CTOs at funded startups hire us to build their core API infrastructure. Enterprise architects engage us for microservices and integration APIs. Product managers trust us to deliver scalable REST APIs that power mobile and web applications.
Types of software we ship.
REST API for Mobile Apps
Build fast, secure mobile backends with REST APIs. Integrate push notifications, user auth, and real-time data using Firebase and AWS.
REST API for Microservices
Decouple monolithic apps into modular microservices. Use Docker, Kubernetes, and gRPC alongside REST for internal service communication.
REST API for Third-Party Integrations
Connect your app to Salesforce, HubSpot, Stripe, and more. We build custom REST endpoints that sync data bi-directionally.
REST API for IoT Devices
Handle millions of device connections with lightweight REST APIs. Use MQTT bridges and AWS IoT Core for device management.

Why IRPR Is the Top Choice for REST API Development Developers
IRPR has shipped over 200 REST APIs for clients in 50+ countries. We deliver on time, on budget, with senior engineers only.
Every REST API we build includes OpenAPI 3.1 documentation, automated unit and integration tests, and a CI/CD pipeline using GitHub Actions. We deploy to AWS, GCP, or Azure based on your infrastructure needs.
Our APIs handle 100,000+ requests per minute out of the box. With caching layers, database indexing, and horizontal scaling, your API stays fast under load. We also configure Sentry error tracking and Datadog monitoring so you know when something breaks.
Generic Development Shops vs IRPR: The Real Difference
Most agencies bill hourly and hand off half-baked code. IRPR gives you a fixed price, senior engineers, and a shipped product you own.
Generic shops often assign junior developers, change requirements mid-project, and deliver APIs with poor documentation. You end up paying more for less.
IRPR assigns a senior engineer as your lead. We scope the project in a 1-week Roadmap phase (week 2), give you a fixed price, and ship in 8-12 weeks. You get full code ownership, Postman collections, and a 30-day post-launch support window.
- Junior engineers learning on your dime
- Hourly billing with no cap
- No written API contract or documentation
- Vague timelines that slip weeks
- Code that doesn't scale beyond 100 users
- No compliance expertise (HIPAA, PCI, SOC 2)
- Senior engineers with 8+ years of experience
- Fixed price quoted in week 2 (Roadmap phase)
- OpenAPI docs, Postman collections, integration tests shipped
- 8-12 week delivery, 98% on-time
- Architectured for 100,000+ requests per minute
- HIPAA, PCI, SOC 2, GDPR compliance built in
Our 4-Step REST API Development Process
From idea to production in 8-12 weeks. Our process eliminates surprises.
IRPR follows a structured flow that starts with a deep audit of your requirements and ends with a deployed, documented API. Each step includes a sign-off milestone.
You are never left guessing. Every phase delivers a concrete artifact: a roadmap document, API contract, testing report, or deployment script.
What Ships With Every REST API Project
You get more than just code. Every deliverable is production-ready and documented.
IRPR treats documentation and tooling as first-class deliverables. Without them, an API is just endpoints that no one can use or debug.
Everything listed below is included in your fixed price. No add-ons, no hidden costs.
- Source code in your GitHub/GitLab repo
- OpenAPI 3.1 specification (YAML/JSON)
- Postman collection with environment variables
- CI/CD pipeline using GitHub Actions
- Automated unit and integration tests (80%+ coverage)
- Dockerized local development environment
- Sentry error tracking configured
- Datadog monitoring dashboard
- Deployment playbook and runbook
- 30-day post-launch support window
