Top TypeScript App Development ConsultantsConsultants
We build production-grade TypeScript apps in 12 weeks. Fixed price, senior engineers, zero fluff.
IRPR is a team of senior TypeScript app development consultants. We build web apps, mobile apps, and APIs using Next.js, React Native, Node.js, and TypeScript — with PostgreSQL, Prisma, GraphQL, and tRPC as our default stack. Every project ships with automated tests, CI/CD, and Sentry error tracking.
Our typical engagement runs 12 weeks from kickoff to release. Pricing is fixed, starting at $80K for an MVP and scaling to $250K for full production systems. We comply with HIPAA, PCI-DSS, and SOC 2 standards, and we own the code — you get full IP.
Founders who need a technical co-founder hire us to validate an idea. Engineering leads who need to scale fast hire us to ship a feature that their internal team can't. CTOs who want an external audit of their TypeScript architecture hire us to review and rebuild.

Why hire top TypeScript app development consultants?
TypeScript reduces bugs, speeds up refactoring, and makes onboarding new engineers 3x faster than plain JavaScript.
IRPR has shipped 200+ TypeScript applications since 2016. We use strict TypeScript with noImplicitAny, strictNullChecks, and exactOptionalPropertyTypes enabled by default. Every pull request passes ESLint, Prettier, and a test suite with 90%+ coverage.
Our clients see 40% fewer runtime errors in production compared to their previous JavaScript codebases. We also set up TypeScript path aliases, shared types between frontend and backend, and automated type generation from Prisma schemas.
Generic dev shop vs top TypeScript consultants
Not all agencies treat TypeScript as a first-class language. The difference shows in code quality, speed, and long-term maintainability.
We have seen codebases from shops that used any everywhere, turned off strict checks, and shipped type errors to production. That is not consulting. That is a mess.
IRPR writes TypeScript the way it should be written: strict mode, no casting abuse, proper generics, and domain-driven folder structure. We also set up a shared types package so your frontend and backend never disagree on shapes.
- uses 'any' liberally to ship fast
- no type sharing between frontend and backend
- no unit tests for type validation
- no CI pipeline for type checking
- no code review for TypeScript patterns
- delivers a codebase that is hard to maintain
- strict TypeScript from day one
- shared types package (Prisma + GraphQL)
- 90%+ test coverage with Vitest
- CI pipeline with type checking and linting
- senior engineer code review every PR
- ship a repo that your team can extend
Our TypeScript consulting process
We follow a 4-phase process that turns your idea into a live, testable application in 12 weeks.
Phase 1 is the Roadmap (week 1-2). We scope the full system, write user stories, and define the data model in Prisma. You get a fixed price quote and a Gantt chart.
Phase 2 is the Build (weeks 3-8). We code in 2-week sprints with daily standups and a demo at the end of each sprint. You see real commits, real PRs, and real progress.
What ships with every TypeScript project
No black box. You get everything you need to run, maintain, and extend the application yourself.
We never leave you with a zip file of code. Every project includes a fully configured development environment, CI/CD pipelines, and operational dashboards.
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline on GitHub Actions with type checking, linting, and test runs
- Sentry error tracking configured with alerting
- PostgreSQL database with Prisma schema and migrations
- Swagger or GraphQL playground for API testing
- Docker Compose setup for local development
- Automated unit tests (Vitest) with 90%+ coverage
- Stripe integration for payments (if needed)
- Auth0 or Clerk authentication setup
- 1-hour handover call and written documentation
What we ship in this practice.
Fintech dashboard with real-time data
Built a React/Next.js dashboard for a financial analytics startup. TypeScript strict mode caught type mismatches between real-time WebSocket data and chart components. Reduced data rendering errors by 60% and shipped in 10 weeks. Tech stack: Next.js, Recharts, WebSocket, PostgreSQL, Prisma.
Healthcare patient portal
Developed a HIPAA-compliant patient portal for a midwest clinic chain. Used TypeScript with shared types between the Next.js frontend and Express backend. Reduced patient data entry time by 8 hours per week. Tech stack: Next.js, Express, TypeScript, Auth0, AWS RDS, Sentry.
SaaS subscription billing platform
Built a multi-tenant billing platform for a B2B SaaS company. TypeScript union types and generics prevented invalid billing states. Platform handles 10,000+ transactions per month with 99.9% uptime. Tech stack: Next.js, tRPC, Stripe, Clerk, Prisma, PostgreSQL.
Ecommerce marketplace with Algolia search
Created a headless ecommerce marketplace for a luxury goods retailer. TypeScript strict mode ensured type safety between product catalog API and Algolia sync. Search latency dropped to under 50ms. Tech stack: Next.js, Commerce Layer, Algolia, Stripe, TypeScript, Vercel.
Real estate MLS integration app
Built a TypeScript app that synced MLS listings to a custom CRM. Used Prisma for type-safe database queries and Zod for runtime validation of MLS data. Integration saved each agent 4 hours per week on data entry. Tech stack: Next.js, Prisma, Zod, PostgreSQL, Auth0, Stripe.
AI chatbot for customer support
Developed a TypeScript-based AI chatbot for a travel booking startup. Used LangChain and OpenAI API for natural language understanding, and Pinecone for vector search. Chatbot resolved 35% of support tickets without human intervention. Tech stack: Next.js, LangChain, OpenAI, Pinecone, TypeScript, Stripe.
Why teams hire us.
Fixed price, not hourly
Every engagement gets a fixed price during the Roadmap phase (week 2). No hourly billing, no time tracking, no surprises. You know the cost before we write a line of code.
Senior TypeScript engineers only
Every engineer at IRPR has 8+ years of experience. No juniors. No offshore contractors. You work directly with the person writing the code.
Typesafe from database to UI
We use Prisma for type-safe databases, tRPC for type-safe APIs, and TypeScript for the frontend. Type mismatches never reach production.
Compliance built in
We handle HIPAA, PCI-DSS, and SOC 2 compliance as part of the build. No retrofitting. No additional cost.
Full IP ownership
You own every line of code. No license fees. No hidden terms. We sign a work-for-hire agreement before the project starts.
From zero to production in 12 weeks
Our average timeline is 12 weeks from kickoff to production release. We have shipped over 200 products on time, 98% of projects met their deadlines.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
