Why choose an expert TypeScript app development firm
TypeScript reduces bugs by up to 40% compared to plain JavaScript, according to industry studies.
IRPR has shipped over 200 TypeScript apps across healthcare, fintech, SaaS, and ecommerce. Every project uses strict TypeScript configuration with no implicit any. Our codebases are statically typed end-to-end, from database queries to React components.
We enforce type safety in CI/CD pipelines using ESLint and Prettier. Every pull request runs type checks before merging. This means fewer runtime errors and faster onboarding for new developers. Our clients report 50% fewer production incidents after switching to TypeScript.
How we differ from generic development shops
Most agencies charge by the hour and hand you half-finished code. IRPR does the opposite.
Generic dev shops often lack TypeScript expertise. They write any types, skip strict mode, and produce code that is hard to maintain. Their projects run over budget because scope is unclear.
IRPR gives you a fixed price after a 2-week Roadmap phase. We write strict TypeScript with full test coverage. You get a deployable app with CI/CD, monitoring, and documentation included.
- Hourly billing with no cap
- No TypeScript expertise
- Loose type safety
- No CI/CD setup
- No monitoring or error tracking
- Code ownership unclear
- Fixed price after Roadmap phase
- Senior TypeScript engineers only
- Strict TypeScript with full type coverage
- CI/CD pipeline included (GitHub Actions)
- Sentry error tracking in every app
- Full code ownership transferred
Our TypeScript app development process
We follow a 4-phase process that turns your idea into a live app in 12 weeks.
Phase 1 is the Roadmap. In 2 weeks we define the full scope, tech stack, and fixed price. You get a detailed document with user stories, wireframes, and a delivery timeline.
Phase 2 is Product. Over 8-10 weeks we build the MVP with weekly demos. You see working code every Friday. Phase 3 is Release. We deploy to production, set up monitoring, and run load tests. Phase 4 is optional ongoing support.
What ships with every TypeScript app
Every project includes more than just code. You get a complete production setup.
We do not hand you a zip file and walk away. Every app comes with a fully automated deployment pipeline, error tracking, and performance monitoring. Your team can start contributing on day one.
All code is owned by you. We transfer the GitHub repository, domain, and cloud accounts. You get a handover document with architecture diagrams, API docs, and runbooks.
- Source code in your private GitHub repo
- CI/CD pipeline on GitHub Actions
- Sentry error tracking configured
- Automated tests (unit + integration)
- Swagger/OpenAPI documentation
- Deployment to AWS, GCP, or Azure
- SSL certificate and custom domain
- Database backups and monitoring alerts
- Performance and load test results
- Handover document with architecture diagrams

Senior TypeScript engineers only
Every engineer on your project has 5+ years of TypeScript experience. We do not outsource or use junior developers. Your code is written by experts who contribute to open source TypeScript projects.

You get a fixed quote after the 2-week Roadmap phase. No hourly billing, no surprise invoices, no scope creep charges. The price you see is the price you pay.
12-week MVP delivery
We ship a production-ready MVP in 12 weeks or less. Our average is 10.5 weeks across 200+ projects. You get a working app, not a prototype.
Full code ownership
You own every line of code from day one. We transfer the GitHub repo, cloud accounts, and domain at the end of the project. No licensing fees, no lock-in.
Built for compliance
We have delivered TypeScript apps for HIPAA, PCI-DSS, SOC 2, and FERPA environments. Our codebase includes audit logging, encryption, and access controls out of the box.
