About this gig

Backend Developer | Node.js, NestJS, API & AI Integration Expert

Hi there! I'm a senior backend developer who builds clean, scalable, and secure backend APIs using Node.js, NestJS, and modern databases. Whether you need a new API, refactor an existing API, add or improve features to ur project, or AI-powered automation, I've got you covered.


What I can help you with:

  • Building reliable backend APIs and microservices
  • Setting up authentication and authorization (including social logins)
  • Integrating payment gateways
  • Adding communication features like emails (SendGrid), SMS (Twilio), and push notifications
  • Creating AI-powered workflows using OpenAI, AI plugins, and custom automation
  • Designing and optimizing databases with SQL and NoSQL (MongoDB, DocumentDB)
  • Debugging, refactoring, and improving existing backend systems

I believe in clear communication, timely delivery, and writing code that you can trust and grow with. Lets chat before you order so we can make sure your project gets the best start.

    It was a pleasure to work with Hanif. He responded promptly and delivered the project quickly. The completed project functions well, and after the initial delivery, he quickly implemented the requested revision, adding the feature as needed. Highly recommended!
