Senior TypeScript Development AgencyDevelopment Agency
We build production-grade apps with TypeScript, React, and Node.js. Your MVP ships in 8-12 weeks with senior engineers only.
IRPR is a senior TypeScript development agency. We build web apps, APIs, and SaaS platforms with TypeScript, React, and Node.js. Every engineer has 10+ years of experience.
Your MVP ships in 8-12 weeks. Our fixed-price model starts at $80K and runs to $250K for complex projects. We handle compliance like HIPAA, PCI-DSS, and SOC 2.
Founders hire us to build and validate product-market fit. CTOs hire us to scale their backend with type-safe APIs. Product managers hire us to ship new features without hiring a full in-house team.

Why hire a senior TypeScript development agency
Senior TypeScript engineers reduce bugs and speed up delivery by catching errors at compile time.
TypeScript catches 15% of bugs before runtime, per a 2020 study from the University of Waterloo. IRPR has shipped 200+ TypeScript projects across all major frameworks including Next.js, NestJS, and Fastify. Our engineers wrote their first type annotations in 2015.
We run TypeScript strict mode on every project. No implicit any, no unchecked indexed access. This eliminates entire categories of runtime errors in production. Our clients see 99.9% uptime on apps we deliver.
Generic dev shop vs senior TypeScript agency
Not every agency builds apps with strict TypeScript. Here is how IRPR differs from the rest.
Generic shops often write TypeScript like JavaScript, using any everywhere. They skip tsconfig strict mode and ship code full of type escapes. This defeats the purpose of TypeScript entirely.
IRPR enforces strict type checking on every PR. We use ESLint, Prettier, and Husky pre-commit hooks to prevent type errors from reaching production. Your code stays clean even after 50+ developers touch it.
- uses any and as casts freely
- no strict mode in tsconfig
- inconsistent code style
- no automated type checks
- type errors found in QA, not CI
- hard to refactor without bugs
- strict mode enabled on day one
- no implicit any, no unchecked access
- shared ESLint and Prettier config per project
- type checks in CI with GitHub Actions
- errors caught at compile time, not runtime
- refactoring is fast and safe
How we build your TypeScript project
IRPR follows a 4-phase process that turns your idea into a production-ready app in 8-12 weeks.
Every project starts with a 1-week Roadmap phase. We audit your requirements, choose the type-safe stack, and produce a fixed-price quote. No hourly billing, no scope creep.
Then we build your MVP in 8-12 weeks using TypeScript, React, Node.js, and PostgreSQL. We deploy to AWS with CI/CD, Sentry monitoring, and automated tests. You own the code from day one.
What ships with your TypeScript app
Every project includes a full production setup, not just code.
You get source code with strict TypeScript, a CI/CD pipeline, error monitoring, and cloud infrastructure. No configuration left undone.
IRPR sets up PostgreSQL with Prisma, AWS ECS or Lambda for hosting, Sentry for error tracking, and Cloudflare for CDN. Your app is ready to handle real users from week 12.
- Source code in your private GitHub repo
- CI/CD pipeline with GitHub Actions and type checks
- Prisma ORM with PostgreSQL schema migrations
- REST or GraphQL API with Zod validation
- Sentry error and performance monitoring
- AWS infrastructure as code (CDK or Terraform)
- Unit and integration tests with Vitest or Jest
- Docker containers for local development
- Tailwind CSS design system with responsive layout
- Admin panel with role-based access control
What we ship in this practice.
SaaS dashboard for a fintech startup
IRPR built a real-time analytics dashboard with Next.js, D3.js, and WebSocket. The startup reduced report generation time from 4 hours to 12 seconds. TypeScript strict mode caught 3 null-reference bugs during development that would have crashed the app in production.
Telemedicine patient portal
A healthcare client needed a HIPAA-compliant patient portal. We built it with Next.js, Prisma, and PostgreSQL. TypeScript ensured type-safe API calls for protected health information. The app passed HIPAA audit on first submission.
Multi-vendor ecommerce platform
We developed a headless storefront with Next.js and Medusa.js. The platform handles 500+ concurrent vendors with real-time inventory sync via WebSocket. TypeScript reduced integration bugs by 40% compared to the previous JavaScript codebase.
Real estate MLS aggregation API
IRPR built a TypeScript backend with Fastify and Redis that aggregates listings from 50+ MLS feeds. The API serves 10M requests per month with 99.9% uptime. TypeScript's union types modeled complex property data without runtime validation errors.
EdTech assessment platform
A learning company needed a FERPA-compliant assessment tool. We used Next.js, Socket.io, and PostgreSQL. TypeScript enforced strict typing on student data, making audits straightforward. The platform supports 10,000 concurrent quiz takers.
Logistics route optimizer
We built a TypeScript backend with Node.js and Mapbox that optimizes delivery routes for a fleet of 200 trucks. The app reduced fuel costs by 12% and saved 8 hours of manual planning per week. TypeScript's generics modeled complex route constraints with zero runtime errors in the first 6 months.
Why teams hire us.
Senior engineers only
Every engineer on your project has 10+ years of experience and has shipped TypeScript apps for at least 5 years. No juniors, no training wheels. Your project is built by people who teach conferences, not attend them.
Fixed price from week 2
After the 1-week Roadmap phase, we give you a fixed price for the entire project. No hourly billing. No surprises. If new requests come up, we quote them separately before starting work.
TypeScript strict mode always
We enable TypeScript strict mode on every project. No implicit any, no unchecked index access, no skipLibCheck. This catches 15% of bugs before they reach production.
200+ products shipped
IRPR has delivered over 200 production apps across 50 countries. Every project uses TypeScript with React and Node.js. We have seen every edge case and know what works at scale.
Production infrastructure included
Your app ships with AWS hosting, CI/CD pipelines, Sentry error monitoring, and PostgreSQL database. You do not need to hire a DevOps person. It is all included in the fixed price.
Full code ownership
You own every line of code from day one. No licenses. No lock-in. No ongoing fees. IRPR hands over the complete codebase, infrastructure configuration, and documentation at the end of the project.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
