What You Get When You Hire IRPR as Your Expert Python Backend Development Company
Every engagement starts with a fixed price and a clear timeline so you can plan your product launch without surprises.
In the Roadmap phase (week 2), we produce a detailed technical specification with API endpoints, database schema, and deployment architecture. You get a fixed quote before any code is written. No hourly billing, no scope creep. We ship with 3 years of production support included.
Our engineers have built backend systems for companies processing over 1 million API requests per day. We use PostgreSQL for data, Redis for caching, and Docker for containerization. Every project includes a staging environment and automated CI/CD via GitHub Actions.
How IRPR Differs from Other Python Backend Development Agencies
Most agencies bill hourly and expand scope. IRPR delivers fixed price, fixed time, with senior engineers only.
We do not staff juniors or offshore teams. Every engineer has 7+ years of Python experience and has shipped production backends. You speak directly with the team building your system.
We use a two-week Roadmap phase to define every endpoint, data model, and integration before coding starts. This eliminates change orders and budget overruns. If the spec changes, we adjust the quote upfront.
- Hourly billing with no budget cap
- Junior developers with limited Python experience
- Vague specifications that lead to scope creep
- No dedicated project manager or QA
- Generic boilerplate code without your business logic
- Code ownership often unclear
- Fixed price agreed in week 2
- Senior Python engineers with 7+ years experience
- Detailed API spec and DB schema signed off before build
- Dedicated PM and automated test suite
- Custom business logic with full unit and integration tests
- You own 100% of the source code
Our 4-Phase Python Backend Development Process
We use a repeatable process that reduces risk and ensures on-time, on-budget delivery.
Every project follows the same four phases. The first two phases cost you nothing until you approve the fixed price quote.
We have shipped 200+ products using this process across 50 countries. It works for startups building their first MVP and for enterprises migrating legacy systems.
What Ships with Every Python Backend Project
You get more than just code. Every deliverable is production-ready from day one.
We do not hand over a zip file with instructions to 'figure it out.' Everything is documented, tested, and deployed on your infrastructure.
Your team can take over maintenance immediately because the codebase follows PEP 8 standards, includes in-line docs, and has a full test suite.
- Full Python source code in your GitHub repo
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error and performance monitoring
- Production Docker containers and docker-compose files
- API documentation via Swagger/OpenAPI
- Database migration scripts (Alembic)
- Load testing results with Locust
- Deployment runbook with environment variables and secrets
