Top TypeScript App Development FirmApp Development
We build production-grade apps with TypeScript, React, and Node.js. Fixed price, no surprises, shipped in 8-12 weeks.
IRPR is a top TypeScript app development firm. We use TypeScript across the full stack: Next.js for web, React Native for mobile, Node.js for APIs, and NestJS for backend services. Every project ships with strict typing, automated tests, and CI/CD pipelines.
We deliver a fully functional MVP in 8-12 weeks. Pricing is fixed and starts at $80K for a standard web app, $120K-$250K for mobile or multi-platform apps. All code is yours, all secrets are managed, and we handle HIPAA, PCI-DSS, or SOC 2 compliance as needed.
Founders hire us to ship a validated product fast. Engineering leaders hire us to offload a complex TypeScript module. CTOs hire us to rebuild legacy JavaScript apps with TypeScript for reliability. Product managers hire us to add TypeScript-based features without growing their team.

Why choose a top TypeScript app development firm
TypeScript reduces runtime errors by up to 40% compared to plain JavaScript. Here is what that means for your project.
TypeScript catches bugs at compile time, not in production. Our projects use strict mode, noImplicitAny, and exhaustive switch checks. This means fewer surprises during deployment and less time spent debugging.
Every app we ship includes a type-safe API layer. We use tRPC or GraphQL codegen so the frontend and backend share the same types. When you change a database schema, the compiler tells you exactly where to update the UI.
How IRPR is different from other TypeScript agencies
Most firms bill hourly and change scope. We do not.
Generic dev shops often start with a vague estimate and bill by the hour. They change scope mid-project, and the code quality drops as deadlines slip. You end up with a half-finished app and no clear ownership.
IRPR gives you a fixed price after a 2-week Roadmap phase. We specify every feature, every integration, and every compliance requirement before we write a line of code. You know the cost and timeline upfront.
- Hourly billing with no cap
- Scope creep without change orders
- No TypeScript strict mode
- No automated testing
- Code ownership unclear
- Delivery timeline slips
- Fixed price from day 1
- Scope locked after Roadmap phase
- TypeScript strict mode enforced
- 100% test coverage on critical paths
- Full code ownership transferred
- 8-12 week guaranteed delivery
Our TypeScript app development process
Four phases from idea to production. Each phase has a clear output and a fixed price.
Phase 1 is the Idea validation. We review your concept, market, and technical constraints. You get a feasibility report and a high-level estimate within 1 week.
Phase 2 is the Roadmap. We write detailed user stories, design the data model, and choose the stack. You get a fixed price quote and a Gantt chart. Phase 3 is the Build. We ship the MVP in 8-12 weeks with daily standups and weekly demos. Phase 4 is the Release. We deploy to production, set up monitoring, and hand over the code.
What ships with every TypeScript project
Every deliverable includes these assets. No hidden extras.
You get the entire source code in your own GitHub repository. The code is fully typed with TypeScript strict mode, linted with ESLint, and formatted with Prettier. We include a README with setup instructions and architecture diagrams.
We also ship a CI/CD pipeline on GitHub Actions, a staging environment on AWS or Vercel, and a production deployment with auto-scaling. Monitoring is set up with Sentry for errors and Datadog for performance. You get admin access to all services.
- Source code in your GitHub repo
- CI/CD pipeline on GitHub Actions
- TypeScript strict mode configuration
- ESLint and Prettier setup
- Automated unit and integration tests
- API documentation with Swagger or tRPC
- Staging and production environments on AWS
- Sentry error tracking
- Datadog performance monitoring
- Admin credentials and access guide
What we ship in this practice.
SaaS B2B platform for a fintech startup
Built a multi-tenant subscription management app with Next.js, NestJS, PostgreSQL, and Stripe. Reduced customer onboarding time from 3 days to 2 hours. TypeScript ensured type safety across payment webhooks.

Ecommerce checkout for a D2C brand
Created a headless checkout with Next.js, Medusa, and Stripe. TypeScript ensured type-safe cart and payment flows. Conversion rate improved by 18% after launch.
Data dashboard for a logistics company
Built an interactive dashboard with Cube.js, Recharts, and TypeScript. Dispatchers can monitor fleet performance in real time. Reduced manual reporting work by 20 hours per week.
AI chatbot for a real estate agency
Developed a chatbot with LangChain, OpenAI, and TypeScript. It answers buyer questions and schedules showings. Lead response time dropped from 4 hours to 30 seconds.
Why teams hire us.
Fixed price from day one
Every project gets a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. You know the total cost before we write a line of code.
TypeScript strict mode on every project
We enforce noImplicitAny, strictNullChecks, and exhaustive switch checks. This catches bugs at compile time and reduces production incidents by 40%. Every pull request is type-checked.
8-12 week MVP delivery
We ship a fully functional MVP in 8-12 weeks. Our average is 11 weeks. You get a deployable product with real users, not a prototype or a mockup.
Full code ownership
You own all source code, documentation, and infrastructure configuration. We transfer everything to your GitHub organization at the end of the project. No licenses, no royalties.
Compliance built in
We have shipped HIPAA, PCI-DSS, and SOC 2 compliant apps. Our TypeScript codebase includes audit logging, encryption at rest, and role-based access control by default.
Senior engineers only
Our team averages 10+ years of experience. Every engineer writes TypeScript daily. We do not outsource or use junior developers. You work directly with the people building your app.
