About this gig

Need a reliable Node.js backend or REST API for your application?

I will build custom backend systems using Node.js and Express.js, with clean API architecture and functionality designed around your project requirements.

Whether you need a new REST API, backend functionality for a web or mobile application, database integration, authentication, or improvements to an existing Node.js project, I can help.

What I can build:

  • Node.js backend applications
  • Express.js REST APIs
  • Custom API endpoints
  • CRUD operations
  • Authentication & authorization
  • Database integration
  • Third-party API integrations
  • Webhooks & event handling
  • Business logic and workflows
  • API validation and error handling
  • API documentation
  • Existing Node.js fixes and improvements
  • Backend optimization and debugging

I can work with an existing codebase or build the backend from scratch.

My focus is on creating structured, maintainable backend systems that communicate reliably with your frontend, mobile application, database, or external services.
