We build production-ready backends with FastAPI in 8-12 weeks. Fixed price, no surprises.
IRPR builds high-performance backends using FastAPI, Python 3.12, Pydantic v2, SQLAlchemy, and async PostgreSQL. We use FastAPI for its automatic OpenAPI docs, async support, and type safety. Every endpoint is validated at compile time.
A typical FastAPI backend ships in 8-12 weeks with a fixed price of $80K-$250K. You get a fully documented API, CI/CD pipeline on GitHub Actions, Sentry error tracking, and 99.9% uptime SLA. We handle compliance like HIPAA, PCI-DSS, and SOC 2.
CTOs hire us when they need a scalable backend fast. Startup founders want an MVP in 10 weeks. Product managers need a team that writes tests and documents APIs. Enterprise architects want Python-native services that integrate with existing systems.
CRUD endpoints, authentication, rate limiting, and OpenAPI docs. Built with FastAPI, JWT, and PostgreSQL. Ships with Postman collection.
Event-driven services with RabbitMQ or Kafka. Each service runs in its own Docker container. Deployed on AWS ECS or Kubernetes.
WebSocket endpoints for live dashboards, chat, or notifications. Uses FastAPI's WebSocket support and Redis pub/sub.
Multi-tenant architecture with row-level security. Stripe integration for billing. Celery for background tasks like email and reports.
Serve TensorFlow or PyTorch models via REST endpoints. Async inference with Redis caching. Logs to CloudWatch.
Cart, payment, and order endpoints. Integrates with Stripe, PayPal, and Shopify. PCI-DSS compliant out of the box.
HIPAA-compliant FHIR endpoints. Encrypted at rest and in transit. Audit logs for every request. Integrates with Epic and Cerner.
Admin dashboards, reporting APIs, and data export endpoints. Connects to existing databases. Built with FastAPI and SQLAlchemy.
FastAPI is the fastest growing Python web framework for building APIs. It handles async, validation, and documentation automatically.
FastAPI uses Python type hints to generate OpenAPI docs and validate requests. No more writing separate schema files. The framework runs on Starlette and Uvicorn, handling 10,000+ requests per second. Pydantic v2 compiles models to Rust for even faster validation.
IRPR has shipped 30+ FastAPI backends across healthcare, fintech, and SaaS. We use async SQLAlchemy for database access, Redis for caching, and Celery for background jobs. Every project includes automated tests with pytest and 90%+ code coverage.
Most agencies bill hourly and deliver late. IRPR gives you a fixed price and a working API in 10 weeks.
Generic dev shops often over-promise on FastAPI experience. They write synchronous code, skip tests, and deliver spaghetti endpoints. Their APIs break under load and have no documentation.
IRPR writes async FastAPI from day one. Every endpoint has type validation, unit tests, and auto-generated docs. We deploy on Docker with health checks and auto-scaling. Your API is production-ready from week 1.
Our process takes you from idea to deployed API in 8-12 weeks. No scope creep, no delays.
The Roadmap phase (week 1-2) defines every endpoint, data model, and integration. You get a fixed price quote and a Gantt chart. No surprises.
The Product phase (weeks 3-10) builds the API in 2-week sprints. You see working endpoints every sprint. We deploy to staging after each sprint for your review.
You own everything. Source code, tests, docs, and infrastructure as code.
Every FastAPI project includes a private GitHub repo with full commit history. We write tests for every endpoint. You get a Postman collection and a README with setup instructions.
Your API is deployed on AWS ECS or Railway with auto-scaling. We set up Sentry for error tracking, CloudWatch for logs, and Datadog for performance monitoring. You get a Grafana dashboard showing request rates and latencies.
Built a HIPAA-compliant FastAPI backend for video consultations. Handles patient intake, appointment scheduling, and payment. Reduced onboarding time from 2 weeks to 3 days. Tech stack: FastAPI, PostgreSQL, Twilio Video, Stripe.
Developed a multi-tenant FastAPI API with role-based access. Integrated Stripe billing and Zendesk CRM. Scaled to 10,000 users in the first month. Tech stack: FastAPI, PostgreSQL, Redis, Stripe.
Built WebSocket endpoints for live viewer counts and engagement metrics. Reduced data latency from 5 minutes to under 1 second. Tech stack: FastAPI, WebSockets, Redis, ClickHouse.
Created a PCI-DSS compliant FastAPI backend for card payments and refunds. Handles 500 transactions per second with 99.99% uptime. Tech stack: FastAPI, PostgreSQL, Stripe, AWS KMS.
Developed a cart and checkout API that syncs with Shopify. Reduced abandoned carts by 15% with faster response times. Tech stack: FastAPI, PostgreSQL, Shopify API, Stripe.
Built a FastAPI service that serves a PyTorch model for route optimization. Each prediction takes under 50ms. Reduced delivery costs by 12%. Tech stack: FastAPI, PyTorch, Redis, Docker.
Every FastAPI project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices. You know the cost before we write a single line of code.
We write async FastAPI endpoints using async def and await. Your API handles thousands of concurrent connections without blocking. No synchronous code, no thread pool hacks.
Every endpoint has unit tests with pytest and 90%+ coverage. OpenAPI docs auto-generate from type hints. You get a Postman collection and a Swagger UI out of the box.
We deploy your API to a staging environment after the first sprint. You see working endpoints, real database queries, and live logs. No waiting until the end to see the product.
We build HIPAA, PCI-DSS, and SOC 2 compliant FastAPI backends. Encryption at rest and in transit. Audit logs for every request. Role-based access control by default.
All source code, tests, and infrastructure config are in your GitHub repo. Full ownership. No licensing fees. You can take the code and run it anywhere.
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.
