About this gig

Need a modern, scalable, and high-performing web application? You're in the right place.

I develop custom backend services, REST APIs, real-time applications, and full-stack solutions using JavaScript, TypeScript, and Node.js. Whether you're launching a startup, expanding an existing platform, or fixing issues in your current project, I deliver clean, maintainable, and production-ready code.

What I can help you with:

  • Custom Node.js application development
  • JavaScript and TypeScript development
  • RESTful API development and integration
  • Express.js backend development
  • Authentication (JWT, OAuth)
  • Database integration (MongoDB, PostgreSQL, MySQL)
  • Third-party API integration (Stripe, PayPal, OpenAI, Twilio, Firebase, and more)
  • Real-time applications using WebSockets or Socket.IO
  • Bug fixing, debugging, and performance optimisation
  • Code refactoring and feature enhancements
  • Deployment to cloud


Whether you need a simple API, a complete backend system, or assistance with an existing application, I'm committed to delivering a solution that meets your requirements and is ready for production.
