Why choose IRPR for TypeScript development
We measure success by shipped products, not billable hours.
IRPR has shipped 200+ TypeScript applications across healthcare, fintech, and ecommerce. Our engineers average 10+ years of experience and write TypeScript daily.
Every project includes a 12-week roadmap, fixed pricing, and a dedicated QA engineer. We maintain 99.9% uptime on production apps and 98% on-time delivery.
We build differently than generic dev shops
Our process eliminates scope creep and surprise invoices.
Generic shops start with hourly billing and a vague timeline. They often skip TypeScript strict mode and ship untyped code that breaks in production.
IRPR starts with a 2-week Roadmap phase where we document every API, database schema, and UI screen. You get a fixed price and a shared TypeScript repo from day one.
- Hourly billing with no cap
- Unclear timeline (6+ months)
- Mixed language code (JS / TS)
- No CI/CD or monitoring setup
- No compliance certifications
- Code ownership often disputed
- Fixed price locked in week 2
- 12-week MVP delivery guarantee
- 100% TypeScript strict mode
- CI/CD on GitHub Actions, Sentry, Vercel
- HIPAA, PCI-DSS, SOC 2 ready
- Full source code ownership
Our TypeScript development process in 4 phases
We follow a proven path from idea to launch.
Every project starts with a 2-week Roadmap. We align on architecture, database schema, and feature scope before writing a single line of code.
The Product phase delivers a shippable MVP every 2 weeks. Release includes automated tests, CI/CD, and deployment to your cloud account.
What ships with every TypeScript project
You get production-grade infrastructure, not just code.
- Source code in your Git repository
- CI/CD pipeline on GitHub Actions
- Sentry error tracking and monitoring
- Prisma ORM with Postgres migrations
- Unit tests with Jest (80%+ coverage)
- API documentation with Swagger or tRPC
- Deployment scripts for Vercel or AWS
- 30-minute onboarding video for your team
- 30-day post-launch bug fix window
- TypeScript strict mode enabled

Why teams hire us.
Fixed price, not hourly hours
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges.
Senior TypeScript engineers only
Our team averages 10+ years of experience. Every engineer writes TypeScript daily and passes a strict code review before joining a project.
TypeScript from day one to deploy
We use strict mode, no any, and full type coverage. This catches bugs at compile time, not runtime. Our production error rate is under 0.1%.
Compliance built in, not bolted on
We support HIPAA, PCI-DSS, and SOC 2 in the standard stack. No separate compliance project needed. We've shipped 12 HIPAA-compliant apps.
Async-first, global team
We work across 50+ countries using overlap hours (9 AM - 1 PM Eastern). You get daily progress updates and a weekly demo without scheduling pain.
