Need a reliable backend developer for your web application? I specialize in building secure, scalable, and maintainable backend solutions using Node.js, Express.js, and MongoDB. Whether you're starting a new project, upgrading an existing application, or fixing backend issues, I can deliver clean, efficient, and well-structured code tailored to your requirements.

My services include custom REST API development, CRUD operations, MongoDB database integration, JWT authentication and authorization, API testing with Postman, error handling, input validation, bug fixing, backend optimization, and code refactoring. I also provide API documentation and a setup guide to make deployment and maintenance straightforward.

Every project is thoroughly tested before delivery. You'll receive complete source code, a Postman collection for API testing, an example environment configuration file, and clear documentation for installation and usage. I prioritize code quality, security, performance, and maintainability to ensure your backend is reliable and easy to scale as your application grows.

Technologies I use: Node.js, Express.js, MongoDB, JavaScript (ES6+), Postman, Git, and GitHub.

I believe in clear communication, timely delivery, and providing solutions that match your business goals. Whether you need a simple API, authentication system, database integration, or a complete backend for your web application, I'm committed to delivering high-quality results with professional support throughout the project.
