TypeScript
Development
Type-safe development for scalable codebases.
TypeScript is our default choice for all JavaScript projects. It significantly reduces runtime errors, improves developer experience, and makes large codebases maintainable. We use TypeScript with React, Node.js, NestJS, and Next.js.
