Backend API Development

We build production-grade backend APIs with NestJS or Node.js. Authentication, authorization, database design, validation, error handling, and comprehensive documentation.

The Problem

Building a backend from scratch takes weeks and it's easy to get architecture wrong. Bad API design haunts you for years with tech debt and scaling issues.

Our Solution

We build clean, well-structured APIs using NestJS — the most production-ready Node.js framework. Proper architecture from day one means less refactoring later.

What You Get

TypeScript

Type-safe codebase with NestJS modules and decorators

Auth Built-in

JWT authentication with role-based access control

Validated

Request validation with DTOs and class-validator

Documented

Swagger/OpenAPI docs auto-generated from code

How It Works

Requirements

We define endpoints, data models, and business logic

2

Architecture

We design the module structure, auth, and database schema

3

Development

We build the API with full validation and error handling

4

Delivery

We deploy, document, and walk you through the codebase

Frequently Asked Questions

Why NestJS?

NestJS provides enterprise-grade architecture out of the box — dependency injection, modules, guards, interceptors. It's the most structured Node.js framework and scales well with team size.

REST or GraphQL?

REST for most projects — simpler, better caching, more tooling. GraphQL when you have complex data relationships and mobile clients that need flexible queries.

Do you include database design?

Yes. We design the Prisma schema with proper relations, indexes, and migrations. Database design is a core part of API development.

Can you build on top of an existing API?

Yes. We can extend, refactor, or optimize existing NestJS/Node.js APIs. We review the codebase first to understand the existing patterns.
