We build high-performance APIs with FastAPI and Python. Your MVP ships in 8-12 weeks with a fixed price.
IRPR builds FastAPI applications for startups and enterprises. We use Python 3.12, async SQLAlchemy, Pydantic v2, and PostgreSQL to create APIs that handle 10,000+ requests per second with sub-50ms latency.
Every FastAPI project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle deployment on AWS ECS with auto-scaling, Sentry error tracking, and 99.9% uptime SLA. Our code passes PCI-DSS and HIPAA compliance audits.
We work with CTOs who need a scalable backend, product managers launching a new SaaS, founders building an MVP for investor demos, and engineering leads migrating from Django or Flask to FastAPI for better async performance.
Build RESTful APIs with FastAPI, OpenAPI docs, and JWT auth. Supports 10,000+ concurrent users.
Implement GraphQL endpoints using Strawberry or Ariadne with FastAPI. Subscriptions for real-time data.
Design event-driven microservices with FastAPI, RabbitMQ, and Docker Compose. Independent deploy units.
Stream processing with FastAPI WebSockets, Kafka, and Redis. Handles 1M+ events per day.
OAuth 2.0, OpenID Connect, RBAC with FastAPI. Integrates with Auth0, Okta, or custom JWT.
High-throughput ingestion APIs using FastAPI background tasks and Celery. Processes CSV, JSON, Parquet.
FastAPI backend for admin panels with SQLAdmin, audit logs, and role-based permissions.
Cart, checkout, inventory APIs with FastAPI and Stripe. Handles 500+ transactions per minute.
We have shipped over 200 products using FastAPI for clients in 50 countries.
FastAPI is the fastest growing Python web framework. It uses async IO to handle 10,000+ requests per second. Pydantic v2 ensures data validation with zero overhead. Our developers have written over 500,000 lines of FastAPI code across 40+ projects.
Every project starts with a 2-week Roadmap phase where we define the API schema, endpoints, and deployment architecture. You get a fixed price and timeline before any code is written. No surprises.
Most agencies treat FastAPI like Flask. We build it for scale from day one.
Generic shops write synchronous code in FastAPI, missing the async advantage. They skip automated API documentation and ignore deployment hardening. Their projects often need a rewrite within 6 months.
IRPR builds FastAPI applications with async SQLAlchemy, Pydantic v2 models, and auto-generated OpenAPI docs. We deploy on AWS ECS with CI/CD, Sentry monitoring, and database migration scripts. Your API is production-ready from the first commit.
A 4-phase process that delivers a production-ready API in 8-12 weeks.
Phase 1 is the Roadmap: we define every API endpoint, data model, and integration. You get a detailed specification and a fixed price. Phase 2 is development: we build the API in 2-week sprints with daily updates.
Phase 3 is testing and hardening: load testing with Locust, security audit, and documentation. Phase 4 is deployment: we set up staging and production environments, CI/CD pipelines, and monitoring. You own the code and infrastructure.
Every project includes these deliverables by default.
You get a production-ready FastAPI application with full async support, auto-generated OpenAPI documentation, and a CI/CD pipeline. The code is in your GitHub repository from day one.
We include database migrations, environment configuration, logging, error tracking, and deployment scripts. No black boxes. You can extend the API yourself or hand it to another team.

Developed a FastAPI API for a telehealth startup. Implemented OAuth 2.0 with Auth0, end-to-end encryption, and audit logging. Passed HIPAA audit on first submission. Tech stack: FastAPI, PostgreSQL, Auth0, AWS KMS.
Created a PCI-DSS compliant FastAPI API for a fintech company. Integrated with Stripe Connect for marketplace payments. Handled 10,000 transactions per day with 99.99% uptime. Tech stack: FastAPI, Stripe, PostgreSQL, Redis.
Built a FastAPI backend for a B2B marketplace with 500+ vendors. Implemented inventory sync, order routing, and real-time tracking. Reduced order processing time from 4 hours to 2 minutes. Tech stack: FastAPI, PostgreSQL, RabbitMQ, Stripe.
Developed a FastAPI ingestion API for a manufacturing client. Processed 1 million sensor readings per day with Kafka and InfluxDB. Provided real-time dashboards with Grafana. Tech stack: FastAPI, Kafka, InfluxDB, Grafana.
Built a FastAPI backend for an edtech platform serving 100,000 students. Implemented course enrollment, progress tracking, and certificate generation. Integrated with Stripe for payments. Tech stack: FastAPI, PostgreSQL, Redis, Stripe.
Every FastAPI developer at IRPR has 8+ years of Python experience. We have built APIs for companies handling $1B+ in transactions. No junior developers, no outsourcing.
After the 2-week Roadmap phase, you get a fixed price for the entire project. No hourly billing, no surprise invoices. If we discover new requirements, we add them to a separate quote.
We deploy to a staging environment in the first sprint. You get a working API with CI/CD, monitoring, and documentation. No long wait for deployment at the end.
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs. Our FastAPI projects include audit logs, encryption at rest, and role-based access control. We have passed 10+ compliance audits.
You own all source code, documentation, and infrastructure from day one. There is no lock-in. You can deploy anywhere, hire other teams, or extend the API yourself.
We can start your FastAPI project within 1-2 weeks of signing. We work async with daily overlap hours for US and European time zones. No waiting for resource availability.
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.
