Python Backend Development PartnerDevelopment Partner
We build production-grade Python backends in 12 weeks. Fixed price, no surprises.
IRPR is a Python backend development partner that ships production systems using Django, FastAPI, Flask, PostgreSQL, Redis, Celery, and AWS. We build APIs, microservices, data pipelines, and real-time systems that handle millions of requests per day.
Every project starts with a 2-week Roadmap phase for a fixed price. Full builds run 8 to 12 weeks and cost $80,000 to $250,000 depending on scope. We comply with HIPAA, PCI-DSS, SOC 2, and FERPA for regulated industries.
CTOs hire us when their in-house team cannot scale fast enough. Startup founders hire us to ship their SaaS MVP in 12 weeks. Enterprise engineering directors hire us to build internal tools that replace legacy systems. We work async-first with daily overlap hours.

Why IRPR Is Your Python Backend Development Partner
We have built over 200 Python backends for clients in 50 countries. Here is what that experience delivers.
Every Python backend we ship includes automated testing with Pytest, continuous integration via GitHub Actions, and deployment to AWS ECS or Lambda. We use Sentry for error tracking and Datadog for monitoring. Code is stored in your private GitHub repository from day one.
Our team writes clean, typed Python code with MyPy and Black. We enforce pre-commit hooks and code review for every pull request. You get a system that is easy to maintain and scale after we hand it over.
How IRPR Differs From Other Python Agencies
Most Python shops bill hourly and scope creep kills your budget. We do not work that way.
We start every engagement with a 2-week Roadmap phase. You pay a fixed price of $8,000 to $15,000 for a detailed specification with wireframes, database schema, API endpoints, and a delivery timeline. After you approve the Roadmap, we quote the full build at a fixed price.
During the build you get a Slack channel with the engineering team, weekly video demos, and a real-time project board. No time tracking, no surprise invoices, no arguments about what is in scope.
- Hourly billing with no cap
- No written specification before build
- Junior developers on your project
- Unclear ownership of code and IP
- No monitoring or error tracking setup
- Handoff with no documentation
- Fixed price per phase and per build
- 2-week Roadmap with full spec
- Senior Python engineers with 10+ years experience
- You own all code and IP from day one
- Sentry, Datadog, and CI/CD included
- Complete technical documentation and handoff
Our Process: From Idea to Python Backend
We follow a four-phase process that de-risks your investment and delivers on time.
Phase 1 is the Idea phase where we align on goals, user stories, and technical constraints. This takes 1 week and costs $0. We sign an NDA and a simple master services agreement.
Phase 2 is the Roadmap phase where we deliver a detailed plan. Phase 3 is the Product build where we code, test, and deploy. Phase 4 is the Release where we hand over everything including source code, credentials, and runbooks.
What Ships With Every Python Backend
Every project includes these deliverables by default. No add-ons, no hidden fees.
We ship more than just code. You get a fully documented, monitored, and deployable system that your team can run independently. All tools and accounts are set up under your ownership.
- Source code in your private GitHub repository
- CI/CD pipeline with GitHub Actions and Pytest
- Dockerized application with docker-compose and Dockerfile
- API documentation with Swagger/OpenAPI
- Error tracking with Sentry
- Application monitoring with Datadog
- Database schema migration scripts (Alembic)
- Deployment runbook with environment variables
- Load testing results with Locust
- Technical handoff meeting with Q&A
