Node.js API Development StudioAPI Development
We build production-grade Node.js APIs in 8-12 weeks. Fixed price, senior engineers, no surprises.
IRPR builds custom Node.js APIs for SaaS platforms, fintech apps, and enterprise systems. We use Express, Fastify, Apollo GraphQL, and Postgres to deliver APIs that handle 10K+ requests per second.
Every Node.js API ships within 8-12 weeks at a fixed price between $80K and $250K. We handle compliance like SOC 2 (SaaS), HIPAA (healthcare), and PCI-DSS (fintech). You get full source code and CI/CD pipelines.
Founders who need a fast MVP to raise seed funding. CTOs who want to replace a flaky legacy API. Product managers launching a new data product. Enterprise teams requiring a compliant, scalable backend.
Types of software we ship.
REST API Development
Stateless APIs with OpenAPI 3.1 docs, rate limiting, and auth (JWT/OAuth2). Used by SaaS dashboards.
GraphQL API Development
Flexible schemas with Apollo Server, DataLoader for N+1 prevention, and real-time subscriptions.
WebSocket & Real-Time API
Low-latency WebSocket servers for chat, live location, or collaborative tools. Built on ws and Socket.io.
Serverless API (AWS Lambda)
Auto-scaling APIs on Lambda + API Gateway with cold-start optimization using Lambda Layers.
Microservices API Gateway
Central gateway (Kong, Express Gateway) routing to Node.js microservices with circuit breakers.
Backend for Frontend (BFF)
Dedicated Node.js services that aggregate data from multiple backends for a specific client (React, mobile).
Event-Driven & Streaming API
APIs consuming Kafka or RabbitMQ events. Node.js workers for async processing and data pipelines.
Internal / Private API (RPC)
gRPC-based APIs with Protobuf schemas for high-throughput internal services. Used in fintech and logistics.
We build for every business type.
Companies needing PCI-DSS compliant APIs
Organizations requiring HIPAA-compliant APIs
Businesses building storefront and order APIs
Product teams launching multi-tenant APIs
Operators needing real-time tracking APIs
Node.js API Development by the Numbers
We measure everything. Here is what 200+ shipped Node.js APIs have taught us.
Our average Node.js API project ships in 10 weeks. The fastest REST API went live in 6 weeks. We maintain a 98% on-time delivery rate across all projects.
99.9% uptime is standard for our APIs deployed on AWS/GCP with multi-region redundancy. Our largest API handles 50M requests per month on two t3.medium instances.
Generic Dev Shop vs. IRPR: The API Difference
Not all Node.js teams are equal. Here is what separates a pro studio from a freelance hire.
A generic developer might copy a boilerplate and call it done. IRPR applies 12 years of Node.js production experience to every API.
We enforce consistent patterns: request validation (Joi), structured logging (Winston), error handling middleware, and CI/CD with GitHub Actions.
- No written API contract; endpoints change mid-project
- Mixed Node.js versions; no linting or formatting
- No rate limiting; first production load brings it down
- No monitoring; you debug endpoints at 3 AM
- No test coverage; every deploy is risky
- Hourly billing; costs balloon without accountability
- OpenAPI 3.1 spec frozen before coding starts
- Consistent Node 20 LTS with ESLint + Prettier
- Built-in rate limiting and DDoS protection
- Sentry + Datadog monitoring from day one
- 90%+ test coverage with Jest + Supertest
- Fixed price locked in Roadmap phase
How We Build Your Node.js API in 8-12 Weeks
Our four-phase process turns your idea into a live API endpoint.
Phase 1 (Idea Week 1): We map every endpoint, data model, and third-party integration. You get an OpenAPI spec and a fixed price contract.
Phase 2 (Roadmap Week 2): Senior engineers break the work into 2-week sprints. You see the Gantt chart and estimated milestones.
Every Node.js API Includes These Deliverables
You own everything. No lock-in. No black boxes.
We ship more than code. Every API project comes with documentation, infrastructure code, and runbooks.
You can deploy locally, on your own cloud, or with our DevOps team. The choice is yours.
- Full source code in your GitHub repo
- CI/CD pipeline with GitHub Actions
- OpenAPI 3.1 specification (YAML/JSON)
- Docker Compose for local development
- Sentry error tracking and performance monitoring
- Structured logging (Winston) with log levels
- Rate limiting (1000 req/min default, configurable)
- JWT / OAuth2 authentication middleware
- Database migrations (Postgres/Prisma)
- Deployment playbook and runbook
What we ship in this practice.
Fintech Payment Orchestration API
Built a REST API that routes transactions across 5 payment gateways (Stripe, Adyen, Square). Reduced payment failure rate by 40%. Tech stack: Express, Postgres, Redis, PCI-DSS compliant.
Healthcare Telehealth GraphQL API
GraphQL API for a telemedicine platform covering doctor scheduling, video rooms, and EHR integration. Handles 2K concurrent users during peak hours. Tech stack: Apollo Server, Prisma, PostgreSQL, HIPAA compliant.
Ecommerce Headless CMS API
Serverless REST API for a multi-brand ecommerce site. Aggregates product data from 3 third-party ERPs. Reduced page load time by 60%. Tech stack: AWS Lambda, API Gateway, DynamoDB, Stripe.
SaaS Analytics Dashboard API
WebSocket API that streams real-time analytics to a React dashboard. Processes 50K events/min with <100ms latency. Tech stack: Socket.io, Node.js, Kafka, ClickHouse.
Logistics Fleet Tracking API
gRPC API for GPS tracking of 2,000 delivery vehicles. Cut database write latency by 70% using Protobuf and sharded Postgres. Tech stack: gRPC-Web, Node.js, Postgres, RabbitMQ.
Real Estate MLS Aggregation API
REST API that ingests and normalizes listings from 12 MLS sources (IDX, RETS). Reduced data inconsistency by 95%. Tech stack: Express, Node.js, MongoDB, Redis cache.
Why teams hire us.
Senior Node.js engineers only
Our team averages 10 years of Node.js experience. Every developer has shipped production APIs at scale. No juniors, no outsourcing.
Fixed price from week 2
After the Roadmap phase, you get a fixed price contract. No hourly billing, no scope creep charges. If we miss a commitment, we reimburse 10%.
Compliance built in, not bolted on
We have delivered HIPAA-compliant APIs for 8 healthcare clients and PCI-DSS APIs for 6 fintech companies. SOC 2 is standard for SaaS APIs.
Full ownership, no lock-in
You get the entire source code, Docker files, and CI/CD scripts. Deploy anywhere you want. We never host anything on our own infrastructure.
Production monitoring included
We set up Sentry, Datadog, and PagerDuty during the first sprint. You see error logs and performance metrics from day one.
8-12 week delivery guarantee
Our average API ships in 10 weeks. We have delivered in 6 weeks for clients with tight launch deadlines. Written commitment in every contract.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
