Node.js API Development ConsultantsDevelopment Consultants
We build production-ready Node.js APIs in 12 weeks. Fixed pricing, no surprises.
IRPR builds custom Node.js APIs for web and mobile apps. We use Express.js, Fastify, NestJS, and connect to PostgreSQL, MongoDB, Redis, and cloud services like AWS Lambda and Firebase.
Every project ships ready for production in 8-12 weeks. Pricing starts at $80K for a full API and goes up based on complexity. We handle compliance like SOC 2, PCI-DSS, and HIPAA when needed.
We work with startup CTOs launching SaaS MVPs, product managers at mid-market companies scaling integrations, and enterprise teams needing dedicated Node.js backend consultants for specialized modules.
Types of software we ship.
REST API Development
Build RESTful APIs with endpoints optimized for performance. We use Express.js, rate limiting, and OpenAPI documentation.
GraphQL API Development
Implement GraphQL with Apollo Server for flexible data queries. Supports real-time subscriptions and federated schemas.
Microservices API Development
Design microservices with Node.js and message queues like RabbitMQ. Deploy in Docker containers on Kubernetes.
API Integration Services
Connect your Node.js API to third-party services like Stripe, Salesforce, Twilio, and Slack. Handles OAuth and webhooks.
Real-time API Development
Build real-time APIs with Socket.IO or WebSockets for chat, live dashboards, and notifications. Low latency, high concurrency.
API Security & Authentication
Implement JWT, OAuth2, and SAML authentication. Includes rate limiting, input validation, and CORS policies.
API Documentation & Testing
Auto-generate API docs using Swagger/OpenAPI. We write integration tests with Jest and automate Postman collections.
Serverless API Development
Deploy Node.js APIs as AWS Lambda functions or on Vercel. Pay-per-use, auto-scaling, and zero server management.
We build for every business type.
SaaS companies
E-commerce businesses
Fintech firms
Healthcare organizations
Real estate and proptech
Node.js API projects we deliver on time
200+ Node.js APIs shipped since 2018 with 98% on-time delivery.
Each API is built for production from day one. We follow test-driven development and deploy to CI/CD pipelines on GitHub Actions. Our average project takes 12 weeks from spec to release.
Clients include startups scaling to millions of users and enterprises modernizing legacy backends. We have built APIs for fintech, healthcare, and ecommerce industries with audit trails and compliance.
The difference between generic agencies and IRPR
Most API development projects fail due to unclear scopes and hourly billing. We fix that.
Generic agencies often start coding without a complete roadmap. They bill by the hour, making costs unpredictable. Code quality varies, and you may lose access to the source code.
IRPR gives you a fixed price after a thorough Roadmap phase. You own the code from day one. Every API is built with automated tests, monitoring, and documentation included.
- Vague estimates that grow
- Hourly billing with no cap
- No roadmap or spec in writing
- Code quality not audited
- No automated tests
- You don't own the code
- Fixed price after 2-week Roadmap
- No surprise invoices
- Detailed spec and timeline upfront
- Peer-reviewed code with CI/CD
- Automated test suite and Postman collection
- Full IP ownership and source code
Our Node.js API development process
Four phases from idea to deployed API.
Phase 1: Roadmap. We analyze your requirements, define endpoints, data models, and create a fixed-price proposal. This takes 1-2 weeks.
Phase 2: Build. Our senior engineers deliver the API in parallel sprints. You see progress weekly with live deployments to staging.
What ships with every Node.js API
Every project delivers these assets.
Your API includes everything needed to run and maintain it. No missing pieces.
- Source code in your private repository
- CI/CD pipeline with GitHub Actions
- Automated API tests using Jest and Supertest
- OpenAPI/Swagger documentation
- Postman collection with example requests
- Rate limiting and security headers configured
- Sentry error tracking and monitoring
- Deployment configuration for AWS or Docker
- Admin panel or seed data script
- 30-day post-launch support and bug fixes

Why teams hire us.
Fixed price, not hourly
Every Node.js API project gets a fixed quote after the Roadmap phase (week 2). No hourly billing, no scope creep charges. Average project is $80K-$250K.
Senior engineers only
Our team has 10+ years average experience. We use TypeScript, test-driven development, and peer review. No junior developers assigned to your API.
Production-ready from sprint 1
We deploy to staging in the first sprint. Your API includes monitoring, error tracking, and automated tests before going live.
You own everything
Full IP ownership. Source code, documentation, and deployment scripts all go into your repository. No lock-in to IRPR.
Compliance built in
We build HIPAA, PCI-DSS, SOC 2, and GDPR-compliant APIs. Our security checklist includes encryption, access controls, and audit logs.
200+ APIs delivered
Since 2018 we have shipped over 200 APIs for companies in 50 countries. 98% of projects delivered on time and within budget.
