Hire an Expert FastAPI Development TeamFastAPI
We build production-ready APIs and backends in 8 to 12 weeks. Fixed pricing from $80k with full code ownership.
IRPR is an expert FastAPI development team. We use FastAPI, SQLAlchemy, and Pydantic to build async APIs with automatic OpenAPI documentation.
We ship production-ready backends in 8 to 12 weeks with fixed pricing from $80k to $250k. Every project includes comprehensive test coverage and a CI/CD pipeline on GitHub Actions.
Startups hire us to build their core API before fundraise. CTOs hire us to replace legacy Django or Flask backends. Product managers hire us to ship a scalable microservice architecture for their SaaS.

Why hire an expert FastAPI development team?
We have delivered over 200 production FastAPI backends across multiple industries.
Our team uses FastAPI daily. We write async endpoints with SQLAlchemy and Redis for high performance and low latency.
We ship with auto-generated OpenAPI docs, pytest coverage at 90%+, and Docker containers. Every project includes CI/CD on GitHub Actions.
What sets IRPR apart from generic Python development shops?
Most shops start coding immediately. We start with a detailed roadmap.
Generic shops work hourly with no fixed scope. They often under-deliver on performance, security, and documentation.
IRPR delivers fixed price with a detailed roadmap. We use FastAPI best practices like async, caching, and middleware for production reliability.
- No FastAPI specialization
- Hourly billing with scope creep
- No formal roadmap
- Low test coverage
- No performance benchmarking
- No OpenAPI docs by default
- FastAPI specialists only
- Fixed price from roadmap
- Detailed roadmap delivered at week 2
- pytest coverage 90%+
- Load testing with Locust
- Auto-generated OpenAPI docs included
Our 4-step process for building FastAPI backends
From idea to deployed API in 12 weeks.
We follow a structured process that de-risks development and ensures quality at every stage.
Each phase includes clear deliverables and client approval gates before moving forward.
What ships with every FastAPI project?
Everything you need to run and maintain your API independently.
We hand over all source code, documentation, and deployment configs.
There are no black boxes or ongoing licensing fees.
- Source code in your private GitHub repo
- Auto-generated OpenAPI (Swagger) docs
- 100+ unit and integration tests with pytest
- CI/CD pipeline on GitHub Actions
- Docker Compose local development setup
- Production Docker images
- Database migrations with Alembic
- Sentry error tracking and logging
- Postman collection for API testing
- Deployment guide for AWS or Azure
What we ship in this practice.
Subscription Management API for a SaaS startup
We built a FastAPI backend with Stripe integration. The startup reduced billing errors by 95% and launched 6 weeks ahead of schedule. Tech stack: FastAPI, PostgreSQL, Stripe, Celery.
Real-time Dashboards for a Logistics Company
We built a FastAPI WebSocket server to stream tracking data to frontend dashboards. The client reduced data latency from 30 seconds to under 200 milliseconds. Tech stack: FastAPI, Redis, WebSockets, React.
AI Chatbot Backend for a Healthcare Platform
We deployed a FastAPI serving Hugging Face models for patient query classification. The platform handles 10,000 requests per hour with sub-second response times. Tech stack: FastAPI, Hugging Face, PostgreSQL, AWS SageMaker.
Order Processing API for an E-commerce Retailer
We built a FastAPI order system with Celery for async fulfillment and Stripe payments. The retailer processed $2M in monthly transactions without errors. Tech stack: FastAPI, Celery, Stripe, Redis.
Data Ingestion Pipeline for a Fintech Company
We created a FastAPI-based data pipeline ingesting 1 million events per day with Kafka. The team reduced data processing time by 80%. Tech stack: FastAPI, Kafka, MongoDB, Docker.
Authentication Microservice for a Multi-tenant SaaS
We built a scalable OAuth2 server with FastAPI, handling 50,000 users and 200 tenants. The client eliminated login failures entirely. Tech stack: FastAPI, OAuth2, JWT, PostgreSQL, Redis.
Why teams hire us.
Fixed price, not hourly
Every FastAPI project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
FastAPI specialists only
Our engineers work exclusively with FastAPI and Python async. We have shipped 200+ production APIs using this framework.
Production-ready from day one
We include OpenAPI docs, pytest coverage, CI/CD, and Docker in every project. Your API is deployable immediately after the final sprint.
Full code ownership
You own the entire codebase and IP. We hand over source code, docs, and deployment configs with no licensing restrictions.
8-12 week delivery guarantee
Our fixed-scope roadmaps ensure we deliver on time. 98% of our projects launch within the agreed timeline.
Built for scale
We design APIs with async, caching, and database optimization from the start. Our systems handle 10,000+ requests per second without refactoring.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
