Professional REST API Development FirmREST API
We build production-grade REST APIs for web and mobile apps. 8-12 week delivery with fixed pricing.
IRPR is a professional REST API development firm that builds secure, scalable APIs using Node.js, Python, Go, and Java. We design endpoints with OpenAPI 3.0 specs and deploy on AWS, GCP, or Azure with auto-scaling and monitoring.
Every REST API project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle authentication (OAuth 2.0, JWT), rate limiting, caching (Redis), and compliance (HIPAA, PCI-DSS, SOC 2). You get full source code ownership and a CI/CD pipeline.
We work with CTOs who need a reliable API layer for their SaaS product, product managers launching a mobile app that requires a backend, and engineering leads who want to offload API development to a senior team without hiring.

Why hire a professional REST API development firm
Building a REST API in-house takes months and costs more than you expect.
IRPR has shipped 200+ REST APIs for clients in 50 countries. Our senior engineers use Node.js, Python, Go, and Java to build APIs that handle millions of requests per day. We write OpenAPI 3.0 specs before writing code, so you know exactly what you get.
Every API includes rate limiting, caching with Redis, authentication via OAuth 2.0 or JWT, and automated testing with 90%+ code coverage. We deploy on AWS ECS, GCP Cloud Run, or Azure App Service with CloudFront CDN and CloudWatch monitoring.
Generic dev shop vs professional REST API development firm
Not all API developers follow the same standards. Here is the difference.
Many agencies skip API documentation, ignore security best practices, and deliver code that breaks under load. IRPR treats every API as a product with specs, tests, and monitoring from day one.
We use OpenAPI 3.0 for documentation, Postman collections for testing, and Datadog for production monitoring. Every endpoint has a rate limit, a timeout, and a retry policy.
- No API documentation
- No rate limiting
- No automated tests
- No CI/CD pipeline
- No monitoring or alerts
- No security audit
- OpenAPI 3.0 spec before coding
- Rate limiting and caching built in
- 90%+ test coverage
- GitHub Actions CI/CD
- Datadog monitoring and alerts
- OAuth 2.0 and JWT authentication
How we build your REST API in 8-12 weeks
Our process is designed to ship fast without cutting corners.
We start with a 2-week Roadmap phase where we define endpoints, data models, and authentication flows. You get a fixed price and a timeline before we write a single line of code.
Then we build in 2-week sprints with demos every Friday. You see working endpoints, test them with Postman, and give feedback. By week 8-12, you have a production-ready API deployed on your cloud account.
What ships with every REST API project
You get more than just code. Every project includes these deliverables.
We hand over everything you need to run, maintain, and scale your API. No black boxes, no hidden dependencies.
All code is in your GitHub repo from day one. You own it fully.
- Source code in your GitHub repo
- OpenAPI 3.0 documentation
- Postman collection with examples
- CI/CD pipeline on GitHub Actions
- Docker containers for local dev
- Sentry error tracking
- Datadog monitoring dashboard
- Rate limiting and caching config
- Authentication (OAuth 2.0 or JWT)
- Deployment guide and runbook
What we ship in this practice.

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.
Senior engineers only
Our team averages 10+ years of experience. No junior developers, no offshore outsourcing. Every engineer has shipped at least 5 production APIs.
OpenAPI 3.0 before code
We write the full API spec before writing any code. You review and approve every endpoint, data model, and authentication flow upfront.
Full code ownership
You own all source code, documentation, and infrastructure from day one. No licensing fees, no vendor lock-in.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs by default. Our engineers know the audit requirements and bake them into the architecture.
99.9% uptime SLA
Every API we deploy comes with Datadog monitoring, automated alerts, and a 99.9% uptime guarantee. We do not ship and walk away.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
