Top FastAPI Development DevelopersFastAPI
We build production-grade FastAPI backends in 8-12 weeks. Fixed pricing, senior engineers, full code ownership.
IRPR builds high-performance backends using FastAPI, SQLAlchemy, Pydantic, and async Python. We create REST APIs, microservices, and real-time systems that handle thousands of requests per second.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We support HIPAA, PCI-DSS, and SOC 2 compliance. You get senior engineers, not juniors.
CTOs scaling their API infrastructure hire us. Startup founders building MVPs for funding rounds hire us. Enterprise teams migrating from Django or Flask to FastAPI hire us.
Types of software we ship.
REST API Development
Build scalable REST APIs with FastAPI, Pydantic validation, and PostgreSQL. Includes Swagger docs and auto-generated OpenAPI specs.
Microservices Architecture
Decompose monoliths into FastAPI microservices with RabbitMQ or Kafka. Use Docker and Kubernetes for orchestration.
Real-time Data Pipelines
Stream data with FastAPI and WebSockets. Integrate with Redis, Celery, and Apache Spark for low-latency processing.
API Gateway Implementation
Route, throttle, and authenticate APIs using FastAPI-based gateways. Integrate rate limiting with Redis and OAuth2.
Authentication System
Implement JWT, OAuth2, or SAML authentication with FastAPI. Includes role-based access control and session management.
File Processing API
Upload, transform, and serve images, PDFs, or CSV files with FastAPI. Use S3, Celery, and Pillow for processing.
WebSocket Server
Build real-time chat, notifications, or live dashboards with FastAPI WebSockets. Supports async broadcasting and room management.
GraphQL Hybrid API
Combine REST and GraphQL in one FastAPI server using Strawberry or Graphene. Resolve queries with SQLAlchemy and DataLoader.
We build for every business type.

What Top FastAPI Development Developers Deliver
Every FastAPI project from IRPR ships with a full production stack.
Our senior developers write clean async Python code using FastAPI, SQLAlchemy, and Pydantic. Every API includes automatic OpenAPI documentation, request validation, and error handling.
We deploy to AWS or GCP with Docker and Kubernetes. Each release goes through CI/CD pipelines with pytest, coverage reports, and Sentry error tracking.
IRPR vs Generic Development Shops
Hiring the top FastAPI development developers means choosing a partner that delivers on time and on budget.
Most agencies quote hourly rates and vague timelines. You end up with junior developers learning FastAPI on your dime.
IRPR assigns senior engineers who have shipped 200+ products. We give you a fixed quote after a 2-week Roadmap phase.
- Hourly billing with no cap
- Junior or offshore developers
- No compliance experience
- Vague delivery timelines
- You own nothing until paid extra
- Slow communication across time zones
- Fixed price from the start
- Senior FastAPI engineers only
- HIPAA, PCI, SOC 2 certified
- 8-12 week delivery guarantee
- Full code ownership day one
- Async-first with daily standups
Our FastAPI Development Process
Four phases take you from idea to a live FastAPI backend.
We start with a Discovery week to understand your data models and endpoints. Then we build a detailed Roadmap with fixed milestones.
The Build phase runs in 2-week sprints with daily commits. Deploy to staging after each sprint. Go live in week 8-12.
What Ships with Every FastAPI Backend
You get a production-ready API, not just code.
Every project includes everything needed to run and maintain the backend. No hidden extras.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions
- Automated tests with pytest (90%+ coverage)
- Docker Compose and Dockerfile for local dev
- Deployment scripts for AWS ECS or GCP Cloud Run
- Sentry error tracking and logging
- Swagger/OpenAPI documentation
- Database migrations with Alembic
- Postman collection for endpoint testing
- 1-hour post-launch support session
What we ship in this practice.
Fintech Payment Processing API
Built a FastAPI-based payment gateway processing 10,000 transactions per minute. Integrated Stripe, Plaid, and custom fraud scoring. Reduced transaction failure rate by 40%.
Healthcare Patient Scheduling API
Developed a HIPAA-compliant FastAPI backend for a telemedicine platform. Handles 5,000 appointments per day. Uses FHIR standards and encrypted data storage.
E-commerce Recommendation Engine
Created a real-time recommendation API using FastAPI and Redis. A/B testing improved conversion rate by 18%. Supports 1 million product SKUs.
SaaS Subscription Management API
Delivered a billing API with Stripe integration and usage metering. Manages 50,000 active subscriptions. Uses Celery for scheduled invoice generation.
Logistics Real-Time Tracking API
Built a FastAPI WebSocket server for live package tracking. Handles 2,000 concurrent connections. Integrates with GPS providers and warehouse systems.
Media Content Delivery API
Developed a FastAPI backend for video transcoding and CDN delivery. Processes 10 hours of video daily. Uses S3, FFmpeg, and CloudFront.
Why teams hire us.
Fixed price, not hourly
Every FastAPI project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
IRPR hires no juniors. Every developer has 10+ years of Python experience and has shipped at least 5 FastAPI projects in production.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. Our infrastructure includes encryption at rest and in transit, audit logs, and access controls.
Fast delivery guaranteed
We deliver a working FastAPI MVP in 8-12 weeks. 98% of our projects ship on time. We use sprint tracking and daily standups.
Full code ownership
You own every line of code from day one. No IP disputes, no licensing fees. We transfer the GitHub repo and CI/CD pipelines immediately.
Async-first communication
We communicate via Slack, Notion, and Linear. Overlap 4 hours daily with US time zones. No meetings for the sake of meetings.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
