Senior REST API Development DevelopersREST API
We build production-grade REST APIs with Node.js, Python, and Go. 200+ products shipped, 8-12 week timelines, fixed pricing.
IRPR builds REST APIs for web apps, mobile backends, and microservices. We use Node.js (Express, Fastify), Python (FastAPI, Django REST), and Go (Gin, Echo) to deliver fast, secure endpoints.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle authentication (JWT, OAuth 2.0), rate limiting, caching (Redis), and compliance (HIPAA, PCI-DSS, SOC 2).
CTOs hire us to replace slow internal teams. Startup founders hire us to build their first API. Enterprise architects hire us to migrate legacy SOAP to REST. Product managers hire us to add API integrations for Stripe, Salesforce, or HubSpot.

Why senior REST API development developers matter
A poorly designed REST API costs you time, money, and customers.
IRPR's senior REST API development developers have shipped over 200 APIs. We follow OpenAPI 3.0 specs, enforce idempotency, and write automated tests with 95%+ coverage. Every endpoint is documented with Swagger UI.
We use PostgreSQL for relational data, Redis for caching, and RabbitMQ for async jobs. Our APIs handle 10,000+ requests per second with sub-50ms response times. We deploy on AWS ECS or Kubernetes with auto-scaling.
Generic dev shop vs IRPR senior REST API development developers
Not all API developers are equal. Here is the difference.
Generic shops hand you code with no tests, no docs, and no SLA. You pay hourly and hope for the best. IRPR delivers a production-ready API with CI/CD, monitoring, and a fixed price.
We write integration tests, load tests, and security scans before day one of production. Every API ships with a Postman collection and a deployment guide.
- No API contract upfront
- Hourly billing with no cap
- No automated tests
- No documentation
- No monitoring or alerts
- No post-launch support
- OpenAPI 3.0 spec before coding
- Fixed price from Roadmap phase
- 95%+ test coverage
- Swagger UI docs included
- Sentry + Datadog monitoring
- 2 weeks free post-launch support
How we build your REST API in 8-12 weeks
Our process is designed for speed and quality.
We start with a 2-week Roadmap phase where we define endpoints, data models, and auth flows. You get a fixed price and a timeline before any code is written.
Then we build in 2-week sprints. You see working endpoints every 14 days. We deploy to staging on week 4 and production on week 8-12.
What ships with your REST API
Every project includes these deliverables by default.
You get more than just code. Every API ships with documentation, tests, and deployment scripts. No hidden extras.
- OpenAPI 3.0 spec file
- Swagger UI documentation
- Postman collection with examples
- Automated test suite (95%+ coverage)
- CI/CD pipeline on GitHub Actions
- Dockerized deployment
- Sentry error tracking
- Datadog performance monitoring
- Source code in your private repo
- 2 weeks free post-launch support

Senior engineers only
Our team averages 10+ years of experience. Every developer has shipped at least 5 production REST APIs. No juniors, no offshore outsourcing.
OpenAPI first
We write the API contract before any code. You review and approve every endpoint, schema, and auth flow. No guesswork.
Production-ready from day one
Every API ships with CI/CD, monitoring, and automated tests. We deploy to AWS ECS or Kubernetes with auto-scaling and 99.9% uptime.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant APIs. Encryption at rest and in transit, audit logs, and role-based access control are standard.
You own the code
Full source code is delivered to your private GitHub repo. No licensing fees, no lock-in, no recurring payments.
