We build production-grade APIs with FastAPI. Fixed price, senior engineers, 12 weeks to launch.
IRPR is a leading FastAPI development company. We build high-performance APIs using FastAPI with Python 3.12, Pydantic v2 for data validation, SQLAlchemy for database access, and async endpoints for maximum throughput. Our team has shipped over 200 products using this stack.
Every project ships in 8-12 weeks for a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. You get full source code ownership, CI/CD pipelines, and production monitoring from day one.
We work with CTOs who need a scalable API backend, startup founders launching a SaaS product, enterprise architects modernizing legacy systems, and healthcare IT directors who require HIPAA-compliant data exchange. Each gets a dedicated senior engineer who writes production code from week one.
Build stateless REST APIs with FastAPI, Pydantic schemas, and async SQLAlchemy. Includes OpenAPI docs and JWT auth.
Implement GraphQL endpoints using Strawberry or Graphene with FastAPI. Supports subscriptions, real-time data, and federation.
Design and deploy FastAPI microservices with Docker, Kubernetes, and message brokers like RabbitMQ or Redis.
Build WebSocket-based streaming APIs with FastAPI for live dashboards, chat, and IoT data ingestion.
Create ETL APIs with FastAPI, Celery, and PostgreSQL for batch processing and event-driven data flows.
Wrap machine learning models in FastAPI endpoints with async inference, model caching, and GPU support.
Build integration layers with FastAPI to connect Stripe, Salesforce, HubSpot, Twilio, and other SaaS platforms.
Develop admin panel backends with FastAPI, SQLAlchemy, and React frontend. Includes role-based access and audit logs.
We have built over 200 products with FastAPI and Python. Here is what that experience means for your project.
FastAPI is the fastest-growing Python web framework in production use. It handles 50,000 requests per second on a single instance with async support. We have used it to build APIs for healthcare, fintech, and SaaS companies that process millions of transactions daily.
Our senior engineers have an average of 10 years of Python experience. They write tests, set up CI/CD with GitHub Actions, deploy to AWS or GCP, and configure Sentry monitoring. Every project includes a road map phase where we define the API contract before writing a single line of code.
Most agencies overpromise and underdeliver. Here is how we are different.
Generic development shops often assign junior developers, use hourly billing, and deliver late. They write code that works locally but fails in production. They do not set up monitoring, logging, or CI/CD unless you ask.
IRPR assigns senior engineers only. We give you a fixed price in week two. We write production-grade code from day one. You get a CI/CD pipeline, error tracking, and performance monitoring built into the price.
We use a four-phase process to build your API. Each phase has a clear deliverable.
The process starts with a 2-week road map phase. We define the API contract, data model, and deployment architecture. You get a detailed document with endpoints, schemas, and a timeline. No surprises.
Then we build, test, and deploy in 6-10 weeks. You see working code every week. We deploy to staging by week 4 and production by week 8. You own the code from day one.
Every project includes these deliverables by default. No add-ons, no hidden costs.
We believe in shipping production-ready code. That means your API is not just working locally. It is deployed, monitored, and documented from day one.
You get everything you need to run and maintain the API yourself. Or we can stay on for ongoing support. The choice is yours.
Built a HIPAA-compliant FastAPI backend for a telemedicine startup. The API handles 10,000 patient data requests per hour with FHIR integration. Tech stack: FastAPI, PostgreSQL, Redis, AWS ECS.
Developed a PCI-DSS compliant payment API using FastAPI and Stripe Connect. Processed $50M in transactions in the first year. Tech stack: FastAPI, Stripe, PostgreSQL, Docker.
Built a FastAPI backend for a B2B SaaS platform with 500+ tenants. API handles 50,000 requests per minute with sub-50ms latency. Tech stack: FastAPI, SQLAlchemy, Redis, AWS RDS.
Created a WebSocket-based inventory tracking API for a logistics company. Reduced stock discrepancies by 90% with real-time updates. Tech stack: FastAPI, WebSockets, Redis, PostgreSQL.
Wrapped a computer vision model in a FastAPI endpoint for a manufacturing client. Serves 1,000 inference requests per second with GPU acceleration. Tech stack: FastAPI, PyTorch, NVIDIA Triton, GCP.
Built a FERPA-compliant FastAPI backend for an edtech company. API serves 100,000 students with personalized content recommendations. Tech stack: FastAPI, PostgreSQL, Redis, AWS Lambda.
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write code.
We do not hire juniors. Every engineer has 10+ years of Python experience and has shipped at least 5 FastAPI projects. You get a lead engineer who writes production code.
We write tests, set up CI/CD, and configure monitoring from week one. Your API is deployed to staging by week 4 and production by week 8. No throwaway prototypes.
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into the architecture. Every endpoint is secured with OAuth2, JWT, or API keys. Audit logs are standard.
You own all source code, documentation, and infrastructure config from day one. No licensing fees, no lock-in, no recurring royalties. You can take the code anywhere.
Every project includes 30 days of post-launch support. We fix bugs, optimize performance, and help your team take over. Extended support is available at a fixed monthly rate.
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.
