Senior TypeScript App Development DevelopersApp Development
You need experienced TypeScript developers who ship fast. We build your app in 8-12 weeks with a fixed price.
IRPR builds production apps with senior TypeScript app development developers. We use TypeScript across the stack: React for frontends, Node.js for APIs, Next.js for full-stack apps, and React Native for mobile. Every project ships with CI/CD, automated tests, and monitoring.
Our senior TypeScript developers deliver MVPs in 8-12 weeks with fixed pricing from $80K to $250K. We handle HIPAA, PCI-DSS, and SOC 2 compliance for regulated industries. You get full code ownership, a working app in your repo, and support after launch.
Startups hire us to validate their idea with a production-ready app. Series A/B companies hire us to rebuild their legacy frontend in TypeScript. Enterprise teams hire us to build internal tools or customer portals. We also work with agencies that need senior TypeScript developers for overflow work.

Why Senior TypeScript Developers Matter for Your App
TypeScript catches bugs before they reach production. Senior TypeScript developers ship faster because they know the language deeply.
TypeScript adoption grew by 200% in the last 3 years. 78% of new projects use TypeScript for the frontend alone. Our senior TypeScript developers have shipped over 200 apps using TypeScript across React, Node, and Next.js.
When you hire IRPR, you get developers who have worked on 50+ TypeScript projects each. They know type inference, generics, mapped types, and module augmentation. They set up strict tsconfig rules, enforce code reviews, and maintain zero-any policies.
How IRPR Compares to Generic Dev Shops
Most agencies use junior developers, bill by the hour, and miss deadlines. IRPR builds with senior TypeScript developers on a fixed price.
A generic dev shop hires 2 junior developers and 1 senior. They charge hourly and extend the timeline when scope changes. The code quality suffers and TypeScript is used as a label, not enforced.
IRPR assigns 2-3 senior TypeScript developers to every project. We deliver in 8-12 weeks on a fixed price. Your code passes strict TypeScript checks, has 90%+ test coverage, and ships with a CI/CD pipeline.
- Uses junior developers with 1-2 years of TypeScript
- Bills hourly and charges for scope creep
- Delivers in 20+ weeks with missed milestones
- No CI/CD or automated testing
- Code has 'any' types and loose linting
- No compliance support for HIPAA or PCI
- Assigns senior TypeScript engineers with 5+ years experience
- Fixed price from the Roadmap phase (week 2)
- Delivers MVPs in 8-12 weeks with 98% on-time rate
- Sets up CI/CD on GitHub Actions + Sentry monitoring
- Enforces strict TypeScript with zero-any and full coverage
- Built-in HIPAA, PCI-DSS, and SOC 2 compliance
Our Process: From Idea to Production TypeScript App
We follow four phases to turn your concept into a production-ready TypeScript app.
Every project starts with a Roadmap phase. You pay a flat $5K-$10K fee for the first 2 weeks. We produce a detailed spec, architecture, and fixed-price contract for the full build.
After you approve the Roadmap, we enter the Product phase. We work in 2-week sprints, demo every Friday, and ship the MVP in 8-12 weeks. Then we handle Release with monitoring, documentation, and handoff.
What Ships With Every TypeScript App
You get a complete, production-ready app with everything included. No hidden deliverables.
Every project includes the entire source code in your GitHub repo, a CI/CD pipeline using GitHub Actions, and automated testing with Jest and Playwright. We also set up error tracking with Sentry and performance monitoring with Datadog.
You receive detailed documentation: API endpoints, database schema, component library, and deployment instructions. All secrets and environment variables are stored securely in AWS Secrets Manager or a similar vault.
- Full source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions (lint, test, build, deploy)
- Automated tests with Jest, React Testing Library, and Playwright
- TypeScript configuration with strict mode and no-any
- Sentry error tracking with real-time alerts
- Datadog performance monitoring for API and frontend
- API documentation with Swagger or TypeSpec
- Database migration scripts and seed data
- Deployment playbook for AWS, Vercel, or Docker
- 2 weeks of post-launch support with chat channel
What we ship in this practice.
Fintech investment dashboard
A financial startup needed a real-time dashboard for advisors to view portfolios. IRPR built it with TypeScript, React, and WebSockets. The app reduced data loading time by 60% and handles 10,000 concurrent users. Stack: TypeScript, React, Node.js, PostgreSQL, Redis.
Telemedicine appointment system
A healthcare company required a HIPAA-compliant scheduling and video platform. We used TypeScript, React, WebRTC, and AWS. The system processes 5,000 appointments per week with 99.9% uptime. Stack: TypeScript, Next.js, Twilio, AWS.
SaaS rental marketplace
A startup building a peer-to-peer equipment rental marketplace needed an MVP in 10 weeks. We delivered a full-stack app with TypeScript, Next.js, Stripe, and maps integration. The platform handled 500 bookings in the first month. Stack: TypeScript, Next.js, Stripe, Google Maps API.
Ecommerce headless storefront
A fashion brand wanted a lightning-fast storefront on Shopify headless. We built it with TypeScript, Next.js, and Shopify Storefront API. Page load times dropped from 4 seconds to 0.8 seconds, increasing conversions by 25%. Stack: TypeScript, Next.js, Shopify, Tailwind CSS.
Real estate MLS search portal
