Senior Node.js App Development ConsultantsDevelopment Consultants
Hire senior Node.js consultants who ship production apps in 8-12 weeks. Fixed pricing, no hourly billing.
IRPR builds production Node.js apps using Express, NestJS, and Fastify. We deploy on AWS Lambda, ECS, and Kubernetes with CI/CD pipelines in GitHub Actions.
Every project ships in 8-12 weeks at a fixed price between $80,000 and $250,000. Our apps comply with HIPAA, PCI-DSS, and SOC 2 standards.
Startup CTOs hire us to build their MVP in 10 weeks. Enterprise engineering managers use us for mission-critical microservices. Product directors bring us in for platform rewrites.

What senior Node.js consultants deliver
Every engagement produces production-ready code, not prototypes.
Our consultants write clean, typed Node.js with TypeScript. We follow a strict branch-based workflow with code review by two senior engineers. All code is tested at unit, integration, and e2e levels using Jest and Playwright.
You get a running app on staging within the first 4 weeks. We deploy to production by week 10. Every release includes monitoring with Sentry and Datadog.
IRPR vs generic development shops
Most shops bill hourly and staff juniors. We do the opposite.
Generic dev shops often assign junior Node.js developers who need constant supervision. They charge for learning time and miss deadlines. Code quality drops and tech debt piles up.
IRPR assigns only senior Node.js engineers with 8+ years of experience. We work asynchronously across time zones but guarantee 4 hours of daily overlap with your team. Fixed price means no surprises.
- juniors or mixed teams
- hourly billing, scope creep
- unclear code ownership
- no compliance expertise
- average delivery 6+ months
- hand-off with minimal docs
- 100% senior Node.js engineers
- fixed price from $80k to $250k
- full source code ownership
- HIPAA, PCI-DSS, SOC 2 experience
- 8-12 week delivery
- comprehensive docs and CI/CD
Our 4-phase Node.js consulting process
From idea to production in 12 weeks or less.
We start with a 2-week Roadmap phase where we define the architecture, choose the tech stack, and give you a fixed quote. No commitment beyond the Roadmap.
Then we build the MVP in 8-10 weeks, ship to production, and hand over with full documentation. Post-launch support is available at a monthly retainer.
What ships with every Node.js engagement
You get more than code. You get a production system.
Every IRPR delivery includes infrastructure-as-code (Terraform), automated tests, and observability. Your team can take over immediately.
We document all API endpoints with Swagger and include a Postman collection. The deployment pipeline is fully automated so you can push changes with one command.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and AWS CodeDeploy
- TypeScript Node.js codebase with linting and formatting
- Unit and integration tests (80%+ coverage)
- API documentation via Swagger/OpenAPI
- Postman collection for all endpoints
- Docker Compose for local development
- Terraform modules for AWS infrastructure
- Sentry error tracking and Datadog monitoring
- One month of post-launch support included
What we ship in this practice.

Content Management API
Developed a headless CMS backend with Node.js, Express, and PostgreSQL. Supports versioning, webhooks, and media uploads to S3. Powers 50 content editors.
Why teams hire us.
Fixed price, not hourly
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 cost before we build.
Senior engineers only
All our consultants have 8+ years of Node.js experience. No juniors, no outsourcing. They work from the US, Canada, and Europe with 4-hour daily overlap with your time zone.
Compliance ready
We have built Node.js apps for HIPAA-covered entities, PCI-DSS Level 1 merchants, and SOC 2 type II certified platforms. Our codebase includes audit logs and encryption by default.
Full source code ownership
You own every line of code. We put it in your GitHub repo from day one. No licenses, no IP disputes. You can terminate and continue with your team at any time.
2-week kickoff
We can start within 2 weeks of signing. The first 2-day workshop defines the entire roadmap. You see a working prototype by week 4.
Asynchronous-first, not remote chaos
We communicate via GitHub issues and Slack. Daily standups are async, but we guarantee 4 hours of real-time overlap for code reviews and decisions. No meetings overhead.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
