Senior Node.js API Development PartnerAPI Partner
We build production-grade APIs for startups and enterprises. Get a fixed timeline and a dedicated senior team.
IRPR builds high-performance APIs using Node.js, Express.js, Fastify, and TypeScript. We handle REST, GraphQL, WebSocket, and gRPC protocols with clean, maintainable code.
Each project ships with full source code, CI/CD pipeline, monitoring dashboards, and automated tests. Typical timeline is 8-12 weeks for an MVP. Pricing ranges from $80,000 to $250,000 depending on complexity. We enforce SOC 2 and HIPAA compliance where required.
We work with CTOs at Series A startups needing a scalable API layer, engineering directors at SaaS companies migrating from monoliths to microservices, product managers launching API-first products, and enterprise architects modernizing legacy systems.
Types of software we ship.
REST API Development
Build RESTful APIs with OpenAPI specs, auto-documented endpoints, and versioning. Integrates with Express.js, Postman, and Swagger.
GraphQL API Development
Build GraphQL APIs with Apollo Server, schema stitching, and resolver patterns. Supports real-time subscriptions and efficient data fetching.
Microservices API Development
Design and build microservices architectures with Node.js, Docker, Kubernetes, and message brokers like RabbitMQ or Kafka.
WebSocket API Development
Build real-time WebSocket APIs for live updates, chat, notifications, and streaming. Uses Socket.IO, ws library, and Redis pub/sub.
Backend for Mobile Apps
Build the server-side API layer for mobile apps (iOS, Android) with REST or GraphQL, authentication (JWT, OAuth), and push notifications.
API Gateway / BFF Development
Build a Backend-for-Frontend (BFF) API gateway that aggregates multiple services and provides optimized endpoints for each client.
Third-Party API Integration
Integrate your system with third-party APIs (Stripe, Shopify, Salesforce, etc.) using Node.js adapters, caching, and error handling.
Custom Node.js API Framework
Build a custom API framework with middleware, rate limiting, logging, and health checks. Deployable on AWS Lambda or EC2 with auto-scaling.
We build for every business type.
SaaS companies
Ecommerce platforms
Healthcare organizations
Fintech companies
Media & Entertainment
Why a senior Node.js API partner matters
Building a scalable API requires deep expertise in Node.js architecture, testing, and deployment.
A junior team often delivers slow, unstable APIs that break under load. IRPR assigns 2-4 senior engineers who have shipped over 200 products across 50 countries. Each API is load-tested with k6 before release.
We use TypeScript for type safety, ESLint and Prettier for code quality, and automated CI/CD pipelines. Every endpoint is documented with Swagger and covered by unit and integration tests.
The difference between a generic dev shop and IRPR
Not all Node.js partners deliver the same quality. Here is what sets IRPR apart.
We have seen many projects that started with a cheap hourly agency and ended with broken APIs, missing documentation, and no ownership of code. IRPR takes a different approach.
We guarantee fixed price, full ownership, and a senior team that stays with you from architecture to production. No scope creep, no junior devs, no surprises.
- Hourly billing with no cap
- Junior developers rotated in
- Vague timelines and delays
- No compliance awareness
- Code held hostage until final payment
- No monitoring or post-launch support
- Fixed price with no surprises
- Dedicated senior Node.js engineers
- 8-12 week delivery guarantee
- Built-in HIPAA, PCI-DSS, SOC 2
- Full code ownership from day one
- Sentry, Datadog, and health checks set up
Our Node.js API development process
We follow a structured four-phase process to deliver a production-ready API on time.
Each phase has clear deliverables and a fixed timeline. You see progress every week and can adjust scope early.
We use agile sprints with daily standups, a shared Jira board, and bi-weekly demos. No black box.
What ships with every API project
Every Node.js API delivery includes these deliverables by default.
No hidden extras. Everything listed is included in the fixed price.
You can also request additional integrations or custom dashboards at the Roadmap phase.
- Full source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and performance monitoring
- Datadog dashboards for API metrics
- Swagger/OpenAPI documentation
- Unit and integration tests (Jest, Mocha)
- Load test reports with k6
- Dockerfile and docker-compose for local dev
- Health check endpoint and status page
- Deployment scripts for AWS or GCP
What we ship in this practice.
Real-time chat API for a social media startup

Payment gateway API for a fintech company
Developed PCI-DSS compliant payment API processing $10M/month. Achieved 99.99% uptime. Tech: Node.js, Stripe Connect, PostgreSQL, AWS Lambda.
Ecommerce product search API
Built a GraphQL search API that reduced page load time by 60%. Tech: Apollo Server, Elasticsearch, Redis cache.
Healthcare patient data API
Created HIPAA-compliant FHIR API for a telemedicine platform. Scaled to 100K patients without downtime. Tech: Node.js, Express, MongoDB, AWS HealthLake.
Microservices API for a SaaS platform
Migrated from monolith to microservices, enabling independent deployments. Reduced release cycle from 2 weeks to 2 days. Tech: Node.js, Docker, Kubernetes, Kafka.
Analytics API for a media company
Built a REST API that ingests 1TB of data daily and serves real-time dashboards. Tech: Node.js, Fastify, ClickHouse, Redis, Grafana.
Why teams hire us.
Fixed price, no hourly bills
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges.
Dedicated senior team
You get 2-4 senior Node.js engineers assigned to your project. No junior devs, no team churn during the engagement.
8-12 week MVP guarantee
We ship a production-ready API in 8-12 weeks. 98% of our projects deliver on time, and we meet that deadline.
Full code ownership
You own all source code from day one. We hand over the repo with an MIT license. No lock-in, no restrictions.
Compliance built-in
We build APIs that meet HIPAA, PCI-DSS, and SOC 2 standards. Our infrastructure is audited and we document every control.
