Expert Python App Development DevelopersPython App
We hire and manage senior Python engineers who ship production code. 200+ apps delivered in 8-12 weeks with fixed pricing.
IRPR builds custom Python applications using Django, FastAPI, and Flask. Our team writes code that scales from MVP to 100k users without rewrites.
We deliver production-ready apps in 12 to 14 weeks with a fixed price of $80K to $250K. Every project includes HIPAA, PCI-DSS, or SOC 2 compliance if needed.
Startup founders hire us to validate their idea with a real Python MVP. CTOs at mid-market companies outsource core backend development. Product managers at enterprise teams engage us for brownfield rewrites of legacy Python systems.

Why Expert Python Developers Ship Faster at IRPR
Our senior Python engineers follow a repeatable process that eliminates rewrites.
IRPR only hires engineers with 5+ years of production Python experience. They have shipped Django and FastAPI projects for companies handling 50,000 requests per second. We test every commit with pytest and deploy through GitHub Actions into AWS ECS with zero-downtime upgrades.
Our Roadmap phase in week 2 locks the scope and the price. After that we sprint in 2-week cycles and push to staging every Friday. Clients see working code by week 4, not slide decks.
Generic Dev Shop vs IRPR: Python Development Reality
Most Python agencies patch together code. IRPR engineers write clean, production-ready systems from day one.
We have seen clients waste 16 weeks with offshore teams that delivered 2,000 lines of spaghetti code. That code had no tests, no type hints, and crashed under 100 concurrent users. The rewrite cost 3x the original budget.
IRPR starts with a technical spec in week 1, a Roadmap contract by week 2, and fully tested code in your repo by week 4. We use Black formatter, mypy type checks, and pre-commit hooks enforced on every PR.
- No Python type hints or static analysis
- Tests start in month 3 if at all
- No CI/CD until staging breaks
- Weekly status calls but no code demos
- No compliance handling (HIPAA, PCI)
- Hourly billing with scope creep
- mypy and Pylint enforced pre-commit
- 100% pytest coverage from week 1
- GitHub Actions CI/CD on day 1 of build
- Live staging environment by week 3
- HIPAA/PCI/SOC 2 built in from spec
- Fixed price locked in Roadmap phase
How We Build Your Python App in 12 Weeks
Four phases from idea to deployment, each with a concrete deliverable.
Our kickoff starts with a 3-day technical workshop. We map your data model, API endpoints, and auth flow. By day 5 you have a shared Notion spec and a demo schedule.
Engineering runs in 2-week sprints with daily standups and Friday demos. We deploy to a staging URL that you can test from your phone. Load testing happens before week 10.
What Ships with Every Python App
You get production infrastructure, not just source code.
Every project includes a fully configured cloud environment on AWS or GCP. We set up auto-scaling, Postgres replication, and Redis caching. No manual server login required.
Documentation is part of our process. You get a README with architecture diagrams (Mermaid), API docs (Swagger), and a runbook for common operations. The codebase uses pre-commit, CI checks, and semantic versioning.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Staging URL with SSL certificate
- PostgreSQL database with automated backups
- Sentry error tracking and alerting
- Swagger/OpenAPI documentation
- Docker containers for local development
- Load test report (Locust or k6)
- One-year code warranty (bugs fixed free)
- Training session for your team
What we ship in this practice.
HIPAA-Compliant Telemedicine Backend

Why teams hire us.
Senior engineers only, no juniors
Every engineer at IRPR has at least 6 years of Python production experience. We do not staff juniors or outsource to body shops. Our team averages 10 years of backend engineering.
Fixed price agreed in week 2
After the Roadmap phase you know the exact cost. No hourly billing, no surprises. 95% of our projects hit the original budget. Scope changes are priced separately before work begins.
Code ownership from day 1
You get full read-write access to a private GitHub repo on the first day of the build phase. All code, documentation, and infrastructure as code belongs to you. No licensing traps.
Compliance built in, not bolted on
We have shipped HIPAA apps (BAAs in place), PCI-DSS level 1 gateways, and SOC 2 type II backends. Our team knows the controls and implements them from the first commit, not at the end.
One year warranty on all code
If a bug appears in production within 12 months of release, we fix it at no cost. This covers 99% of edge cases that slip through QA. We stand behind our work with real support.
We ship every 2 weeks, not monthly
Each sprint ends with a deployed increment on a live staging URL. You see working features every 14 days, not slide decks or PDFs. Feedback loops are short and concrete.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
