Professional REST API Development TeamDevelopment Team
We build REST APIs that scale to millions of requests. Fixed price, 8-12 week delivery, full ownership.
IRPR builds production-grade REST APIs for B2B SaaS, fintech, healthcare, and ecommerce platforms. We use Node.js, Express, Fastify, PostgreSQL, Redis, and Docker to deliver APIs that handle 10,000+ requests per second with sub-50ms response times.
Every project ships with a fixed price quote in week 2, typically $80K-$250K for a full REST API with auth, rate limiting, logging, and documentation. Our 8-12 week timeline includes automated testing, CI/CD via GitHub Actions, and deployment on AWS or GCP.
We work with CTOs who need a reliable backend for their platform, product managers launching a new API-first product, and founders who want to avoid technical debt from day one. Our clients are in New York, San Francisco, London, and Berlin.

Why Your REST API Needs a Professional Development Team
A poorly built REST API costs you time, money, and customers. Here is what IRPR delivers instead.
A professional REST API development team ensures your endpoints are secure, scalable, and well-documented from day one. IRPR has shipped over 200 APIs across 50 countries, each with automated testing, rate limiting, and monitoring via Sentry and Datadog.
We use Node.js, Express, Fastify, PostgreSQL, Redis, and Docker to build APIs that handle 10,000+ requests per second with sub-50ms latency. Every API includes Swagger/OpenAPI documentation, JWT authentication, and CI/CD pipelines on GitHub Actions.
Generic Dev Shop vs. IRPR: The REST API Difference
Not all development teams are equal. Here is what sets IRPR apart.
Generic dev shops often deliver REST APIs with no documentation, no rate limiting, and no CI/CD. IRPR builds every API with automated testing, Swagger docs, and deployment scripts from the start.
We also include monitoring, error tracking, and a 99.9% uptime guarantee. Our fixed pricing means you know the cost before we write a single line of code.
- No API documentation
- No rate limiting
- No CI/CD pipeline
- No monitoring or alerts
- Hourly billing with scope creep
- Junior developers with no oversight
- Swagger/OpenAPI docs shipped with code
- Rate limiting, auth, and validation built in
- GitHub Actions CI/CD from day one
- Sentry and Datadog monitoring
- Fixed price quote in week 2
- Senior engineers only, 10+ years experience
How IRPR Builds Your REST API in 8-12 Weeks
Our 4-phase process ensures your REST API is production-ready on time and on budget.
We start with a 1-week discovery call to define endpoints, data models, and integrations. Then we move to a 2-week Roadmap phase where we deliver a fixed price quote and detailed technical specification.
The Product phase takes 4-8 weeks of development with weekly demos. The Release phase includes load testing, security audit, and deployment with a 99.9% uptime guarantee.

Every API comes with these deliverables included in the fixed price.
You get full ownership of the source code, a CI/CD pipeline, and monitoring tools. No black boxes, no ongoing fees.
We also include a 30-day post-launch support period to handle any issues or questions.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking
- Datadog performance monitoring
- Swagger/OpenAPI documentation
- Rate limiting and auth (JWT or OAuth2)
- Load test report (k6 or Artillery)
