Leading FastAPI Development ServicesDevelopment Services
We build high-performance APIs with FastAPI. Ship production-ready Python backends in 8-12 weeks.
IRPR builds high-performance APIs with FastAPI, using Pydantic for validation, SQLAlchemy for ORM, and async PostgreSQL for data persistence. We design REST, WebSocket, and GraphQL backends that handle thousands of concurrent requests with sub-50ms latency.
Every FastAPI project ships in 8-12 weeks with fixed pricing from $80K to $250K. We build HIPAA-compliant, SOC 2-ready, and PCI-DSS compliant APIs from day one. Our team has delivered over 200 products across 50+ countries with a 98% on-time record.
CTOs scaling backend infrastructure hire us for production-grade APIs. Product managers need fast MVPs to validate ideas. Enterprise architects migrate legacy systems to async Python. Startups building data-intensive applications rely on our FastAPI expertise.

FastAPI Development by the Numbers
Our FastAPI projects deliver measurable results.
IRPR has shipped over 200 products using FastAPI across fintech, healthcare, and SaaS. Each project is built with async Python, Pydantic, and PostgreSQL for maximum performance.
Our APIs handle thousands of concurrent requests with 99.9% uptime. We deploy with CI/CD, monitoring, and load testing built in. Clients see 40% faster time-to-market compared to traditional frameworks.
Why IRPR for FastAPI Development
Generic dev shops slow you down. IRPR ships fast.
Most agencies bill hourly and lack deep async Python expertise. They deliver generic templates that break under load and fail compliance audits.
IRPR builds production-ready FastAPI backends with fixed pricing, compliance baked in, and full ownership. We have delivered for fintech, healthcare, and SaaS clients across 50+ countries.
- Hourly billing, no fixed price
- Slow async expertise
- No compliance knowledge
- Generic templates
- Poor documentation
- No post-launch support
- Fixed price from day one
- Deep FastAPI & async Python
- Built-in HIPAA, SOC 2, PCI
- Custom architecture for scale
- CI/CD & monitoring included
- Dedicated support after launch
Our FastAPI Development Process
From idea to production in 8-12 weeks.
We start with a two-week Roadmap phase where we define endpoints, data models, and compliance requirements. You get a fixed quote and timeline.
Then we build in two-week sprints. By week 4 you have a working staging environment. By week 8 the API is production-ready with monitoring and documentation.
What Ships with Every FastAPI Project
Every deliverable is production-ready.
You get more than code. Every FastAPI project includes documentation, CI/CD, monitoring, and load testing results. No surprises.
- Source code in your GitHub repo
- FastAPI application with Pydantic schemas
- Async PostgreSQL database with Alembic migrations
- Authentication (JWT/OAuth2)
- API documentation (Swagger/ReDoc)
- CI/CD pipeline (GitHub Actions)
- Docker containerization
- Sentry error tracking
- Load testing results
- Postman collection
What we ship in this practice.
