Senior Node.js API Development FirmAPI Development
We build production-grade Node.js APIs in 8-12 weeks. Fixed price, senior engineers only, zero scope creep.
IRPR is a senior Node.js API development firm that builds secure, scalable REST and GraphQL APIs for SaaS platforms, mobile backends, and enterprise integrations. Our engineers use Node.js 22, TypeScript, Fastify, Prisma ORM, and Redis to deliver sub-50ms response times and 99.9% uptime.
Every project ships in 8-12 weeks with a fixed price between $80K and $250K. We handle compliance out of the box: HIPAA for healthcare APIs, PCI-DSS for payment APIs, SOC 2 for enterprise SaaS. Source code is yours from day one.
Companies hire us when they need senior Node.js API development: CTOs who need an MVP for investor demos, engineering leaders with a legacy API they want to rebuild in Node.js, and product managers who require a dedicated API team for a new platform. We replace the hiring headache with a flat-fee engagement.

Senior Node.js API Development Firm: What We Deliver
Every API ships with a consistent stack, automated testing, and production monitoring.
IRPR uses Node.js 22, TypeScript, PostgreSQL 16, Redis 7, and Docker. We write unit tests with Jest (90%+ coverage), integration tests with Supertest, and deploy via GitHub Actions to AWS ECS or Fly.io. Each API includes OpenAPI 3.0 documentation and a Postman collection.
We manage infrastructure as code using Terraform and Pulumi. Logs go to Datadog or CloudWatch. Error tracking via Sentry. Alerts on p95 latency over 200ms. This is the default, not an upgrade.
Why IRPR is Different from a Generic Node.js Agency
Generic dev shops hire junior devs and bill by the hour. IRPR sends senior engineers at a fixed price.
Most agencies assign a mix of junior and mid-level developers. You pay for onboarding, learning curve, and scope creep. Unclear requirements become change orders. Code quality drops as deadlines slip.
IRPR assigns 2-4 senior Node.js engineers (7+ years experience) who work in 2-week sprints. You get a fixed price in the Roadmap phase (week 2). No hourly billing. No surprise invoices. The code is yours, running on your cloud account from day one.
- Junior and mid-level developers
- Hourly billing with no cap
- Scope creep = change order
- No dedicated PM
- Code stays in agency repo
- Handoff after launch, no support
- Senior engineers only (7+ yrs)
- Fixed price from week 2
- Roadmap locks scope before dev
- Dedicated tech lead
- Source code in your repo
- Sentry + Datadog monitoring included
How We Build Your Node.js API in 12 Weeks
Four stages from idea to production, with clear deliverables at each step.
Week 1-2 (Idea): We align on goals, map data models, and define the API contract using OpenAPI 3.0. You get a spec review, cost estimate, and a fixed-price proposal.
Week 3-8 (Roadmap + Product): Sprints 1-3 build the core endpoints, auth, database schema, and CI/CD pipeline. Every sprint ends with a deployable API and a demo.
Every Node.js API Ships With These Deliverables
You get a production-ready API, not a proof of concept.
No hand-waving. Every project includes source code, infrastructure, monitoring, and documentation. You own everything from day one.
We configure CI/CD on GitHub Actions, deploy to AWS or Fly.io, and set up Datadog or Sentry for observability. Postman collections and OpenAPI docs are auto-generated.
- Source code and full git history in your GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions and Docker
- Infrastructure as code (Terraform) for AWS ECS or Fly.io
- OpenAPI 3.0 specification and Swagger UI
- Postman collection with request examples
- Unit tests (Jest) and integration tests (Supertest)
- Sentry error tracking and performance monitoring
- Datadog or CloudWatch dashboard for latency and error rates
- Secrets management via AWS Secrets Manager or GitHub encrypted secrets
- One-year security patch and dependency update support

Why teams hire us.
Fixed price from week 2, not hourly
Every project gets a fixed quote in the Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the cost before a single line of code is written.
Senior engineers only, no juniors
We assign engineers with 7+ years of Node.js experience. No junior developers learning on your dollar. The average IRPR engineer has shipped 10+ production APIs.
Source code is yours day one
All code is written in a repo you own from the first commit. No license restrictions, no black box. You can walk away at any time with your full API.
Compliance built in, not bolted on
We handle HIPAA, PCI-DSS, SOC 2, and FERPA from day one. Database encryption at rest, TLS 1.3, audit logging, and role-based access control are part of the default stack.
12-week timeline, not 6 months
Most agencies quote 6-9 months for the same scope. Our 2-week sprints and senior team deliver a production API in 8-12 weeks. We have a 98% on-time record.
Post-launch support for 12 months
Every project includes one year of security patches, dependency updates, and bug fixes. We don't disappear after the final demo. Your API stays healthy.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
