I will develop custom API backend in node js express and mongodb

Need a professional Node.js backend developer?

I build fast, secure, and scalable REST APIs with Node.js, Express.js, MySQL, MongoDB, and Firebase. Whether its simple CRUD endpoints, a full backend system, or advanced third-party integrations (ERP, CRM, Stripe, Twilio, etc.), I deliver robust, production-ready solutions tailored to your needs.

My Services Include:

• Secure RESTful API development
• Database integration (MySQL, MongoDB, Firebase)
• Authentication & authorization (JWT, OAuth 2.0, session-based)
• Custom business logic & middleware
• Third-party API integrations
• Input validation, error handling, rate-limiting, CORS
• Swagger/Postman API documentation (on request)
• Clean, modular, and fully commented code

I focus on performance, scalability, and maintainable architecture. Youll get the complete source code with inline comments and a deployment-ready setup.

Lets build a backend that works perfectly for your project. Message me first so we can discuss your requirements and timeline before you order.
