We build production-ready FastAPI backends in 8-12 weeks. Fixed price, senior engineers, and full compliance built in.
IRPR builds production-grade APIs with FastAPI, Pydantic, SQLAlchemy, and async PostgreSQL. Every project starts with a clear architecture that handles 10K+ concurrent requests from day one.
We ship a fully tested, documented FastAPI backend in 8-12 weeks. Pricing is fixed between $80K and $250K depending on scope. All projects meet HIPAA, PCI-DSS, or SOC 2 compliance as needed.
Our clients include CTOs of Series A SaaS startups, engineering leads at fintech companies, healthcare platform founders, and product managers at enterprise IT teams. They hire us when they need a senior team that delivers on time and on budget.
CRUD APIs with automatic OpenAPI docs. Uses Pydantic models, async endpoints, and PostgreSQL with Alembic migrations.
Bi-directional event streaming for chat, live dashboards, and notifications. Uses WebSockets with Redis Pub/Sub and async handlers.
Decoupled services communicating via gRPC or message queues. Uses FastAPI for each service, Docker Compose, and Kubernetes for deployment.
Ingest, transform, and serve large datasets. Uses FastAPI with async batch processing, Celery workers, and S3 object storage.
Serve ML models with low latency. Integrates ONNX Runtime or TensorFlow Serving behind FastAPI endpoints with caching via Redis.
Unify multiple external APIs under a single interface. Uses FastAPI with OAuth2, rate limiting, and async HTTPX clients.
Role-based admin panel with custom analytics endpoints. Uses FastAPI with SQLAdmin, Celery for reports, and async rendering.
Centralized auth with JWT, OAuth2, and social login. Uses FastAPI with passlib, jose, and PostgreSQL for user management.
Our clients get production APIs that handle real traffic from day one.
Every FastAPI backend we build includes async requests, connection pooling, and database indexing for sub-50ms P99 latency. We load test every endpoint using locust with 10,000 virtual users before going live.
We have shipped 200+ products across 50+ countries with a 98% on-time delivery record. Our average project ships in 12 weeks, from architecture to production deployment.
Not all FastAPI consultants are the same. Here is the difference.
Most dev shops charge hourly and hand you incomplete code with no docs or CI/CD. They treat compliance as an afterthought, and you end up paying twice to fix it later.
IRPR delivers a fully tested, documented, and deployed API with a fixed price. We handle HIPAA, PCI-DSS, and SOC 2 from day one so you never have to rearchitect.
We move from idea to production API in 12 weeks.
Our process is designed to remove uncertainty. You see the full architecture, get a fixed price, and watch the API take shape in two-week sprints.
Every sprint ends with a working demo. We deploy to staging on week 10 and production on week 12.
You get everything needed to run and maintain the API yourself.
We don't just write code. We give you the complete setup so your team can take over immediately.
All artifacts are in your repository from the first commit.
Built a FastAPI backend that connects Plaid, Stripe, and custom ledger services. Reduced payment processing latency by 60%, handling 5,000 transactions per second with 99.9% uptime. Tech stack: FastAPI, PostgreSQL, Stripe Connect, Redis.
Created a patient-facing FastAPI API for video scheduling, e-prescriptions, and lab results. Passed HIPAA audit on first attempt. Achieved 200ms average response time for 10,000 concurrent users. Tech stack: FastAPI, PostgreSQL, Twilio, AWS KMS.
Developed a WebSocket-powered FastAPI service for a national ecommerce brand. Updates inventory across 50 warehouses in under 1 second. Reduced stockout incidents by 80%. Tech stack: FastAPI, Redis, PostgreSQL, AWS Lambda.
Built a FastAPI data ingestion endpoint handling 1 million events per hour. Used Kafka for buffering and ClickHouse for real-time queries. Delivered sub-second dashboard refresh for marketing team. Tech stack: FastAPI, Kafka, ClickHouse, S3.
Designed a FastAPI backend with row-level security and tenant isolation for a B2B analytics platform. Onboarded 200+ tenants in the first month without any performance degradation. Tech stack: FastAPI, PostgreSQL (schema-per-tenant), Redis, Docker.
Created a centralized auth service supporting OAuth2, SAML, and social login for a Fortune 500 company. Cut login failure rate from 3% to 0.1%. Tech stack: FastAPI, Auth0, PostgreSQL, Redis.
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. If scope changes, we amend the quote before work begins.
Our team averages 10+ years of experience building production APIs. Every engineer has shipped FastAPI backends handling millions of requests. You never get junior developers.
We embed HIPAA, PCI-DSS, and SOC 2 controls into the architecture from the first commit. No retrofitting. Our audit trail is ready for third-party review.
We work async with 4+ hours of overlap with US time zones. You communicate via Slack and Notion, review code via GitHub, and get weekly video demos. No endless meetings.
Our standard delivery timeline is 8-12 weeks for a complete FastAPI backend. We beat this 98% of the time. If we miss, you pay nothing for the overage.
You own every line of code from the first commit. We never license or resell your IP. Your repository is yours, and you can deploy 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.
