Hire TypeScript Developers — Full-Stack React + NestJS
Reading time: 2 minutes.
TypeScript Full-Stack Development — React, NestJS, React Native
The case for TypeScript isn’t about syntax — it’s about shared contracts across the stack. When your frontend, backend, and mobile app all speak the same typed language, you eliminate an entire class of integration bugs and make onboarding new developers faster.
CimpleO runs a TypeScript-first stack. Our developers don’t switch contexts between a JavaScript frontend and an untyped backend — it’s React + NestJS + React Native, all TypeScript, end to end.
What We’ve Built
ZeroDark — Shipyard Operations Platform — React (TypeScript) frontend, NestJS backend. HR management, crew scheduling, task assignment, and role-based access for a maritime company. Full TypeScript stack with shared type definitions between client and server.
Hoppn Food Delivery — TypeScript, NestJS, React Native. Progressive Node.js backend with typed API contracts consumed by both the web admin and the React Native mobile app. MangoPay, Twilio, Google Maps integrations — all typed.
Mertim Marketplace — NestJS + React Native marketplace. Complex domain model (sellers, buyers, couriers, payments) — TypeScript strict mode caught dozens of edge-case bugs before they hit production.
Why Full-Stack TypeScript Matters in Practice
Shared types across the API boundary. Define a DTO once in NestJS, import it in React. No more frontend bugs caused by a backend field rename that was never communicated.
Safer refactoring. When you rename a method or change a function signature, the compiler tells you everywhere it’s used — across the whole codebase, not just the file you’re editing.
Better onboarding. A developer joining the team reads types instead of documentation that may be out of date.
NestJS specifically. Angular-inspired architecture with decorators, dependency injection, and a module system. Our team has written about NestJS module design and Swagger integration in depth — this isn’t surface-level familiarity.
Engagement Models
Full-stack TypeScript team: React frontend + NestJS backend + React Native mobile, delivered together. One team, one codebase language, one point of contact.
Backend only: NestJS API, database schema, auth, third-party integrations.
Frontend only: React SPA or Next.js consuming your existing API. TypeScript-first, tested.
Migration: JavaScript → TypeScript for existing codebases. Incremental, low-risk, with measurable strictness targets.
Stack
- Frontend: React 18+, Next.js, TypeScript strict mode
- Backend: NestJS, Node.js, TypeScript, Prisma / TypeORM
- Mobile: React Native CLI, TypeScript
- State: Redux Toolkit, Zustand, React Query
- API: REST, GraphQL, WebSockets
- Auth: JWT, OAuth2, Passport.js
- Deployment: Docker, AWS, GCP, Vercel, Railway
