Build production-ready APIs with FastAPI and Python 3.12. Get a fixed-price MVP delivered in 12 weeks.
IRPR builds premium FastAPI development services for clients who need high-performance, async-capable APIs. We use FastAPI with Pydantic, SQLAlchemy, and asyncpg to deliver APIs that handle thousands of requests per second.
Every project ships in 12 weeks with a fixed price between $80,000 and $250,000. Our FastAPI engineers build to compliance standards including HIPAA, PCI-DSS, and SOC 2, so you can go to market without security delays.
We work with CTOs who need a scalable API backbone, founders building a SaaS MVP with FastAPI, and fintech or healthcare teams that require certified data handling. Each buyer gets a dedicated project manager and senior developers.
Structured endpoints with FastAPI, auto-generated OpenAPI docs, and input validation via Pydantic models. Includes Alembic for database migrations.
Schema-first GraphQL APIs using Strawberry (Python) with FastAPI as the transport layer. Supports subscriptions and resolver caching.
Decoupled services communicating via RabbitMQ or Kafka. Each service runs as a separate FastAPI instance inside Docker containers.
Bi-directional WebSocket endpoints for live dashboards, chat, or telemetry. Built with FastAPI’s native WebSocket support and Redis pub/sub.
Task queues using Celery with Redis or RabbitMQ, triggered by FastAPI endpoints. Handles email delivery, data exports, and video processing.
A single FastAPI gateway that aggregates multiple downstream services, handles authentication, rate limiting, and request routing.
High-throughput ingestion pipelines for IoT, logs, or ecommerce events. Uses FastAPI with AsyncPG and batch writes to TimescaleDB or ClickHouse.
OAuth2, JWT, or SSO solutions using FastAPI-dep injectable dependencies. Integrates with Auth0, Okta, or custom identity providers.
Here is what our track record looks like.
IRPR has shipped over 200 products, and FastAPI is one of our most requested frameworks. Our senior engineers have built APIs for fintech, healthcare, and ecommerce clients that handle millions of requests per day. Each project starts with a clear Roadmap so you know exactly what ships and when.
We guarantee a 12-week timeline for your MVP. 98% of our projects finish on time and on budget. Every API we build is tested with pytest, monitored with Sentry, and deployed with CI/CD on GitHub Actions. You get full code ownership and a production-ready system.
Not all FastAPI developers deliver the same result. Here is how we compare.
Generic dev shops often assign junior developers to save on cost. They bill by the hour, avoid fixed scopes, and rarely understand compliance. IRPR does the opposite.
We assign senior engineers only, charge a fixed price from the Roadmap, and guarantee delivery in 12 weeks. Our team includes experts in Python, FastAPI, and the compliance standards your industry requires.
Every project follows a repeatable process that removes guesswork.
We break every FastAPI project into four phases. Each phase has clear deliverables and a fixed timeline. You see progress every week and can adjust scope during the Roadmap phase.
After the Roadmap, we build in parallel sprints. Our QA team writes automated tests alongside development. The result is a production-ready API that passes compliance audits and scales with your users.
You get a complete, production-ready system. Not just code.
Every FastAPI project from IRPR includes everything you need to launch and maintain your API. We do not cut corners or leave you with a half-finished prototype.
Our deliverables are designed to hand over to your internal team or to run independently. You own all source code, infrastructure configs, and documentation from day one.
Built a FastAPI pipeline that ingests 500K transactions per minute, performs fraud checks via a Redis-based rules engine, and routes to PostgreSQL. Reduced processing latency from 12 seconds to 800ms. Tech stack: FastAPI, Redis, asyncpg, Celery.
Delivered a multi-tenant billing API with Stripe integration, plan management, and usage tracking. The client launched to 200 beta users in week 12. Tech stack: FastAPI, SQLAlchemy, Stripe, Docker.
Created a secure FastAPI backend for a digital health provider. Included FHIR-based EHR integrations, role-based access, and automatic audit logging. Passed HIPAA audit on first submission. Tech stack: FastAPI, PostgreSQL, OAuth2, AWS KMS.
Replaced a legacy PHP system with a FastAPI microservice handling 50K orders/day. Cut checkout time by 60% and increased payment success rate to 99.5%. Tech stack: FastAPI, RabbitMQ, MongoDB, Stripe.
Built a FastAPI inference service for a route optimization model (ONNX). Handles 1K requests/second with sub-50ms latency. Enabled same-day delivery for 3 new cities. Tech stack: FastAPI, ONNX Runtime, Redis, Kubernetes.
Created a video transcoding pipeline using FastAPI + Celery. Handles 10K uploads/day, transcode to 4 formats, and stores in S3. Reduced processing time per video from 45 minutes to 8 minutes. Tech stack: FastAPI, Celery, FFmpeg, S3.
Every premium FastAPI project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
All our FastAPI developers have 7+ years of Python experience. You never get a junior or offshore engineer learning on your budget.
We ship your MVP in 12 weeks or we work additional weeks at no cost. 98% of our projects finish on time.
IRPR builds HIPAA, PCI-DSS, and SOC 2 compliant APIs. We handle encrypted data, audit logs, and secure authentication out of the box.
You own every line of code, every migration, every config file. No licenses, no locked-in platforms, no hidden restrictions.
You get a PM who runs daily stand-ups, updates your Jira board, and ensures the project stays on track. No disappearing act.
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.
