Senior TypeScript App Development FirmApp Development
We ship TypeScript apps in 8-12 weeks. Fixed price, no hourly billing, full code ownership.
IRPR is a senior TypeScript app development firm. We build web apps, mobile apps, and backend services using TypeScript, Node.js, React, Next.js, React Native, and PostgreSQL. Every project starts with a 2-week Roadmap phase to define scope and price.
We ship production apps in 8-12 weeks. Pricing is fixed from the start: $80K-$250K depending on complexity. Our senior engineers have delivered apps for healthcare (HIPAA), fintech (PCI-DSS), and SaaS (SOC 2) clients across 50+ countries.
Companies hire us when they need a reliable TypeScript team: founders with a funded idea who need an MVP fast, CTOs who want to offload a critical feature without hiring in-house, and product managers who need a second engineering squad that ships on time.

Why a Senior TypeScript App Development Firm Matters
Hiring a senior TypeScript firm means you get engineers who have shipped 200+ products and understand production realities.
Junior developers write TypeScript that compiles but breaks in production. Senior engineers write TypeScript that scales. At IRPR, every engineer has 8+ years of experience and has built apps used by millions. We use strict TypeScript configurations, exhaustive type checks, and automated tests to catch errors before deploy.
Our team has built apps for clients in fintech, healthcare, and SaaS. One client reduced their API error rate by 95% after we rewrote their backend in TypeScript with proper error handling. We deploy on AWS or Vercel with CI/CD pipelines that run type checking and unit tests on every commit.
How IRPR Beats Generic Development Shops
Most agencies sell TypeScript but assign juniors. IRPR assigns senior engineers and gives you fixed pricing.
Generic shops promise senior developers but deliver mid-level talent. They bill hourly and scope creeps. IRPR writes a fixed-price contract in week 2 after the Roadmap phase. You know the cost and timeline before we write a line of production code.
We use TypeScript for everything: frontend, backend, infrastructure as code (Pulumi), and database migrations. This means fewer bugs and faster onboarding if you take the code in-house. Every project includes full CI/CD, error monitoring with Sentry, and deployment runbooks.
- assigns juniors with 2 years of experience
- bills hourly with no cap
- uses any language, no TypeScript focus
- no dedicated QA; tests are manual
- delivers code with loose types or any
- no CI/CD pipeline; you handle deployment
- all engineers are senior (8+ years)
- fixed price agreed in week 2
- 100% TypeScript — strict mode enabled
- automated tests and QA in every sprint
- no any types; fully typed everywhere
- CI/CD with GitHub Actions and Sentry
Our Process: From Idea to TypeScript App in 8-12 Weeks
We follow a four-phase process that de-risks your project and delivers a production-grade app.
Every engagement starts with a 2-week Roadmap phase. Our senior engineers analyze your requirements, design the architecture, and write a detailed specification. You get a fixed price and a delivery date before any development begins.
The Product phase is 4-8 weeks of iterative development. We ship a working MVP at the end of week 6. The Release phase includes load testing, security audit, and production deployment. We hand over full source code and documentation.
What Ships with Every TypeScript App
Every project includes production essentials that most agencies charge extra for.
We don't just send you a zip file. You get a fully configured deployment pipeline, error tracking, and documentation. Our standard package ensures your app is production-ready from day one.
For enterprise clients, we also include a security audit (OWASP Top 10), performance testing with k6, and a compliance checklist (SOC 2, HIPAA, or PCI-DSS as applicable).
- Source code in your private GitHub/GitLab repo
- CI/CD pipeline with GitHub Actions or GitLab CI
- Sentry error monitoring and performance tracking
- Automated test suite (unit, integration, e2e with Playwright)
- Dockerized development environment (docker-compose)
- API documentation (OpenAPI / Swagger)
- Deployment runbook for AWS, Vercel, or your cloud
- Database schema migrations (Prisma or TypeORM)
- Environment configuration (dotenv, secrets manager)
- README with setup instructions and architecture overview
