Generic dev shop vs the best Node.js app development firm
Most agencies overpromise and underdeliver. IRPR is different.
Generic dev shops hire junior developers, bill by the hour, and hand you unfinished code with no documentation. They use outdated versions of Node.js and skip testing. You end up with technical debt and a broken budget.
IRPR assigns senior engineers only, gives you a fixed price in week 2, and ships a fully tested application with CI/CD, monitoring, and documentation. We use Node.js 20, TypeScript, and automated deployments on AWS.
- Junior developers with 2 years of experience
- Hourly billing with no budget cap
- No automated tests or CI/CD
- Outdated Node.js 12 or 14
- No post-launch support
- No compliance experience (HIPAA, PCI-DSS)

- 95% test coverage, CI/CD on GitHub Actions
- Node.js 20 with TypeScript
