We build high-performance APIs with FastAPI. Get a production-ready MVP in 8-12 weeks with fixed pricing.
IRPR builds high-performance APIs with FastAPI for SaaS, fintech, and healthcare companies. We use Python async, SQLAlchemy, Pydantic, and PostgreSQL to deliver scalable backends.
We ship production-ready FastAPI applications in 8-12 weeks. Pricing ranges from $80K to $250K for a full MVP. Our code meets SOC 2 and HIPAA compliance standards.
Founders building a new SaaS product, CTOs migrating from Flask to FastAPI, and product managers needing a scalable API backend hire us. We also work with enterprise teams adding async capabilities.
Types of software we ship.
REST API Development

Why Hire Experienced FastAPI Consultants
Our FastAPI projects ship faster and run leaner.
We have built over 50 FastAPI-based APIs for clients in fintech, healthcare, and SaaS. Our consultants average 10+ years in Python development.
Every FastAPI project includes automated testing, CI/CD pipelines, and performance benchmarks. We guarantee 99.9% uptime in production.
Generic Python Shops vs IRPR
Not all FastAPI developers deliver production-ready code.
Many freelance developers skip testing and documentation. They use outdated patterns that slow down your team.
IRPR follows strict FastAPI best practices. Every endpoint has type hints, validation, and async handling. We write tests before code.
- No async optimization
- Missing Pydantic validation
- No OpenAPI docs
- No load testing
- No CI/CD
- No security audit
- Async-first design
- Pydantic schemas with validation
- Auto-generated OpenAPI docs
- Load tested with Locust
- CI/CD on GitHub Actions
- Security review with OWASP top 10
Our FastAPI Development Process
We move from idea to deployed API in 8-12 weeks.
Each phase has clear deliverables and fixed milestones. You see working code every two weeks.
We use agile sprints with daily standups and weekly demos. Changes are easy to make early.
What Ships with Every FastAPI Project
You own everything. No black boxes.
We deliver complete source code, database migrations, and deployment scripts. Every project includes a runbook for your team.
We also provide Postman collections, API documentation, and a 30-day support window after launch.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Docker containers for local development
- Kubernetes deployment manifests
- Auto-generated OpenAPI (Swagger) docs
- Pydantic schemas with validation
- Async database session management
- Load test results and optimization report
- Sentry error tracking integration
- 30-day post-launch support
What we ship in this practice.

Why teams hire us.
FastAPI Specialists, Not Generalists
IRPR has shipped 50+ FastAPI projects. Our team knows async patterns, Pydantic optimization, and SQLAlchemy async sessions. We don't learn on your dime.
Fixed Price, Not Hourly
Every FastAPI project gets a fixed quote in the Roadmap phase. No hourly billing, no scope creep charges. You know the cost before we write code.
Production-Ready from Day One
We write tests, set up CI/CD, and configure monitoring in the first sprint. Your API is deployable from week 4. No technical debt.
Performance Guaranteed
We load test every API with 10,000 concurrent users. If your API doesn't meet latency targets, we fix it at no extra cost.
Compliance Built-In
We build FastAPI APIs that meet SOC 2, HIPAA, and PCI-DSS standards. Encryption, audit logs, and access controls are standard.
Full Ownership, No Lock-In
You get all source code, Docker images, and deployment scripts. No proprietary frameworks. You can take the code to any team.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
