Why top python backend development agency IRPR delivers
We have shipped 200+ python backends for clients in 50+ countries.
Every python backend we build goes through our 4-phase framework: Idea, Roadmap, Product, Release. In the Roadmap phase (week 2), we deliver a detailed technical spec with architecture diagrams, API endpoints, and database schema. You approve the spec before we write a single line of code.
Our senior python engineers average 10+ years of experience. We use Django for data-heavy apps, FastAPI for high-performance APIs, and Flask for lightweight services. Every project includes automated tests with pytest, CI/CD with GitHub Actions, and monitoring with Sentry and Datadog.
The difference between a generic dev shop and IRPR
Most agencies bill hourly and change scope mid-project. IRPR does not.
Generic dev shops often assign junior developers who learn on your dime. They use outdated frameworks and skip testing. You pay for their learning curve and end up with technical debt.
IRPR assigns senior python engineers who have built backends for healthcare, fintech, and ecommerce clients. We write tests first, use modern tooling, and deliver on time. Every project has a fixed price from week 2.
- Junior developers with 2-3 years experience
- Hourly billing with no cap
- No written spec before coding
- Uses outdated Django 2.x or Flask 0.x
- No CI/CD or automated testing
- Scope creep charges every month
- Senior engineers with 10+ years experience
- Fixed price from week 2
- Detailed spec with API docs and schema
- Uses Django 5.x, FastAPI, or Flask 3.x
- CI/CD with GitHub Actions, pytest, Sentry
- No scope creep. Changes go through change order.
How IRPR builds your python backend in 4 phases
We follow a repeatable 4-phase framework that de-risks your investment.
Phase 1: Idea. We map your requirements in 3-5 discovery calls. You share your vision, we ask the hard questions about data models, API endpoints, and third-party integrations.
Phase 2: Roadmap. We deliver a technical spec with architecture diagrams, database schema, API endpoint list, and a fixed price quote. This takes 1-2 weeks and costs $5K-$10K.
What ships with every python backend from IRPR
Every project includes these deliverables by default.
We believe in full transparency. You own everything we build. No black boxes, no proprietary frameworks, no hidden fees.
Your team gets the same code, tools, and documentation we use internally. You can take over development anytime.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with pytest
- Docker Compose setup for local development
- API documentation with Swagger or OpenAPI
- Database schema migration scripts (Alembic)
- Sentry error tracking and Datadog monitoring
- Production deployment on AWS or GCP
- SSL certificate and domain configuration
- 30-day post-launch warranty and support
- Technical handover document and architecture diagram

We do not hire junior developers. Every engineer on your project has 10+ years of python experience and has shipped production backends for healthcare, fintech, or ecommerce clients.
HIPAA and PCI-DSS compliance built in
We build compliance into the architecture from day one. Encryption at rest (AES-256), encryption in transit (TLS 1.3), audit logging, and access controls. No afterthoughts.
