Experienced TypeScript App Development DevelopersApp Development
We build production TypeScript apps in 8-12 weeks. Fixed price, senior engineers only, full ownership.
IRPR builds TypeScript apps for web, mobile, and backend. We use React, Next.js, Node.js, Express, NestJS, and TypeORM. Every project starts with a TypeScript-first architecture for type safety and maintainability.
We ship MVPs in 8-12 weeks. Pricing is fixed: $80K-$250K per project. All code is owned by you. We follow HIPAA, PCI-DSS, and SOC 2 compliance when needed.
CTOs hire us to build scalable apps without hiring a full in-house team. Startup founders hire us to validate ideas with a production-grade MVP. Product managers hire us to ship features their internal team lacks capacity for.

Why TypeScript matters for your app development
TypeScript catches bugs at compile time, not runtime. That means fewer production issues and faster development cycles.
We have shipped 200+ TypeScript apps. Every app uses strict TypeScript configuration with noImplicitAny and strictNullChecks enabled. This catches null reference errors and type mismatches before they reach users. Our team has been writing TypeScript since version 2.0 in 2016.
TypeScript reduces debugging time by an average of 40% compared to plain JavaScript. With our fixed-price model, you pay for features, not for fixing runtime bugs. We use ESLint with TypeScript rules and Prettier for consistent code formatting across the entire codebase.
The difference between hiring freelancers and IRPR
Freelancers disappear. Agencies overcharge. IRPR gives you a senior team with fixed pricing and full ownership.
Most TypeScript developers you find on Upwork or Toptal work alone. They have no backup, no code review, no DevOps. When they get sick or take another client, your project stalls. IRPR assigns a team of 3-5 senior engineers who all know your codebase.
We use a Roadmap phase (week 2) to lock scope and price. You get a fixed quote, a timeline, and a list of deliverables. No hourly billing, no scope creep, no surprises. Every project includes CI/CD, error tracking with Sentry, and monitoring with Datadog.
- hourly billing with no cap
- junior or mid-level developers
- no code ownership guarantee
- no compliance expertise
- no DevOps or CI/CD pipeline
- no post-launch support
- fixed price from Roadmap phase
- senior engineers only (8+ years)
- full code ownership in your repo
- HIPAA, PCI-DSS, SOC 2 ready
- CI/CD with GitHub Actions and Sentry
- 12-week post-launch support included
How we build your TypeScript app in 4 phases
We move from idea to production in 8-12 weeks. Each phase has a clear deliverable and a fixed price.
Our process is designed for speed and transparency. You see working software every 2 weeks. We use GitHub for code, Linear for tasks, and Slack for daily communication. Every phase ends with a demo and a sign-off.
Phase 1 (Idea) is a 2-day discovery workshop. Phase 2 (Roadmap) is a 1-week planning sprint that produces a fixed quote. Phase 3 (Product) is the 6-10 week build. Phase 4 (Release) includes deployment, testing, and handoff.
What ships with every TypeScript app
You get more than code. Every project includes infrastructure, testing, and documentation.
We don't just hand over a GitHub repo. We set up the entire development and production environment. Your team can start contributing on day one after launch.
Every project includes a CI/CD pipeline, automated tests, and monitoring. You own all of it. No recurring license fees, no vendor lock-in.
- Source code in your private GitHub repo
- CI/CD pipeline using GitHub Actions
- Automated tests with Jest and Cypress
- Error tracking with Sentry
- Performance monitoring with Datadog
- Deployment on AWS, Vercel, or your own infrastructure
- API documentation with Swagger or Postman
- Database schema and migration scripts
- 12 weeks of post-launch support

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 total cost before we write a line of code.
Senior engineers only
Every engineer on your team has 8+ years of experience. No juniors, no offshore interns. We interview for TypeScript expertise, system design, and communication skills.
Full code ownership
You own every line of code. We put it in your GitHub repo from day one. No proprietary frameworks, no license fees, no vendor lock-in.
Compliance built in
We build HIPAA, PCI-DSS, and SOC 2 compliant apps. Our team has shipped apps for healthcare, fintech, and enterprise clients. We handle audits and documentation.
8-12 week MVPs
We ship production-grade MVPs in 8-12 weeks. You get a working app with authentication, payments, and a database. Not a prototype, not a demo, a real app.
12 weeks of post-launch support
After launch, we stay on for 12 weeks. We fix bugs, add small features, and help your team take over. No cold handoff, no abandoned code.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
