We build production FastAPI APIs for startups and enterprises. Get a fixed-price quote in week 2 and ship in 8-12 weeks.
IRPR builds production-grade APIs using FastAPI, Python's fastest web framework. We use Pydantic for data validation, asyncio for concurrency, and SQLAlchemy for database access to ship secure, high-performance APIs that handle 10,000+ requests per second.
Every FastAPI project ships in 8-12 weeks with a fixed price between $80K and $250K. We include automated API documentation (Swagger/ReDoc), CI/CD pipelines, Docker containerization, and a full security audit. Compliance standards like SOC 2 and PCI-DSS are baked in from day one.
CTOs needing to scale their API layer hire us. Product teams requiring a fast MVP for a new SaaS idea hire us. Fintech and healthcare companies that need asynchronous, low-latency APIs with strict compliance hire us.
Build CRUD REST APIs with FastAPI, Pydantic schemas, and PostgreSQL. Includes auto-generated OpenAPI docs.
Implement a GraphQL gateway with Strawberry or Ariadne on top of FastAPI for flexible data queries.
Add real-time features using FastAPI WebSocket support with Redis Pub/Sub for chat, notifications, or live updates.
Break monolithic apps into async microservices using FastAPI, RabbitMQ, and Docker Swarm for independent scaling.
Create a central API gateway with FastAPI that routes, rate-limits, and authenticates requests to multiple backend services.
Offload heavy processing with Celery workers triggered by FastAPI endpoints. Handles 1000+ concurrent tasks.
Build ETL pipelines with FastAPI, Pandas, and PostgreSQL for real-time data ingestion and transformation.
Power mobile apps with a FastAPI backend optimized for battery life and low bandwidth using gzip compression and pagination.
FastAPI is 60% faster than Flask for async endpoints and scales to thousands of concurrent connections.
FastAPI leverages Python 3.10+ type hints and Pydantic for automatic request validation and serialization. This means your API docs are always in sync with code, and errors are caught at compile time not runtime.
IRPR has shipped over 200 FastAPI projects across 50 countries. Our clients see 40% less code compared to Flask and 2x faster development cycles due to built-in dependency injection and async support.
Most agencies treat FastAPI like any other framework. We treat it as the core of our async architecture.
Generic shops write synchronous code and call it FastAPI. They skip Pydantic best practices, ignore async patterns, and deliver APIs that block under load.
IRPR assigns senior Python engineers who have built production FastAPI apps for fintech, healthcare, and SaaS. We write pure asynchronous handlers, optimize query performance with SQLAlchemy 2.0, and include load testing in every contract.
We follow a four-phase process that guarantees on-time delivery and production-grade quality.
Every project starts with a two-week Roadmap phase where we define endpoints, data models, and infrastructure. You get a fixed price and a detailed timeline before any coding begins.
During the Build phase we work in two-week sprints with continuous demos. The final two weeks are dedicated to performance testing, security scanning, and deployment automation.
Every deliverable is production-ready with no loose ends.
When we finish a FastAPI project, you get a complete, deployable system. Nothing is left for you to figure out.
Built a PCI-DSS compliant payment gateway using FastAPI, Stripe Connect, and PostgreSQL. The API processes 10,000 transactions per second with sub-50ms latency. Reduced manual reconciliation from 4 hours to 10 minutes daily.
Developed a WebSocket-based chat API with FastAPI, Redis Pub/Sub, and PostgreSQL. Handles 50,000 concurrent connections with message delivery in under 100ms. Enabled real-time tutoring sessions for 2 million users.
Created a high-performance catalog API with FastAPI, Elasticsearch, and PostgreSQL. Supports 500,000 products with full-text search returning results in under 200ms. Increased product discovery by 35%.
Built a HIPAA-compliant FHIR R4 API with FastAPI, HAPI FHIR, and PostgreSQL. Processes 5 million patient records with full audit logging. Reduced integration time for partner hospitals from 6 months to 6 weeks.
Developed a real-time tracking API using FastAPI, WebSockets, and Redis. Handles 1 million GPS updates per day from delivery vehicles. Reduced delivery ETAs error from 15 minutes to under 2 minutes.
Built a multi-tenant API with FastAPI, SQLAlchemy row-level security, and Stripe subscription management. Supports 500+ tenants with data isolation. Enabled the client to launch their SaaS product in 10 weeks instead of 8 months.
Every FastAPI project gets a fixed quote after the Roadmap phase (week 2). You never see a surprise invoice. The price you see is the price you pay.
Our engineers have 8+ years of Python experience and have shipped FastAPI apps in production since version 0.1. We don't train juniors on your dime.
We write pure async handlers with asyncio and Uvicorn. Your API handles thousands of concurrent requests without blocking. No sync-to-async hacks.
Every endpoint gets automatic Swagger and ReDoc docs thanks to FastAPI and Pydantic. Your frontend team or external partners can start integrating immediately.
We design for failure with health checks, auto-scaling, and database replication. Our deployed FastAPI apps achieve 99.9% uptime as measured by third-party monitoring.
You own every line of code from day one. There is no licensing, no hidden subscriptions, no lock-in. The repository is yours to deploy, modify, or sell.
Every engagement runs through the same four-stage pipeline. Predictable by design.
30-minute discovery call. No deck. We'll tell you honestly what it takes, how long, and how much.
