About this gig
Looking for a professional Node.js backend developer?
I specialize in building fast, secure, and scalable REST APIs using Node.js, Express.js, MySQL, MongoDB, and Firebase.
Whether you need simple CRUD endpoints, a full backend system, or advanced third-party integration (like ERP, Oracle, or CRM systems), I deliver clean, robust, and production-ready solutions tailored to your exact needs.
What I Offer:
- Clean & secure RESTful API development
- ️ Database integration (MySQL, MongoDB, Firebase)
- Authentication systems (JWT, OAuth 2.0, session-based)
- ️ Business logic & custom middleware setup
- Third-party API integrations (Stripe, Twilio, etc.)
- Swagger or Postman API documentation (on request)
- Input validation, error handling, rate-limiting, and CORS
- Modular & scalable code with comments for maintainability
I prioritize clean architecture, performance optimization, and easy-to-extend code. You'll receive full source code with detailed inline comments and deployment-ready structure.
Lets build something scalable and efficient message me before ordering to align on your requirements and timeline.
