Premium FastAPI Development TeamFastAPI
We build high-performance APIs with FastAPI and async Python. 200+ products shipped in 50+ countries with fixed pricing.
IRPR uses FastAPI for high-performance REST and GraphQL APIs, paired with Pydantic for validation, SQLAlchemy for database access, and async task queues with Celery.
We deliver production-ready APIs, CI/CD pipelines, and documentation in 8-12 weeks. Project costs range from $80K to $250K depending on complexity. All work meets HIPAA, PCI-DSS, or SOC 2 compliance as needed.
Our buyers include CTOs at SaaS startups needing a scalable backend in weeks, healthcare founders requiring HIPAA-compliant patient data APIs, fintech companies needing PCI-DSS level data handling, and ecommerce brands integrating real-time inventory.
Types of software we ship.
REST API Backend
Scalable API for web and mobile apps using FastAPI and PostgreSQL. Designed for high concurrency.
Microservices Gateway
Entry point API for multiple microservices. Uses FastAPI with Nginx and service discovery.
Real-time Data Pipeline
Async API for streaming data using FastAPI WebSockets and Kafka. Handles thousands of events per second.
Ecommerce Checkout API
Handles orders and payments with FastAPI and Stripe integration. Includes idempotency and fraud checks.
AI Model Inference API
Serves ML predictions via FastAPI endpoints. Uses TensorFlow or PyTorch with GPU support.

Proven Results with FastAPI
Our premium FastAPI development team ships production APIs that perform under load.
Every FastAPI project at IRPR starts with a clear roadmap and ends with a deployed, documented API. We reuse battle-tested components to cut development time without cutting quality.
Our team has shipped over 200 products across 50 countries. 98% of our FastAPI projects deliver on time and within budget.
The IRPR Difference for FastAPI Projects
Generic dev shops waste time and budget. IRPR delivers fixed-price FastAPI backends on schedule.
Many agencies bill hourly and drag out discovery. They lack deep FastAPI expertise and compliance knowledge. That leads to scope creep and delayed launches.
IRPR is different. We quote fixed prices after a 1-week Roadmap phase. Our engineers have shipped 50+ FastAPI systems for healthcare, fintech, and ecommerce. We already have the components, so you get a working API faster.
- Vague hourly billing
- Long discovery phase
- No compliance expertise
- Rebuilding from scratch
- No post-launch support
- Predictable delays
- Fixed price from Roadmap phase
- 12-week delivery target
- HIPAA/PCI/SOC 2 experienced
- Component library reuse
- SLA support
- 98% on-time delivery
How We Build Your FastAPI Project
Our process delivers a production-ready API in 8-12 weeks.
From discovery to deployment, each phase has a clear output. You know exactly what you get and when.
We use Lean principles and short feedback loops. Changes are easy because we show you a working API early.
