Why FastAPI for your API backend
FastAPI is built for speed and reliability.
IRPR uses FastAPI because it delivers up to 300% faster performance than Flask or Django REST. Automatic OpenAPI documentation and Pydantic validation reduce integration bugs.
Our team has shipped over 200 FastAPI-based APIs. Each one includes CI/CD pipelines, Docker containers, and monitoring out of the box.
Generic Python shop vs IRPR
Not all FastAPI developers deliver the same.
Many development shops use junior talent and bill hourly. That creates budget overruns and quality problems.
IRPR only hires senior engineers with 10+ years experience. We give you a fixed price at week 2 and ship in 8-12 weeks.
- Hourly billing with no cap
- No fixed scope
- Junior developers on your project
- No compliance expertise
- Delayed timelines
- No ownership of code
- Fixed price from Roadmap
- Senior engineers only
- HIPAA/PCI/SOC2 ready
- 8-12 week delivery
- Source code ownership
- CI/CD and monitoring included
