Best Node.js API Development StudioAPI Development
We build production-ready Node.js APIs for your product. Get a fully documented, tested API in 12 weeks with senior Node.js engineers.
IRPR builds Node.js APIs using Express, Fastify, Prisma, PostgreSQL, Redis, and Docker. Every API is designed for scalability and tested with Jest.
Our projects ship in 12-14 weeks with fixed pricing between $80K and $250K. We meet HIPAA, PCI-DSS, and SOC 2 compliance standards.
Startup CTOs hire us for MVP APIs that handle 10K requests per second. Enterprise architects migrate monolithic backends to Node.js microservices. Product managers build real-time data pipelines. Founders launch SaaS products with a secure, documented API.
Types of software we ship.
REST API
Standard RESTful endpoints with OpenAPI 3.0 docs. Uses Express.js with middleware for auth and rate limiting.
GraphQL API
Single endpoint with Apollo Server. Resolvers fetch from PostgreSQL, Redis cache, and third-party services.
gRPC API
High-performance gRPC services with Protocol Buffers. Ideal for inter-service communication in microservice architectures.
WebSocket API
Real-time bidirectional communication using Socket.IO or ws. Supports live dashboards and chat features.
Microservices Gateway
Central API gateway using Kong or Express Gateway. Routes requests to multiple Node.js services with authentication.
Backend for Frontend (BFF)
Dedicated API layer per frontend (web, mobile). Aggregates data from internal services and transforms responses.
Real-Time Data API
Streams data via SSE or WebSockets from Kafka or Redis Pub/Sub. Used for live stock prices and IoT telemetry.
Internal Service API
Private APIs for internal microservices with gRPC or REST. Logs all calls to Elasticsearch for observability.
We build for every business type.
Healthcare
Fintech
SaaS
Ecommerce
Logistics
Why the best Node.js API development studio ships faster
IRPR uses proven processes and senior engineers to deliver Node.js APIs on time and on budget.
Our average delivery is 12 weeks from kickoff to production. We use a fixed-price Roadmap phase (week 2) to lock scope and cost, so there are no surprises. Every API includes OpenAPI documentation, Postman collections, and CI/CD pipelines.
With 200+ products shipped across 50 countries, our teams know how to handle rate limiting, caching, database connection pooling, and horizontal scaling out of the box. We audit every API for security and compliance before launch.
Generic dev shops vs. IRPR: the real difference
Many agencies promise Node.js APIs but deliver incomplete, buggy code with no documentation.
Generic shops often use junior developers, lack fixed pricing, and skip CI/CD. You get a codebase that works locally but fails under load. Documentation is an afterthought.
IRPR assigns senior Node.js engineers only. We write unit tests (Jest), integration tests, and load tests (k6) before shipping. Every API comes with a deployment guide and monitoring setup in Sentry and Datadog.
- No fixed pricing per project
- Unclear delivery timeline
- Junior developers on your code
- No OpenAPI documentation
- No CI/CD pipeline included
- No post-launch support
- Fixed price from Roadmap phase (week 2)
- 12-week delivery guarantee
- Senior Node.js engineers only (7+ years)
- OpenAPI 3.0 docs by default
- CI/CD pipeline (GitHub Actions + Docker)
- Dedicated project manager and post-launch support
Our 4-phase Node.js API development process
We build your API in four transparent phases with clear milestones and deliverables.
Phase 1 (Discovery + Roadmap) takes 2 weeks. We define endpoints, data models, and third-party integrations. You get a fixed price and timeline.
Phase 2 (API design + prototype) builds the first endpoints with a live Swagger UI. Phase 3 (development + testing) adds all endpoints, unit tests, and load tests. Phase 4 (deployment + monitoring) goes to production with CI/CD and dashboards.
Everything that ships with your Node.js API
You own the full deliverable set, from source code to deployment pipelines.
We hand over the complete project so your team can maintain and extend it immediately. No black boxes, no locked-in proprietary tools.
Every project includes production-ready infrastructure code, monitoring, and on-call setup. Your team gets access to the same dashboards we use.
- Source code in your GitHub/GitLab repo
- OpenAPI 3.0 specification (YAML/JSON)
- Postman collection with example requests
- CI/CD pipeline on GitHub Actions
- Docker Compose and Dockerfile for each service
- Sentry error tracking and Datadog monitoring
- Jest unit tests with 90%+ coverage
- k6 load test scripts for endpoints
- Deployment guide with step-by-step instructions
- One-hour post-launch handover call
What we ship in this practice.
Real-Time Payment Processing API
Built a REST API for a fintech startup that processes 5000 transactions per minute. Reduced latency from 400ms to 80ms using Redis caching and Express.js clustering. Tech stack: Node.js, Express, PostgreSQL, Redis, Stripe API.
Patient Data Exchange API
Developed a HIPAA-compliant GraphQL API for a telemedicine platform. Replaced manual file transfers with a secure data exchange that handles 10K patient records daily. Tech stack: Node.js, Apollo Server, Prisma, PostgreSQL, FHIR integration.
Ecommerce Product Catalog API
Created a REST API for an ecommerce brand with 200K SKUs. Added real-time inventory updates via WebSockets, reducing cart abandonment by 15%. Tech stack: Node.js, Fastify, PostgreSQL, Elasticsearch, Nginx.
SaaS Subscription Management API
Delivered a microservice gateway for a B2B SaaS platform. Handles user auth, plan upgrades, and usage tracking for 50K active subscribers. Tech stack: Node.js, Kong Gateway, Redis, MongoDB, Stripe Integration.
MLS Property Data API
Built a GraphQL API that unifies data from 5 MLS providers for a real estate startup. Developers now fetch property details in one query instead of 5 separate calls. Tech stack: Node.js, Apollo Server, PostgreSQL, Redis, AWS Lambda.
IoT Device Management API
Engineered a WebSocket API for a logistics firm to monitor 15K GPS trackers in real time. Reduced dashboard load time from 12 seconds to 2 seconds using event streaming. Tech stack: Node.js, Socket.IO, Kafka, MongoDB, Docker.
Why teams hire us.
Fixed price, not hourly
Every Node.js API project gets a fixed quote during the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Senior engineers only
IRPR hires only senior Node.js developers with 7+ years experience. No juniors, no offshore teams. Your code is written by engineers who have built APIs at scale.
12-week delivery guarantee
We ship your API in 12 weeks on average. If we miss the date, we discount the next phase. Our process has delivered 200+ projects on time.
Full code ownership
You own every line of code we write. Source code goes into your private GitHub repo from day one. No licensing fees, no lock-in.
OpenAPI-first design
Every API ships with an OpenAPI 3.0 specification and a Postman collection. Your team can start integrating the same day we deploy.
Post-launch support included
Every project includes 30 hours of post-launch support. We monitor uptime, fix bugs, and help your team take over the codebase.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
