Affordable FastAPI Development StudioDevelopment Studio
We build production-grade APIs with FastAPI, Python 3.12, and PostgreSQL. Ship your MVP in 8-12 weeks at a fixed price starting at $80K.
IRPR builds production-grade APIs and microservices using FastAPI. We use Pydantic for validation, SQLAlchemy for ORM, and test with pytest. Every API ships with OpenAPI docs and async database access.
We deliver FastAPI code in your repo, CI/CD on GitHub Actions, Sentry error monitoring, and AWS or DigitalOcean deployment. Typical timeline is 8-12 weeks. Fixed pricing ranges from $80K to $250K depending on scope. We also handle HIPAA, PCI-DSS, and SOC 2 compliance requirements.
CTOs and startup founders who need a scalable API backend without hiring a full team. Product managers migrating from Flask or Django to async FastAPI. Agencies that need a reliable API partner for client projects. Enterprise teams building data-heavy services for fintech or healthtech.
Types of software we ship.
REST API Development
Custom RESTful APIs with FastAPI, versioned endpoints, and OpenAPI docs. Integrates with PostgreSQL, Redis, and Stripe.
GraphQL API Development
Combine FastAPI with Strawberry or Ariadne for efficient GraphQL queries. Includes real-time subscriptions via WebSocket.
Microservices Architecture
Decompose monolithic apps into independent FastAPI services. Uses Docker, Kubernetes, and message queues like RabbitMQ.
Real-time Data APIs
Build WebSocket endpoints with FastAPI for live dashboards and notifications. Handles 10k+ concurrent connections.
E-Commerce Backend
Product catalog, cart, and checkout APIs built with FastAPI, Stripe, and Celery for async order processing.
SaaS API Backend
Multi-tenant API backends with FastAPI, JWT authentication, and usage-based billing via Stripe.
Data Pipeline APIs
Ingest, transform, and serve data through FastAPI endpoints. Uses Kafka, TimescaleDB, and Apache Parquet.
Admin Dashboard APIs
FastAPI backends for admin panels, with role-based access control and audit logs. Integrates with React or Vue frontends.
We build for every business type.

FastAPI development with proven metrics
We have built over 200 products with FastAPI and related technologies.
Every FastAPI project at IRPR starts with a structured 4-phase process. We define scope, build with senior engineers, and deploy with monitoring. Our clients see results within weeks, not months.
We track delivery metrics closely: 98% of projects ship on time, and average MVP delivery is 12 weeks. Our fixed-price model means no budget overruns. You know the cost before we write a line of code.
What sets IRPR apart from generic dev shops
Not all development studios deliver the same quality.
Many agencies charge by the hour and leave scope unclear. They assign junior developers, skip documentation, and keep code ownership ambiguous. The result is slow delivery and costly surprises.
IRPR works differently. We fix the price after a 2-week roadmap. You get senior engineers, full documentation, and code in your repo from day one. Every project ships with CI/CD and monitoring.
- hourly billing with no cap
- scope creep without change control
- junior or mid-level developers
- no API documentation by default
- slow response to questions
- code ownership uncertain
- fixed price from the start
- scope defined in a paid 2-week roadmap
- senior engineers only (10+ years experience)
- OpenAPI docs included in every project
- response within 24 hours
- full code ownership; code in your repo
Our 4-phase process for your FastAPI MVP
We follow a clear 4-phase process to ship your FastAPI MVP on time and on budget.
Every project begins with a Discovery Sprint where we define your core requirements and user stories. This takes one week and ends with a validated prototype decision.
Then we move to the Roadmap phase, which produces a fixed scope, timeline, and price. After agreement, we build and test in sprints, then deploy and support for one month post-launch.
What ships with every FastAPI project
Every FastAPI project at IRPR ships with these deliverables by default.
We don't cut corners. From day one, you have full ownership of the source code, infrastructure, and documentation. Our goal is to make your team self-sufficient after launch.
- Source code in private GitHub repo
- CI/CD pipeline on GitHub Actions
- PostgreSQL database schema with migrations
- Pydantic models for request/response validation
- OpenAPI (Swagger) docs served at /docs
- Docker Compose for local development
- Deployment scripts for AWS or DigitalOcean
- Sentry error tracking configured
- API load testing suite with Locust
- 1-month post-launch support and bug fixes
What we ship in this practice.
SaaS subscription platform backend
Built a multi-tenant FastAPI backend with Stripe billing, user management, and usage tracking. Reduced signup time by 40%. Tech stack: FastAPI, PostgreSQL, Stripe, Redis.
Real-time analytics dashboard API
