Leading REST API Development StudioDevelopment Studio
We build REST APIs that ship in 8-12 weeks. Fixed price, senior engineers, full ownership.
IRPR is a leading REST API development studio. We build REST APIs using Node.js, Python, Go, and Java with OpenAPI 3.0 specs, JWT authentication, and PostgreSQL or MongoDB databases.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance for HIPAA, PCI-DSS, SOC 2, and FERPA. You get full source code ownership and a CI/CD pipeline on GitHub Actions.
CTOs hire us to replace legacy SOAP APIs with modern REST endpoints. Product managers hire us to build the backend for their SaaS MVP. Startup founders hire us to create a scalable API layer before their Series A.

Why choose a leading REST API development studio
IRPR has shipped 200+ REST APIs for clients in 50+ countries.
A leading REST API development studio brings senior engineers who have built APIs at scale. Our team averages 10+ years of experience. We use OpenAPI 3.0 to document every endpoint before writing code. This means your frontend team can start integration on day one.
We also handle deployment. Every API gets a Docker container, a Kubernetes manifest, and a CI/CD pipeline on GitHub Actions. We set up Sentry for error tracking and Datadog for monitoring. Your API ships with 99.9% uptime SLA.
Generic dev shop vs leading REST API development studio
Not all API teams are equal. Here is what IRPR does differently.
Generic dev shops often start coding without a spec. They use hourly billing and change scope mid-project. Their APIs lack documentation, rate limiting, and proper error handling. You end up with a fragile system that breaks in production.
IRPR starts with a Roadmap phase. In week 2, you get a fixed price, a timeline, and an OpenAPI spec. We build with authentication, logging, and monitoring from day one. Every endpoint has unit tests and integration tests. You get full ownership of the code.
- No API spec before coding
- Hourly billing with scope creep
- No rate limiting or auth
- No documentation
- No CI/CD pipeline
- No monitoring or error tracking
- OpenAPI 3.0 spec in week 2
- Fixed price from Roadmap phase
- JWT + OAuth 2.0 built in
- Auto-generated Swagger docs
- GitHub Actions CI/CD
- Sentry + Datadog monitoring
How we build your REST API in 4 phases
Our process is designed for speed and clarity.
We follow a 4-phase process: Idea, Roadmap, Product, Release. Each phase has clear deliverables and a fixed price. You know exactly what you get and when.
The Roadmap phase takes 2 weeks. You get a detailed spec, a wireframe, and a fixed quote. The Product phase takes 6-10 weeks. We build the API, write tests, and deploy to staging. The Release phase includes load testing, security audit, and production deployment.
What ships with every REST API project
Every project includes these deliverables by default.
You get more than just code. Every API ships with documentation, tests, and deployment infrastructure. No hidden costs or surprises.
We also include a 30-day warranty after launch. If anything breaks, we fix it within 24 hours. You can extend support with a monthly retainer.
- OpenAPI 3.0 spec in YAML format
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Docker container and docker-compose file
- Kubernetes manifests for production
- Sentry error tracking integration
- Datadog monitoring dashboard
- Unit tests with 90%+ coverage
- Integration tests for all endpoints
- Postman collection for manual testing
What we ship in this practice.
SaaS backend for a project management tool
Built a REST API with Node.js, Express, and PostgreSQL. Handles 10,000 concurrent users with rate limiting and caching via Redis. Reduced server costs by 40% compared to the previous monolithic app.
HIPAA-compliant API for a telemedicine platform
Developed a REST API with Python, FastAPI, and FHIR standards. Integrated with Epic EHR for patient data sync. Passed HIPAA audit on first attempt. Reduced patient data retrieval time from 5 minutes to 10 seconds.
Payment processing API for a fintech startup
Created a PCI-DSS compliant REST API using Go and Stripe Connect. Handles 50,000 transactions per day with 99.99% uptime. Reduced chargeback rate by 25% through improved error handling.
Ecommerce API for a multi-vendor marketplace
Built a REST API with Node.js, MongoDB, and Shopify integration. Supports 500 vendors with real-time inventory sync. Increased order processing speed by 60%.
MLS-integrated API for a real estate platform
Developed a REST API with Java Spring Boot and Redis. Connects to 10 MLS providers for property data. Reduced property search latency from 3 seconds to 200 milliseconds.
Data export API for a logistics company
Created a REST API with Python and BigQuery. Exports shipment data in JSON and CSV formats with pagination and filtering. Reduced manual reporting time by 15 hours per week.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the cost before we write a line of code.
Senior engineers only
Our team averages 10+ years of experience. No junior developers. Every engineer has shipped at least 5 production REST APIs. You get a lead engineer who stays on your project from start to finish.
OpenAPI spec before code
We write the OpenAPI 3.0 spec in week 2. Your frontend team can start integration immediately. No waiting for endpoints to be built. The spec becomes the single source of truth.
Full code ownership
You own all source code, documentation, and infrastructure files. No licensing fees, no vendor lock-in. We transfer everything to your GitHub account at the end of the project.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and FERPA compliance into the API from day one. No retrofitting. We use encryption at rest and in transit, audit logging, and access controls.
99.9% uptime SLA
Every API ships with a monitoring stack: Sentry for errors, Datadog for performance, and PagerDuty for alerts. We guarantee 99.9% uptime in production. If it goes down, we fix it within 1 hour.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
