We build production-grade FastAPI backends in 8-12 weeks. Fixed price, senior engineers, full ownership.
IRPR is a FastAPI development vendor that builds high-performance backends for startups and enterprises. We use FastAPI, Pydantic v2, SQLAlchemy 2.0, and async PostgreSQL to deliver APIs that handle thousands of requests per second.
Every project ships with a fixed price quote after a 2-week Roadmap phase. Typical MVPs take 8-12 weeks and cost $80K-$250K. We support compliance standards like HIPAA, PCI-DSS, and SOC 2.
Founders hire us when they need a production-ready API fast. CTOs hire us to replace slow Django or Flask backends. Product managers hire us to build internal tools with real-time data. Investors hire us to de-risk technical execution.
Stateless REST APIs with FastAPI, JWT auth, and OpenAPI docs auto-generated from Pydantic schemas.
Async data ingestion with FastAPI, Redis Streams, and Celery workers for ETL jobs.
API gateway built with FastAPI routing to multiple microservices, each deployed in Docker containers.
Real-time WebSocket endpoints using FastAPI's WebSocket support for chat, notifications, and live dashboards.
FastAPI backend for admin panels with role-based access control, audit logs, and CSV export.
FastAPI service that connects to Stripe, HubSpot, or Salesforce via async HTTP clients and webhooks.
Deploy ML models with FastAPI endpoints, ONNX runtime, and background task processing.
Async file upload and processing pipeline with FastAPI, S3, and background task workers.
We ship FastAPI backends that run in production from day one.
IRPR has delivered 200+ products using FastAPI, Python 3.12, and async PostgreSQL. Every API we build includes auto-generated OpenAPI docs, Pydantic validation, and unit tests with 90%+ coverage.
Our engineers average 8+ years of Python experience. We write async code that scales to thousands of concurrent requests without blocking. We deploy on AWS ECS or Railway with zero-downtime updates.
Not all vendors deliver production-grade FastAPI backends.
Many agencies claim FastAPI expertise but ship code that blocks on I/O, lacks type hints, or fails under load. They use hourly billing and change scope mid-project.
IRPR delivers fixed-price FastAPI projects with senior engineers. We write async code, enforce Pydantic validation, and deploy with CI/CD pipelines on GitHub Actions.
We follow a structured 4-phase process to deliver your backend.
Every project starts with a 2-week Roadmap phase where we define the API contract, database schema, and deployment architecture. You get a fixed price and timeline before we write a single line of code.
After the Roadmap, we build your FastAPI backend in 8-12 weeks. We ship in 2-week sprints with demos every Friday. You see working endpoints from week 1.
You get a production-ready backend, not just code.
IRPR delivers a complete backend system with everything needed to run in production. You own the code, the infrastructure, and the documentation from day one.
We include monitoring, error tracking, and performance dashboards so you can sleep through the night.
Built a FastAPI backend with async PostgreSQL and Redis caching. Handles 10,000+ requests per second with sub-50ms response times. Reduced server costs by 40% compared to the previous Django backend.
Developed a FastAPI service with Pydantic v2 for strict data validation and async endpoints for EHR integration. Passed HIPAA audit on first try. Shipped in 10 weeks.
Created a FastAPI microservice with WebSocket support for fraud detection alerts. Integrated with Stripe and Plaid. Processes $2M in transactions daily with 99.99% uptime.
Built a FastAPI backend with Elasticsearch for full-text search and Redis for caching. Handles 500,000 product queries per hour. Reduced page load time by 60%.
Delivered a FastAPI service with Celery workers for batch processing and WebSocket notifications for real-time updates. Automated 80% of manual data entry tasks. Saved 50 hours per week.
Deployed a FastAPI endpoint with ONNX runtime for property valuation predictions. Handles 1,000 concurrent requests with 200ms latency. Integrated with MLS data feeds.
Every engineer on your project has 8+ years of Python experience and has shipped FastAPI in production. We do not outsource to junior developers.
You get a fixed price quote after the Roadmap phase (week 2). No hourly billing, no scope creep, no surprise invoices. The price covers all endpoints, tests, and deployment.
Every FastAPI backend ships with auto-generated OpenAPI docs, Pydantic validation, async database queries, and CI/CD pipelines. You get a staging environment in week 2.
You own the source code, the Docker images, the CI/CD pipeline, and the deployment scripts. There is no lock-in, no license fees, no ongoing royalty.
We build FastAPI backends that meet HIPAA, PCI-DSS, and SOC 2 requirements. We implement encryption at rest, audit logging, and role-based access control.
We can kick off a new FastAPI project within 1-2 weeks of signing. Our async-first workflow means we can overlap with your team from day one.
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.
