Why IRPR is the best TypeScript development firm
We have shipped 200+ TypeScript projects across 50 countries with a 98% on-time rate.
Our senior engineers have an average of 10+ years of experience. Every developer writes type-safe code, maintains test coverage above 80%, and deploys to production within the first sprint. We use TypeScript 5.x with strict mode enabled on every project.
We follow a four-phase process: Idea, Roadmap, Product, Release. The Roadmap phase takes one week and delivers a fixed price quote, a technical architecture document, and a sprint plan. No cost overruns, no scope creep.
How we differ from other TypeScript agencies
Most dev shops bill hourly and change scope mid-project. We do not.
Generic agencies often assign junior developers to your project and charge you for their learning curve. They use vague estimates and add line items for every change. You end up paying double the original quote.
IRPR assigns senior engineers only. We give you a fixed price after the one-week Roadmap phase. If you add features, we quote them separately before starting. No surprises, no hourly billing.
- Junior developers with 2-3 years experience
- Hourly billing with no cap
- Scope creep charges after every meeting
- No type safety - plain JavaScript
- Manual deployment, no CI/CD
- No automated testing
- Senior engineers with 10+ years average experience
- Fixed price after 1-week Roadmap phase
- Clear change order process with quotes
- TypeScript strict mode on every project
- CI/CD pipeline with GitHub Actions on day 1
- Automated testing with 80%+ coverage
Our TypeScript development process
We follow a repeatable four-phase process that de-risks every project.
Every project starts with a discovery call where we define the core problem and success metrics. In the Idea phase, we align on the product vision and target users. This takes 3-5 days.
The Roadmap phase produces a fixed price quote, a technical architecture document, and a sprint-by-sprint plan. You know exactly what you are getting and how much it costs before we write a line of code.
What ships with every TypeScript project
Every project includes a production-ready codebase, not a prototype.
When we deliver a TypeScript project, you get more than working code. You get a fully configured development environment, automated tests, and a deployment pipeline. Your team can start contributing on day one.
We also provide documentation for every API endpoint, database schema diagrams, and a runbook for common operations. No black boxes, no knowledge gaps.
- Source code in your private GitHub repo
- TypeScript strict mode configuration
- CI/CD pipeline with GitHub Actions
- Automated unit tests with Jest (80%+ coverage)
- API documentation with Swagger or GraphQL schema
- Database schema migration scripts
- Deployment configuration for AWS or GCP
- Sentry error tracking and Datadog monitoring
- Environment variable management with dotenv
- One-page runbook for common operations
