Hire an Expert Node.js API Development TeamAPI Development
We build production-ready Node.js APIs in 8-12 weeks. Senior engineers, fixed pricing, no surprises.
IRPR builds production Node.js APIs using Express.js, Fastify, and NestJS. We design REST and GraphQL endpoints with PostgreSQL, Redis caching, and RabbitMQ message queues. Every API gets load tested with k6 before release.
Our expert Node.js API development team ships a fully functional MVP in 8-12 weeks. Pricing is fixed at $80K-$250K per project. We comply with HIPAA, PCI-DSS, and SOC 2 standards as required. You own the code from day one.
CTOs at Series A startups hire us to build their core API infrastructure without hiring a full internal team. Product managers at mid-market companies use us to launch new features on a tight timeline. Founders scaling a SaaS platform come to us for reliable, secure backends.
Types of software we ship.
RESTful API
Standard REST endpoints for CRUD operations, with OpenAPI 3.0 documentation and automated testing via Supertest.

Why hire an expert Node.js API development team from IRPR
Our team has shipped 200+ production APIs for clients in 50 countries.
Every engineer at IRPR has at least 8 years of experience building distributed systems. We do not hire juniors. Our average engineer has 12 years of experience. We use Node.js with TypeScript, Express.js or Fastify, and PostgreSQL. Every API is deployed with Docker and tested for 99.9% uptime.
We start with a two-week Roadmap phase where we define the API contract, schema, and endpoints. You get a fixed price before any code is written. No hourly billing. No scope creep. Our 200+ past projects include APIs for fintech startups processing $50M monthly and healthcare platforms serving 100K patients.
The difference between generic shops and IRPR's expert Node.js API team
Not all development teams are built the same. Here's what sets IRPR apart.
A generic agency might assign your Node.js API project to a junior developer with 2 years of experience. They often use outdated Express patterns and skip load testing. You pay by the hour and watch the timeline slip. You do not own the code unless you pay extra.
IRPR assigns a senior engineer with 10+ years of Node.js experience. We write TypeScript, integrate a CI/CD pipeline with GitHub Actions, and run load tests with k6. You get a fixed price before work begins. You own the source code and intellectual property from day one.
- Junior developers with 2 years of experience
- Hourly billing with undefined scope
- No load testing or API contract
- Code ownership requires extra fee
- No compliance documentation
- Average project runs 4 months overdue
- Senior engineers with 10+ years experience
- Fixed price from the Roadmap phase
- k6 load testing and OpenAPI docs included
- Full code ownership from day one
- HIPAA, PCI-DSS, SOC 2 compliance ready
- 8-12 week delivery, 98% on-time
How our expert Node.js API development team delivers your project
Our process follows the Idea-Roadmap-Product-Release framework.
We start with a 1-week Idea phase where we define your API's purpose, users, and endpoints. You get a scope document with a clear feature list.
In the Roadmap phase (week 2), our senior engineers build a detailed API contract using OpenAPI 3.0. We set up the database schema in PostgreSQL, configure Redis caching, and create a CI/CD pipeline. You receive a fixed price quote based on this blueprint.
What ships with every Node.js API from IRPR
Every project includes these deliverables by default. No hidden fees.
You get more than just code. Every API comes with documentation, tests, deployment scripts, and monitoring. We also include a 30-minute weekly sync call with the lead engineer. You can see the progress in real time on our shared Slack channel.
Our compliance packages are built into the project. If you need HIPAA, we add audit logging and encryption at rest. If you need PCI-DSS, we configure tokenization for credit card data. These are not upcharge items – they are part of the engineering process.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- OpenAPI 3.0 documentation
- k6 load test scripts and results report
- Deployment scripts for AWS ECS or Kubernetes
- PostgreSQL schema with migration files
- Sentry error tracking configured
- Datadog monitoring dashboard
- Unit tests with 90%+ coverage
- 1 month post-launch support
What we ship in this practice.
Payment processing API for a fintech startup
IRPR built a RESTful API with Express.js, PostgreSQL, and Stripe Connect that handles $50M in monthly transactions. The API includes idempotency keys, webhook verification, and automatic retry logic. Reduced payment failures by 40%.
Patient data API for a telemedicine platform
We built a HIPAA-compliant API using NestJS and DynamoDB for a telemedicine app serving 100K patients. The API encrypts PHI at rest and in transit. Includes audit logging and role-based access. Passed HIPAA audit on first try.
Inventory management API for a retail chain
IRPR developed a GraphQL API with Apollo Server and Redis for a chain of 200 stores. The API updates inventory in real time across all locations. Reduced stockouts by 30% and saved the client $500K in lost sales annually.
Subscription billing API for a SaaS company
We built a Node.js API with Fastify and Stripe that handles recurring billing, prorations, and multi-tenant data isolation. The API processes 10K subscription changes per day. Cut billing errors by 95%.
MLS data API for a real estate platform
IRPR created a RESTful API that aggregates MLS data from 50+ sources. Built with Express.js and PostgreSQL, the API normalizes property listings and caches results in Redis for sub-50ms response times. Increased listing accuracy by 99%.
Student enrollment API for an edtech platform
We built a FERPA-compliant API using NestJS and MongoDB for a university portal serving 50K students. The API handles course registration, grade retrieval, and financial aid data. Reduced enrollment processing time from 2 days to 15 minutes.
Why teams hire us.
Fixed price, not hourly billing
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a line of code.
Senior engineers only, no juniors
Our team averages 12 years of experience. Every engineer has shipped at least 10 production APIs. We never outsource or staff juniors. You talk directly to the engineer building your API.
Full code ownership from day one
You own the source code, documentation, deployment scripts, and all IP from the start. No licensing fees, no royalties. We push code to your GitHub repo. You can take it anywhere.
Compliance built in, not bolted on
We build HIPAA, PCI-DSS, and SOC 2 compliance into the architecture from the first sprint. No separate security audit needed. Our APIs pass third-party compliance reviews on the first attempt.
8-12 week delivery guarantee
Our process from Idea to Release takes 8-12 weeks. We have a 98% on-time delivery rate across 200+ projects. Each sprint delivers working endpoints you can test immediately.
Dual-shore coverage with overlap hours
Our team operates from New York and Eastern Europe with 6 hours of daily overlap for US clients. You get real-time communication during your business hours. Response time is under 2 hours.
Idea → Roadmap → Product → Release.
