About this service

Summary

I offer professional backend development services using Node.js, Express, and MongoDB to build fast, secure, and scalable web applications. From RESTful API development to authentication (JWT, OAuth) and database integration, I deliver clean, well-documented, and production-ready backends. My goal is to help startups and businesses launch reliable systems that grow with their users.

What's included

  • RESTful API development

    I will design and implement API routes that allow your application to Create, Read, Update, and Delete data. Custom endpoints will also be built based on your project requirements.

  • MongoDB Database Integration with Mongoose Schemas

    I will connect your backend to a MongoDB database, define structured schemas with Mongoose, and ensure efficient data handling and validation.

  • Authentication System (JWT, Google OAuth, or Passport.js)

    I will implement secure login and signup systems using JSON Web Tokens (JWT). For advanced needs, I can also integrate social login with Google OAuth or Passport.js.

  • Role-Based Access Control (Admin/User Permissions)

    I will set up user roles (e.g., Admin, Moderator, User) so that different users have different levels of access to your system.

  • Error Handling & Request Validation

    I will add proper error handling and input validation to ensure your backend is secure, reliable, and protected against bad data and common vulnerabilities.

  • Postman/Insomnia API Documentation

    I will provide a Postman or Insomnia collection so you can easily test all API endpoints with clear instructions.

  • Deployment Support (Heroku, Render, or Vercel Backend Setup)

    I will guide you through or set up deployment so your backend is live and accessible online.

  • Well-Structured, Production-Ready Codebase

    I will follow best practices (MVC/modular architecture, reusable code, comments) to ensure your backend is scalable, maintainable, and easy for other developers to work on.
