NestJS freelancers
NestJS is a progressive Node.js framework for building efficient, reliable and scalable server-side applications. Built with TypeScript, it leverages the power of JavaScript while offering strong typing and a mature, object-oriented architecture. This allows for better code organisation, maintainability, and testability compared to traditional Express.js applications.
If you're looking to build robust APIs, microservices, or web applications, NestJS freelancers can provide the expertise you need.
What to look for in NestJS freelancers
When hiring a NestJS freelancer, look for demonstrable experience in building and deploying production-ready applications. A strong understanding of TypeScript, JavaScript, and Node.js fundamentals is crucial. Experience with related technologies like databases (PostgreSQL, MongoDB), testing frameworks (Jest, Supertest), and DevOps practices (Docker, CI/CD) are also highly valuable.
Key skills and qualities to look for include:
- Proven experience with NestJS and TypeScript
- A strong understanding of backend development principles
- Familiarity with testing frameworks and DevOps practices
- Good communication and collaboration skills
