Experienced FastAPI Development StudioDevelopment Studio
We build production-ready FastAPI backends for SaaS and data-heavy apps. Ship in 8-12 weeks with fixed pricing.
IRPR builds production-grade FastAPI backends for web apps, APIs, and microservices. We use FastAPI with Pydantic, SQLAlchemy, and async PostgreSQL for high-performance data handling.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance like HIPAA, SOC 2, and PCI-DSS when needed.
Founders, CTOs, and product managers hire us when they need a reliable backend built fast. We work with startups scaling their MVP and enterprises modernizing legacy systems.

Why choose an experienced FastAPI studio
FastAPI is powerful but complex. Here's what we deliver.
IRPR has shipped over 200 products using FastAPI. Our senior engineers know how to design async endpoints, manage database sessions, and handle background tasks.
We focus on production readiness from day one. Every project includes CI/CD, monitoring, and automated testing.
Generic dev shop vs IRPR
Not all FastAPI developers are equal.
Many shops write FastAPI like Flask and miss async patterns. They skip Pydantic validation and ship fragile APIs.
IRPR builds FastAPI backends that scale. We use best practices from the start so you don't rewrite later.
- No async expertise
- No Pydantic validation patterns
- No CI/CD setup
- No production monitoring
- No compliance knowledge
- Hourly billing with scope creep
- Async-first FastAPI architecture
- Pydantic schemas with validation
- GitHub Actions CI/CD pipeline
- Sentry + Datadog monitoring
- HIPAA/SOC2/PCI-DSS ready
- Fixed price, no surprises
How we build your FastAPI backend
We follow a proven process from idea to production.
Every FastAPI project starts with a Roadmap phase to define endpoints, data models, and integrations. You get a fixed quote before any code is written.
We then build the backend in sprints, deploying to staging after each sprint. You see working code every 2 weeks.
What ships with your FastAPI project
Every project includes these deliverables.
We don't hand over prototype code. Your FastAPI backend comes with everything needed to run in production.
- Full FastAPI source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- PostgreSQL database schema with Alembic migrations
- Pydantic models for request/response validation
- JWT authentication and role-based access control
- OpenAPI documentation (Swagger UI)
- Docker Compose and Dockerfile for local development
- Sentry error tracking and Datadog monitoring
- Load testing results with Locust
- Deployment guide and runbook
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every FastAPI project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
All FastAPI projects are built by senior developers with 10+ years of Python experience. No junior developers, no outsourcing.
Production-ready from day one
Your FastAPI backend ships with CI/CD, monitoring, and automated tests. We don't hand over prototype code.
Compliance built in
We build HIPAA, SOC 2, and PCI-DSS compliant FastAPI backends. Our team has passed 50+ compliance audits.
Async-first architecture
We use async endpoints, async database drivers, and background tasks from the start. Your API handles thousands of concurrent requests.
Full ownership and documentation
You own the entire codebase and infrastructure. We provide a deployment guide and runbook so your team can take over.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
