Why IRPR is the top python backend development partner
Our clients come to us for speed, reliability, and compliance. Here is what we deliver on every project.
IRPR has shipped over 200 Python backends for clients in 50+ countries. We use a fixed-price model that starts with a 2-week Roadmap phase. During Roadmap, we define the architecture, API contracts, database schema, and deployment plan. You get a fixed quote before any development begins.
Our senior engineers average 10+ years of Python experience. Every project includes automated testing with Pytest, CI/CD with GitHub Actions, and monitoring with Sentry and Datadog. We guarantee 99.9% uptime for production systems.
How we differ from other python backend companies
Most development shops work hourly and change scope. We do the opposite.
Generic dev shops often start with a vague estimate and bill by the hour. They change the price when you add features. They hand you code with no tests, no CI/CD, and no documentation. They disappear after launch.
IRPR gives you a fixed price after Roadmap. We write tests from day one. We set up CI/CD on GitHub Actions, Sentry error tracking, and Datadog monitoring. We hand you full ownership of the code, the pipeline, and the infrastructure.
- Hourly billing with no cap
- No defined architecture upfront
- No automated tests
- No CI/CD pipeline
- No monitoring or alerting
- No post-launch support
- Fixed price after 2-week Roadmap
- Full architecture document before coding
- Pytest coverage at 90%+
- GitHub Actions CI/CD from day one
- Sentry + Datadog monitoring included
- 30-day post-launch warranty
Our process for building your python backend
We follow a 4-phase process that removes guesswork and delivers on time.
Every project starts with a discovery call where we understand your product, users, and compliance needs. Then we move into Roadmap, where we define the full architecture and give you a fixed price.
After Roadmap, our engineers build in 2-week sprints with demos every Friday. You see working code from week 3. The final phase is Release, where we deploy to production and hand over everything.
What ships with every python backend
Every project includes these deliverables by default. No hidden costs.
We believe in full transparency. Every deliverable is listed in the Roadmap document, and nothing is added later without your approval. Here is what ships on every project.
- Source code in your GitHub repository
- CI/CD pipeline with GitHub Actions
- Automated tests with Pytest (90%+ coverage)
- API documentation with Swagger or ReDoc
- Database schema migration scripts
- Docker Compose for local development
- Sentry error tracking integration
- Datadog monitoring dashboard
- Deployment playbook for AWS, GCP, or Azure
- 30-day post-launch support
What we ship in this practice.
SaaS billing backend

Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a single line of code.
Senior engineers only
Our team averages 10+ years of Python experience. Every engineer has shipped production systems at scale. No junior developers, no offshore outsourcing. You work directly with the people building your product.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant backends from day one. We use encryption at rest and in transit, audit logging, and role-based access control. No costly retrofitting later.
Full ownership
You own the source code, the CI/CD pipeline, the infrastructure, and the documentation. No licensing fees, no vendor lock-in. You can take the code to any team after launch.
8-12 week MVPs
We ship production-ready backends in 8-12 weeks. Our Roadmap phase eliminates guesswork, and 2-week sprints keep momentum high. You see working code from week 3.
Post-launch warranty
Every project includes 30 days of post-launch support. We fix bugs, handle deployments, and answer questions. After that, we offer ongoing maintenance at a fixed monthly rate.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
