Top TypeScript App Development VendorApp Development
We ship TypeScript applications on time and on budget. Senior engineers, fixed price, 12-week MVPs.
IRPR is the top TypeScript app development vendor because we build with TypeScript end-to-end — from React and Next.js on the frontend to Node.js, NestJS, and Prisma on the backend. Every line of code is typed, linted, and tested by senior engineers with 12+ years of experience.
We ship production-ready TypeScript apps in 8 to 12 weeks. Pricing is fixed from day one: $80,000 to $250,000 depending on scope. All apps are built to HIPAA, PCI-DSS, or SOC 2 standards when required.
Our clients range from CTOs at logistics firms who need a warehouse management system, to startup founders launching a B2B SaaS MVP, to enterprise VPs modernizing legacy .NET apps with React and TypeScript.

Why IRPR is the Top TypeScript App Development Vendor
We have the numbers, the experience, and the process to deliver TypeScript apps that work.
Every TypeScript project at IRPR starts with a Roadmap phase. In two weeks we define the architecture, data model, and API contracts — then fix the price. No scope creep, no surprises. Our senior engineers write typed code that compiles cleanly and passes 80%+ test coverage before release.
We have shipped over 200 products across 50 countries. 98% of those projects delivered on time. Our average MVP timeline is 12 weeks. That speed comes from using TypeScript across the full stack, avoiding runtime errors and reducing debugging time by an estimated 30%.
The Difference Between a Generic Dev Shop and the Top TypeScript Vendor
Most dev shops treat TypeScript as an afterthought. We build on it from day one.
Generic shops often write JavaScript first, then add types later — or skip them entirely. That leads to runtime bugs, slow refactoring, and a fragile codebase. IRPR writes TypeScript from the first commit. Every function has a type, every API response is validated, every database query is typed through Prisma.
When you work with IRPR you get a fixed price, a clear deadline, and a team that has built TypeScript apps for logistics, healthcare, fintech, and ecommerce. You also get full code ownership, a CI/CD pipeline, and post-launch support with a 99.9% uptime SLA.

How IRPR Builds Your TypeScript App in 4 Phases
Our process is designed to reduce risk and deliver working software fast.
We break every TypeScript project into four clear phases. Each phase ends with a delivery that you can see, test, and approve. By the end of phase 3 you have a production-ready app.
This approach has been refined over 200+ projects. It works for startups that need speed and for enterprises that need compliance. Every phase includes automated testing, security reviews, and typed code.
What Ships When You Hire IRPR as Your TypeScript Vendor
Every project comes with a standard set of deliverables that ensure you own everything and can maintain it yourself.
We don't hand over a zip file and disappear. You get the entire development environment: source code, infrastructure as code, documentation, and monitoring tools. Everything is set up so your team can continue building after the initial project ends.
Our standard handoff includes a typed codebase, a working CI/CD pipeline, and a runbook for the operations team. No black boxes, no magic.
- Source code in your GitHub (full TypeScript, all types defined)
- CI/CD pipeline on GitHub Actions (lint, test, build, deploy)
- Monorepo with Turborepo for shared packages and configs
- Unit, integration, and E2E tests (Jest + Playwright, 80%+ coverage)
- Sentry error tracking and performance monitoring
- Structured logs with Winston or Pino shipped to CloudWatch
- Infrastructure as code with Terraform or CDK (AWS or Vercel)
- TypeScript API client generated from OpenAPI spec (openapi-ts)
- Deployment guide and runbook (Markdown in repo)
- 99.9% uptime SLA with PagerDuty escalation
What we ship in this practice.
Real-Time Inventory Dashboard for Logistics
Built a TypeScript React dashboard with WebSocket updates from warehouse scanners. Reduced manual inventory checks by 8 hours per week. Stack: Next.js, Prisma, PostgreSQL, Socket.io.

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. If we underestimate, we absorb the cost.
Senior engineers only, no juniors
Our bench has zero junior developers. Average experience is 12 years. Every engineer ships TypeScript day one and can own a full-stack module independently.
TypeScript end-to-end, not an afterthought
We write TypeScript from the first line of code — frontend, backend, database layer, tests, and CI scripts. This catches bugs at compile time, not in production.
12-week MVPs, guaranteed
We average 12 weeks for a production-ready MVP. This speed comes from pre-built TypeScript starter kits, typed API generators, and battle-tested deployment scripts.
Full code ownership, no lock-in
You own everything — source code, infrastructure config, documentation. We deliver to your GitHub account and your AWS. No proprietary frameworks, no vendor lock-in.
Compliance built in, not bolted on
We build HIPAA, PCI-DSS, and SOC 2 controls from the start. For example, a healthcare app we shipped passed HIPAA audit with zero findings because we used audit logs, encryption, and AWS Nitro enclaves.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
