Affordable FastAPI Development ServicesFastAPI Development
Build high-performance APIs in 8-12 weeks. Fixed pricing from $80K.
IRPR builds affordable FastAPI development services using async Python, Pydantic, SQLAlchemy, and PostgreSQL. We create high-performance APIs that scale from prototype to production with zero downtime.
Every project ships with a fixed price from $80K to $250K, delivered in 8-12 weeks. We embed HIPAA, SOC 2, and PCI-DSS compliance into the architecture. You get source code, CI/CD pipelines, and monitoring from day one.
CTOs at SaaS startups hire us to build scalable API backends. Fintech founders need PCI-compliant payment gateways. Healthcare product managers require HIPAA-compliant patient data APIs. We serve all three with senior engineers only.

Why FastAPI for your next project
FastAPI delivers speed and reliability.
FastAPI is the fastest Python web framework for building APIs. It automatically generates OpenAPI documentation and validates requests with Pydantic. IRPR has shipped 200+ FastAPI projects with zero production incidents.
Our clients choose FastAPI for its async performance and built-in compliance support. We combine it with PostgreSQL, Redis, and AWS to handle 10,000+ requests per second.
Generic dev shop vs IRPR
Not all agencies deliver the same quality.
Many agencies start projects without a fixed price or clear timeline. They bill hourly, change scope mid-project, and hand off code with no documentation. IRPR operates differently.
We give you a fixed price and timeline in week 2. Our senior engineers build with compliance built-in. You own everything from day one.
- No fixed pricing
- Hourly billing surprises
- No dedicated project manager
- Slow async communication
- No compliance expertise
- Code ownership unclear
- Fixed price from Roadmap phase
- No hourly billing
- Dedicated PM with daily standups
- Async-first with US overlap hours
- HIPAA/SOC2/PCI-DSS built-in
- Full code ownership on day 1
How we build your FastAPI backend
A structured process from idea to deployment.
We follow a four-phase process that de-risks your investment. Each phase has clear deliverables and milestones. You see progress every two weeks.
No black boxes. You review code, test endpoints, and approve features. By week 12, you have a production-ready API.
