Why Choose a Professional Node.js App Development Company
A professional node.js app development company like IRPR brings senior engineers, proven processes, and compliant infrastructure.
Generic freelancers often deliver inconsistent code. IRPR assigns a team of 2-4 senior Node.js engineers who have built 200+ production apps. Every line of code is reviewed, tested, and deployed with zero-downtime strategies. We use TypeScript, ESLint, and Prettier from day one.
You get a dedicated product manager, a tech lead, and QA engineer. We run 2-week sprints with daily standups. Code is stored in your private GitHub repository. We use Sentry for error tracking and Datadog for performance monitoring. All deployments go through CI/CD pipelines with automated tests.
How IRPR Differs from Other Node.js Development Companies
IRPR is a professional node.js app development company that guarantees quality and speed with fixed pricing.
Most agencies charge by the hour and stretch timelines. IRPR quotes a fixed price after a 1-week Roadmap phase (week 2). You know the exact cost and timeline before development starts. No surprises, no scope creep, no hourly billing.
We also enforce compliance from the start. Our infrastructure is SOC 2 audited. For healthcare clients, we build HIPAA-compliant data storage and audit logs. For fintech, we follow PCI-DSS encryption standards. Every project ships with a security checklist.
- Hourly billing - costs balloon
- Junior developers on your account
- No compliance documentation
- Unclear ownership of code
- Long handoff delays
- No monitoring after launch
- Fixed price per project
- Senior Node.js engineers only
- SOC 2, HIPAA, PCI-DSS ready
- Full intellectual property transfer
- Same team from start to finish
- 24/7 monitoring with Datadog and Sentry
Our Process for Building Node.js Applications
IRPR follows a four-phase process to turn your idea into a production Node.js app.
We start with a 1-week Roadmap phase. You pay a flat $2,500 for a detailed plan: user stories, architecture diagrams, API contracts, and a fixed price quote. If you proceed, the Roadmap fee is deducted from the total.
Development runs in 2-week sprints. We deploy to a staging environment by sprint 2. You see real progress every 14 days. After 8-12 weeks, you have a production-ready MVP with CI/CD, monitoring, and documentation.
What Ships with Every Node.js Project
IRPR delivers more than code. Every engagement includes the following by default.
You own everything: source code, documentation, CI/CD pipelines, and deployment scripts. No hidden fees. No royalties. No monthly retainers.
Our delivery package includes a post-launch support period of 30 days. If you find a bug or need a small adjustment, we fix it at no extra charge.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions with automated tests
- Sentry error tracking and Datadog performance monitoring
- API documentation with Swagger/OpenAPI 3.0
- Deployment scripts for AWS ECS, Lambda, or DigitalOcean
- Load testing report with Artillery
- Security audit checklist (OWASP Top 10)
- Post-launch support for 30 days
- Admin dashboard for non-technical users (if required)
- Full tech stack documentation (DB schema, environment vars, runbooks)
What we ship in this practice.
SaaS Analytics Dashboard Backend
