TypeScript developers write type-safe JavaScript that catches bugs at compile time instead of in production. Companies hire them to build frontend and backend systems that are easier to maintain, refactor, and scale. Here's what they can help you with when you hire through Revelo:
React & Next.js Frontend Development
Build production frontends with React and Next.js using TypeScript's full type system. Our developers write components with typed props, hooks, and API responses that make refactoring safe and onboarding new developers faster.
Node.js API Development
Design and build typed REST and GraphQL APIs on Node.js with frameworks like Express, Fastify, or NestJS. Our developers use TypeScript to enforce request/response contracts that keep your frontend and backend in sync.
Monorepo Setup & Tooling
Configure monorepos with Turborepo, Nx, or pnpm workspaces that share TypeScript types, utilities, and configs across packages. Our developers set up build pipelines that keep compile times fast even as your codebase grows.
JavaScript-to-TypeScript Migration
Incrementally migrate existing JavaScript projects to TypeScript without halting feature development. Our developers use strict-mode progression, starting with the riskiest modules and adding types where they'll catch the most bugs first.
Full-Stack Type Safety
Implement end-to-end type safety from database to UI using tools like tRPC, Prisma, and Zod. Our developers build systems where a schema change propagates type errors everywhere it matters — before anything ships.

A TypeScript developer uses the TypeScript programming language to create memorable websites and applications and superior user experiences (UX). TypeScript is a strongly typed programming language that adds static typing with optional type annotations on top of JavaScript, one of the three core technologies powering the internet. Developers often use TypeScript for large-scale app development.
These software engineers provide many advantages, such as beautiful user interfaces (UI) and streamlined front-end and back-end development. However, hiring TypeScript developers can be time-consuming and costly due to market saturation.
What Is TypeScript Development?
TypeScript is a compiled, strongly typed, and object-oriented programming language. As an open-source superset of JavaScript, TypeScript adds static typing with optional type annotations on top of JavaScript. These additions empower developers to catch and fix mistakes earlier in the software development lifecycle (SDLC). Engineers can use TypeScript on client-side (front end) or server-side (back end) web development.
TypeScript is a natural choice for developing large-scale applications. The following projects often use TypeScript:
- Web, desktop, and mobile apps
- Server-side or back-end applications
- Games
- Internet of Things (IoT) applications
- Analytics and monitoring platforms, including dashboards
- Workflow automation tools
- Embeddable application programming interfaces (APIs)
Why TypeScript Development?
TypeScript development has emerged as a keystone in modern web applications, distinguished by its ability to enhance JavaScript with type safety and object-oriented features. This augmentation is about catching errors early and making the code more readable and maintainable — a boon for any engineering team, especially those in scaling businesses. Developers can leverage TypeScript to enforce coding standards and reduce bugs that tend to slip through during runtime in plain JavaScript.
Furthermore, TypeScript's compatibility with JavaScript means it integrates seamlessly into existing projects, providing immediate value without overhauling the current ecosystem.
The versatility of TypeScript extends beyond mere error prevention. It facilitates large-scale application development by enabling better tooling support and easier refactoring. As businesses grow and their web applications become more complex, TypeScript paves the way for more scalable architecture.
Leveraging TypeScript aligns with the industry trend toward comprehensive front-end frameworks such as Angular, which natively adopts TypeScript due to its advanced features conducive to enterprise-level projects.
