Top FastAPI Development TeamDevelopment Team
We build production-grade FastAPIs with async endpoints and automatic OpenAPI docs. Get an MVP in 8-12 weeks with fixed pricing.
IRPR is a top FastAPI development team that builds async APIs, microservices, and full-stack applications using FastAPI, Pydantic v2, SQLAlchemy 2.0, and PostgreSQL. We write type-safe endpoints with automatic validation and OpenAPI schema generation.
Every project ships in 8-12 weeks with a fixed price range of $80K-$250K. We follow HIPAA, PCI-DSS, and SOC 2 compliance standards. Your API includes async workers via Celery, Redis caching, and Docker-based CI/CD pipelines.
Founders hire us to replace slow Django monoliths with FastAPI microservices. CTOs hire us to build real-time data pipelines for fintech and healthcare. Product managers hire us to create RESTful APIs that integrate with Stripe, Twilio, and OpenAI.

Why IRPR is a Top FastAPI Development Team
We have shipped 200+ products using FastAPI, with 98% on-time delivery and a 12-week average MVP timeline.
Our team has been building FastAPI backends since version 0.50. We use Pydantic v2 for strict data validation, SQLAlchemy 2.0 for async ORM, and Alembic for migrations. Every API includes automatic OpenAPI documentation at /docs.
We deploy on AWS ECS with Docker containers, auto-scaling, and CloudFront CDN. Our CI/CD pipeline runs tests on every push and deploys to staging automatically. We provide 99.9% uptime SLAs for production APIs.
The Difference Between a Generic Dev Shop and a Top FastAPI Team
Most agencies sell FastAPI but ship slow, untyped code. IRPR delivers production-grade APIs with async performance and full test coverage.
Generic shops often use synchronous code in FastAPI, defeating its async benefits. They skip type hints, write monolithic views, and ignore schema validation. That leads to runtime errors and poor performance under load.
IRPR writes fully async endpoints with Pydantic v2 validation, dependency injection for auth and database sessions, and unit tests with pytest-asyncio. Every endpoint is documented in OpenAPI and tested for 1000+ concurrent requests.
- Synchronous code in async endpoints
- No type hints or Pydantic schemas
- Monolithic API with no separation of concerns
- Zero automated tests
- Manual deployment without CI/CD
- No load testing before production
- 100% async endpoints with asyncio
- Strict Pydantic v2 validation
- Modular routers with dependency injection
- 90%+ test coverage with pytest-asyncio
- CI/CD with GitHub Actions and Docker
- Load tested for 1000+ concurrent requests
Our FastAPI Development Process
We follow a 4-phase process from idea to production API, with milestones at every step.
Each phase includes a review meeting with your team. We use Notion for task tracking, Slack for daily updates, and GitHub for code reviews. You see progress every week.
What Ships with Every FastAPI Project
You get a fully functional API with all the production essentials included in the fixed price.
We ship everything you need to run a production API. No hidden costs for deployment or testing. You own the code from day one.
- Source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- Docker Compose for local development
- Pydantic v2 schemas with validation
- JWT or OAuth2 authentication
- SQLAlchemy 2.0 async ORM with migrations
- Celery workers for background tasks
- Redis caching layer
- Sentry error tracking
- OpenAPI /docs endpoint
What we ship in this practice.
Fintech Payment Gateway API
Built a FastAPI gateway processing 500+ transactions per second with Stripe Connect integration. Reduced latency by 60% compared to the previous Django sync API. Tech stack: FastAPI, Celery, Redis, PostgreSQL, Stripe API.
Healthcare Patient Portal Backend
Developed a HIPAA-compliant FastAPI backend for a telemedicine startup. Handled 10,000 concurrent WebSocket connections for real-time video scheduling. Tech stack: FastAPI, WebSockets, SQLAlchemy, AWS ECS, HIPAA-compliant logging.
Ecommerce Order Processing Microservice
Created a FastAPI microservice for order fulfillment that processes 20,000 orders per hour. Integrated with Shopify and ShipStation via webhooks. Reduced order processing time from 15 minutes to 30 seconds. Tech stack: FastAPI, RabbitMQ, PostgreSQL, Shopify API.
SaaS Usage Metering API
Built a multi-tenant FastAPI backend that tracks API usage per customer and triggers Stripe billing events. Handles 1 million requests per day with 99.99% uptime. Tech stack: FastAPI, Redis, PostgreSQL, Stripe, Prometheus.
Real-Time Logistics Tracking API
Developed a FastAPI WebSocket service for live GPS tracking of 5,000 delivery vehicles. Updates every 2 seconds with sub-second latency. Tech stack: FastAPI, WebSockets, Redis Streams, PostgreSQL, Mapbox API.
AI Content Generation Backend
Created a FastAPI backend that orchestrates OpenAI API calls for automated blog post generation. Processes 1,000 requests per minute with async batching. Tech stack: FastAPI, Celery, OpenAI API, Pinecone vector DB, PostgreSQL.
Why teams hire us.
We wrote FastAPI since version 0.50
IRPR has been using FastAPI since its early releases. We contributed to open-source FastAPI libraries. Our team knows the framework internals, not just the docs.
Fixed price, not hourly
Every FastAPI project gets a fixed quote after the Roadmap phase in week 2. No hourly billing, no surprise invoices. You know the cost before we write a line of code.
Async by default, not an afterthought
We write every endpoint with async def and use async database drivers like asyncpg. Your API handles 10x more concurrent requests than a sync equivalent.
Full code ownership from day one
You own the entire codebase from the first commit. We push to your GitHub repo. No proprietary frameworks, no lock-in. You can take the code anywhere.
Production-ready in 8-12 weeks
We ship a deployable API with CI/CD, monitoring, and documentation in under 12 weeks. Our record is 8 weeks for a fintech API with 50 endpoints.
Compliance built in, not bolted on
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs from the start. For fintech, we handle PCI scope reduction. For healthcare, we encrypt PHI at rest and in transit.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
