure-as-code using Terraform or AWS CDK
- PostgreSQL database with migration scripts using Alembic
- Sentry error tracking and Datadog APM monitoring
- Swagger/ReDoc API documentation
- Docker containers for local development
- Architecture diagram (Draw.io format)
- README with setup, deploy, and runbook instructions
- 30-day warranty with priority Slack support
What we ship in this practice.

Why teams hire us.
Senior engineers only, no juniors
Every engineer on your project has 10+ years of Python experience. We do not staff juniors or offshore teams. You get 2-3 senior consultants who design, build, and deploy your system.
Fixed price from week 2
After the 2-week Roadmap phase, you get a fixed price for the entire project. No hourly billing, no surprise invoices, no scope creep charges. The price covers the full MVP build.
8-12 week MVP timeline
Your production-ready MVP ships in 8-12 weeks. We deploy a staging environment in week 4 so you can test and give feedback early. 98% of our projects deliver on time.
Full code ownership
You own every line of code from day one. We put the source code in your private GitHub repo and transfer all AWS infrastructure to your account. No licensing fees, no ongoing royalties.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliance into the architecture from the start. Our healthcare apps pass audits on the first try. We encrypt data at rest and in transit by default.
Production monitoring included
We set up Sentry error tracking, Datadog APM, and CloudWatch alarms before we hand over the project. You get alerts when something breaks and dashboards to monitor performance.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
