Premium FastAPI Development VendorFastAPI Development
Build production-grade APIs with FastAPI. Our senior engineers deliver secure, high-performance backends in 8-12 weeks.
IRPR is a premium FastAPI development vendor. We build async APIs with FastAPI, Pydantic, SQLAlchemy, Redis, and PostgreSQL. Every project uses automated testing and CI/CD from day one.
Our teams ship a production-ready FastAPI backend in 8 to 12 weeks. Fixed pricing starts at $80,000 and goes up to $250,000. We handle compliance for HIPAA, PCI-DSS, and SOC 2 on request.
Startups seeking a scalable API backend, SaaS companies replacing a slow Python or Node.js service, and enterprises migrating from legacy synchronous systems hire us. Fintech and healthcare clients choose us for our compliance experience.
Types of software we ship.

Why choose a premium FastAPI development vendor?
Not every team can deliver production-grade FastAPI. Here is what IRPR guarantees when you hire us.
FastAPI is fast, but building with it correctly requires deep knowledge of async Python, database optimization, and deployment. Our engineers have shipped over 200 products using FastAPI and related tools like Pydantic and SQLAlchemy.
We use automated testing, staging environments, and monitoring from the start. Every API we build hits 99.9% uptime and passes security audits for HIPAA or PCI-DSS when needed.
Generic developer vs IRPR: the real difference
Hiring a single freelancer or a generic agency often leads to delays, undocumented code, and security gaps. Here is how we compare.
A generic developer might write a FastAPI app in a week, but you will get no tests, no CI/CD, and no async best practices. You will pay hourly, the budget will balloon, and you will own messy code without docs.
IRPR gives you a fixed price, a senior team, and a documented, tested, and deployable API. We handle security, compliance, and production monitoring. Your code lives in your repo from day one.
- hourly billing that inflates
- no fixed scope or timeline
- junior or mid-level developers
- no automated tests
- no security review
- no documentation
- fixed price per project
- 8-12 week delivery commitment
- senior engineers only (8+ years)
- CI/CD with 90%+ test coverage
- HIPAA/PCI-DSS ready
- OpenAPI docs auto-generated
Our FastAPI development process
We follow a repeatable 4-phase process. Each phase produces a clear deliverable before moving to the next.
During the Roadmap phase (week 2), we scope every endpoint, data model, and integration. You get a fixed price and timeline before we start coding.
Then we build in 2-week sprints. You see a working API in staging after sprint 1. By week 8-12 you have a production-ready backend with full documentation and deployment scripts.
What ships with every FastAPI project
Every deliverable is production-ready from day one. Here is what you get without asking.
We ship more than code. Each project includes a deployment pipeline, monitoring, and documentation that stays current. You can hand off to your own team or our support team.
All code is owned by you. We never lock you into our infrastructure. You can deploy anywhere, anytime.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- OpenAPI (Swagger) docs auto-generated
- Docker Compose and Dockerfile for local development
- Load testing script (locust or k6) included
- Sentry or Datadog error monitoring configured
- Pydantic validation for all input/output
- JWT or OAuth2 authentication implementation
- Database migration scripts (Alembic)
- Post-launch support for 30 days
What we ship in this practice.

Why teams hire us.
Fixed price, not hourly
Every FastAPI project gets a fixed quote during the Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. We eat the risk if we underestimated.
Senior engineers only
All developers on your project have at least 8 years of Python experience. They have shipped FastAPI backends for Fortune 500 companies and startups alike.
HIPAA and PCI-DSS ready
We have delivered 20+ HIPAA-compliant projects and 15 PCI-DSS certified systems. Our FastAPI middleware handles audit logging, encryption, and access controls by default.
12-week MVP guarantee
We commit to delivering a working, deployable FastAPI backend within 12 weeks. If we miss the deadline, we discount the next phase. This has been our standard for 6 years.
Full source code ownership
You own every line of code written. We store it in your repository from the first commit. No proprietary frameworks, no license fees, no vendor lock-in.
Dedicated project manager
A PM coordinates your team and ours, runs daily standups, and publishes weekly progress reports. You get a single point of contact throughout the project.
