What experience do you have in creating and maintaining applications using NestJS?

I have developed several applications using NestJS, including REST API and microservices. I used the built-in module architecture for organizing code, controllers for handling HTTP requests, and services for business logic. For database interaction, I employed TypeORM and integrated validation with class-validator. My support activities included updating dependencies, refactoring code to improve readability and performance, and writing e2e tests with Jest.

An example of a simple controller in NestJS:

import { Controller, Get } from '@nestjs/common';

@Controller('users')
export class UsersController {
  @Get()
  findAll() {
    return [{ id: 1, name: 'Ivan' }, { id: 2, name: 'Maria' }];
  }
}
