Scalable backend Node.js systems.
We build high-performance backend systems, RESTful APIs, and microservices using Node.js, Express, NestJS, and TypeScript for enterprise-grade scalability.
// NestJS Controller with Decorators
import { Controller, Get, Post, Body, Param } from '@nestjs/common';
import { UsersService } from './users.service';
import { CreateUserDto } from './dto/create-user.dto';
@Controller('users')
export class UsersController {
constructor(private readonly usersService: UsersService) {}
@Get(':id')
async findOne(@Param('id') id: string) {
return this.usersService.findOne(id);
}
@Post()
async create(@Body() createUserDto: CreateUserDto) {
return this.usersService.create(createUserDto);
}
}NestJS & Express Architecture
Building structured, maintainable APIs with NestJS's modular architecture. Dependency injection, decorators, and middleware pipelines enforce clean separation of concerns across your entire backend.

}Frequently Asked
NestJS provides a structured, opinionated architecture with built-in dependency injection, decorators, and modules. It enforces clean code patterns that scale with your team, while Express remains available under the hood for flexibility. For enterprise projects, NestJS significantly reduces technical debt.
We use horizontal scaling with Docker containers orchestrated by Kubernetes, combined with message queues for async workloads. Database connection pooling, Redis caching, and CDN offloading handle read-heavy traffic. Auto-scaling policies respond to CPU and request-rate thresholds in real time.
TypeScript catches type errors at compile time, provides IDE autocompletion, and makes refactoring safe. With Prisma's generated types and tRPC's end-to-end type safety, bugs are caught before code reaches production. Teams move faster with fewer runtime errors.
Yes. We follow a strangler fig pattern — incrementally migrating endpoints behind an API gateway while keeping your existing system running. Database migrations are handled with zero downtime, and we maintain backward compatibility throughout the transition.
