We ship production-ready FastAPI backends in 8-12 weeks. Fixed price, senior engineers, zero fluff.
IRPR builds high-performance FastAPI applications for APIs, microservices, and data pipelines. We use Pydantic for data validation, SQLAlchemy for async database access, and Docker for consistent deployments.
Every project ships with automated CI/CD, unit tests in pytest, and monitoring via Sentry. Typical timelines are 8 to 12 weeks, with fixed prices from $80K to $250K. We support HIPAA, PCI-DSS, and SOC 2 compliance when required.
Our clients are CTOs scaling API-first products, startup founders launching MVPs, enterprise teams migrating to asynchronous Python, and data engineering leads requiring high-throughput services.
Stateless, versioned REST APIs using FastAPI, Pydantic, and async SQLAlchemy. Includes OpenAPI docs and JWT auth.
GraphQL endpoint with Strawberry or Ariadne, resolving via async FastAPI handlers. Supports query batching and subscriptions.
Event-driven streaming with FastAPI, Kafka or Redis Streams. Processes 10k+ events per second with low latency.
FastAPI serving machine learning models via ONNX or TensorFlow. Includes request validation and prediction caching.
Unified gateway connecting Slack, Stripe, Salesforce, and more. Uses Celery for async retries and rate limiting.
Isolated, scalable microservice built with FastAPI, deployed via Docker Compose or Kubernetes. Service mesh ready.
Real-time bidirectional communication using FastAPI WebSocket support. Suitable for chat, notifications, live dashboards.
FastAPI-based gateway routing requests to multiple backends. Includes token bucket rate limiting and request logging.
We've built over 200 production systems using FastAPI, with measurable results.
Every FastAPI project we deliver includes async endpoints, proper exception handling, and automated tests. Our engineers average 10+ years of Python experience and have shipped APIs handling 100k+ requests per second.
We use the same tools whether the project is a simple CRUD API or a real-time streaming service. That means faster development, fewer surprises, and predictable delivery.
Not all FastAPI developers deliver the same quality.
Generic shops often rely on sync frameworks like Flask or Django and treat FastAPI as just another router. They skip async patterns, miss performance tuning, and deliver code that fails under load.
IRPR uses only senior engineers who write async from day one. We enforce type hints, Pydantic validation, and strict test coverage. The result is code that scales and stays maintainable.
Our proven process from idea to production.
We follow a four-phase approach that guarantees your FastAPI backend is built on time, within budget, and ready for production.
Everything you need to run in production.
We deliver more than just code. Every project includes a complete production-ready package.
Built a FastAPI event ingestion service handling 10k requests per second. Used Redis Streams for buffering and ClickHouse for analytics. Reduced query latency by 80%.
HIPAA-compliant FastAPI backend for a telehealth startup. Managed 500k patient records with PostgreSQL and Alembic. Achieved 99.99% uptime with zero data leaks.
PCI-DSS Level 1 compliant API integrating Stripe, PayPal, and Braintree. Used FastAPI, Celery, and Redis. Processed $5M in transactions in the first month.
FastAPI backend serving 1 million product SKUs with sub-100ms response times. Used Elasticsearch for full-text search and Redis for caching. Integrated with Shopify and Magento.
FastAPI serving TensorFlow models for route optimization. Handled 500 concurrent requests with ONNX runtime. Achieved 99.9% uptime and reduced fuel costs by 15%.
WebSocket-powered real-time feed using FastAPI and MongoDB. Supported 50k concurrent connections and delivered posts within 200ms.
Every FastAPI project gets a fixed quote after a 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges.
Our engineers average 10+ years of Python experience and have shipped FastAPI applications handling 100k+ req/s. We don't hire juniors or outsource.
We write typed, tested, and documented code from the first commit. Every project ships with 90%+ unit test coverage and automated CI/CD.
You own 100% of the code, documentation, and infrastructure configurations. We never hold IP or require royalties.
You see working software every week. We share a live demo environment and a public Jira board so you track progress in real time.
Every project includes 30 days of free support after launch. We fix bugs, answer questions, and help with your first production release.
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.
