Our FastAPI development process
We follow a 4-phase process that eliminates surprises.
Every project starts with a 2-week Discovery phase where we map your requirements and validate assumptions. Then we move to Roadmap for a fixed-price quote.
Development runs in 2-week sprints with daily standups and demos. Finally, we deploy to production and hand over everything.
What ships with every FastAPI project
You get more than just code. Every delivery includes these essentials.
IRPR believes in full transparency. When we finish, you own everything and can run it yourself.
We also provide documentation and training so your team knows how to maintain and extend the system.
- Source code in your GitHub or GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Docker containers for local and production
- Auto-generated OpenAPI documentation
- Unit tests with pytest (90%+ coverage)
- Deployment scripts for AWS/GCP
- Sentry error tracking and Datadog monitoring
- Postman collection for API testing
- 12 months of bug fixes and support
