Leading Node.js API Development AgencyAPI Development
We build production-grade REST and GraphQL APIs for SaaS platforms and enterprise systems. Deploy in 8-12 weeks with fixed pricing and full code ownership.
IRPR builds scalable Node.js APIs for web and mobile applications. We use Express.js, Fastify, PostgreSQL, Redis, and deploy on AWS ECS with auto-scaling.
A complete API ships in 8-12 weeks with fixed pricing from $80K to $250K. We handle authentication, rate limiting, logging, and monitoring. Compliance standards include HIPAA for healthcare and PCI-DSS for fintech.
CTOs building SaaS platforms need reliable APIs that scale. Product managers launching mobile apps require fast data sync. Enterprise architects modernizing legacy systems look for microservices APIs. Startup founders building MVPs need an API-first architecture.
Types of software we ship.
REST API Development
Build RESTful APIs with Express.js and PostgreSQL. Includes JWT authentication, rate limiting, and Swagger documentation.
GraphQL API Development
Develop GraphQL APIs using Apollo Server with schema stitching and real-time subscriptions. Integrates with any data source.
Microservices API Development
Design microservices architectures with Node.js, Docker, and Kubernetes. Service mesh with gRPC for internal communication.
API Integration Services
Connect third-party services like Stripe, Salesforce, and HubSpot via custom API adapters. Handle webhooks and rate limits.
Real-Time API (WebSocket) Development
Build real-time APIs with Socket.io or WebSockets for live data sync. Used in chat apps, live dashboards, and collaborative tools.
Serverless API Development
Deploy serverless APIs on AWS Lambda with API Gateway. Auto-scales to zero when idle, reducing costs.
API Gateway Development
Create centralized API gateways with Kong or Express Gateway for routing, authentication, and throttling across services.
Data API Development
Build read-optimized APIs for analytics and reporting. Use Elasticsearch or PostgreSQL read replicas for fast queries.
We build for every business type.

Node.js API development at scale
We have delivered over 200 APIs for clients in 50+ countries.
Each API is built with production-grade monitoring, auto-scaling, and security. Our clients include SaaS platforms handling 1M+ requests per day.
We use a fixed-price model that eliminates surprises. Every API ships with a 99.9% uptime SLA and full documentation.
Why leading businesses choose IRPR
Most API development projects fail due to poor communication and scope creep.
Generic agencies treat API development as a black box. They estimate loosely, delay deployments, and hand over undocumented code.
IRPR flips the model. We deliver a fixed price, full code ownership, and compliance from the start. Our engineers communicate daily with your team.
- Fixed price? No
- Code ownership? Unclear
- Compliance? Not guaranteed
- Communication? Time zone lag
- Scalability? Not built for it
- Post-launch support? None
- Fixed price from Roadmap phase
- Full code ownership in your repo
- HIPAA and PCI-DSS compliance built in
- Daily standups with 4+ hour overlap
- Auto-scaling from day one
- 3 months post-launch support included
Our API development process
We ship production-ready APIs in 8-12 weeks using a four-phase process.
Every project starts with a discovery session where we map endpoints, data models, and auth flows. You get a clear roadmap with no ambiguity.
During builds we run two-week sprints with continuous deployments. Each sprint ends with a testable staging environment.
What ships with every API project
Every deliverable is documented and in your control.
We do not hand over a black box. You get everything needed to operate and extend the API.
- Source code in your GitHub repo
- Swagger/OpenAPI documentation
- CI/CD pipeline with GitHub Actions
- Docker Compose for local development
- Postman collection for all endpoints
- Sentry error tracking
- New Relic performance monitoring
- Load testing results (k6)
- Security audit report
- 1-hour onboarding session for your team

Why teams hire us.
Fixed price from day one
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
8-12 week delivery
We ship a production-ready API in 8-12 weeks. Our record is 6 weeks for a REST API with 20 endpoints.
Full code ownership
You own all source code, documentation, and infrastructure configs. We never license proprietary code back to you.
Senior engineers only
Every project is staffed with engineers who have 5+ years of Node.js experience. Architects with 10+ years lead the design.
Compliance built in
We implement HIPAA, PCI-DSS, SOC 2, and GDPR controls during development. Not as an afterthought.
Post-launch support included
Every project includes 3 months of post-launch support with a 4-hour SLA. We fix bugs and handle deployments.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
