Code Example

NestJS in Action

nestjs-demoBackend
// users.controller.ts
import { Controller, Get, Post, Body, Param, UseGuards } from '@nestjs/common';
import { ApiTags, ApiBearerAuth } from '@nestjs/swagger';
import { JwtAuthGuard } from '../auth/jwt-auth.guard';
import { UsersService } from './users.service';
import { CreateUserDto } from './dto/create-user.dto';

@ApiTags('users')
@Controller('users')
export class UsersController {
  constructor(private readonly usersService: UsersService) {}

  @Post()
  create(@Body() createUserDto: CreateUserDto) {
    return this.usersService.create(createUserDto);
  }

  @Get(':id')
  @UseGuards(JwtAuthGuard)
  @ApiBearerAuth()
  findOne(@Param('id') id: string) {
    return this.usersService.findOne(+id);
  }
}

Engagement Models

Three ways to hire NestJS developers

Pick the engagement that matches how you actually work. No multi-year contracts — scale up or down month by month.

Dedicated Developer

Most popular

Full-time NestJS engineer who reports only to you. Best for ongoing products, long-term roadmaps and teams that need a core hire without the HR overhead.

  • 40 hours / week
  • Your Jira, your repo
  • Month-to-month

Hourly / Time & Materials

Pay only for billable hours. Ideal for research spikes, code audits, or variable-load NestJS work where scope is still being discovered.

  • Weekly timesheets
  • Slack-first comms
  • No minimum commit

Fixed-price Milestones

Scoped delivery with clear milestones and acceptance criteria. Best for well-defined NestJS builds like an MVP, a migration or a specific module.

  • Scope locked upfront
