Why companies choose a senior TypeScript app development agency
Senior engineers write code that lasts.
Most agencies assign junior devs to save cost. Senior TypeScript engineers cost more per hour but finish faster and leave less technical debt. IRPR only hires engineers with 10+ years of experience. Our code passes strict linting, has 95%+ test coverage, and uses TypeScript strict mode.
TypeScript catches bugs at compile time, not runtime. This alone reduces production incidents by 30% according to a Stripe study. Our team has deployed over 200 apps across 50 countries with 99.9% uptime.
Generic dev shop vs Senior TypeScript agency
Not all TypeScript development is equal.
Many agencies claim TypeScript expertise but assign junior developers. They set up slow CI pipelines, skip code reviews, and deliver untestable spaghetti code. The result: a fragile app that takes months to refactor.
IRPR assigns senior engineers to every project. We deliver clean, typed code with automated tests, CI/CD, and Sentry monitoring. Your code is yours from day one.
- Junior developers writing loosening code
- No strict TypeScript config
- Sparse test coverage

- No monitoring setup
- Code ownership unclear
- Senior engineers only, 10+ years avg
- TypeScript strict mode enforced
- 95%+ test coverage
- GitHub Actions CI/CD in 2 weeks
- Sentry + Datadog monitoring
- Full code ownership from start
