Acerca de este Servicio

With 10+ years of experience, I build fast, secure, and scalable Node.js applications using Express and MongoDB, from a single REST endpoint to a full production backend. I also work comfortably with AI-assisted code from Claude, Cursor, Replit and similar tools, so if part of your app was AI-generated, I can clean it up, connect it to a real database, and deploy it properly.


What I Offer

  • Custom REST API Development (Node.js + Express)
  • Database Design & Integration (MongoDB, MySQL)
  • Authentication & Authorization (JWT, OAuth)
  • AI Feature Integration (OpenAI, Claude, Gemini APIs) for chatbots, smart search or automation
  • Fixing & Extending AI-Generated Code (Claude, Cursor, Replit)
  • Bug Fixes & Performance Optimization
  • Third Party API Integrations
  • Clean, Documented, Production Ready Code
  • Mobile App Development (React Native, Flutter) on Request

What You Get

  • Direct Communication & Fast Response
  • Well Structured, Scalable Code
  • 1 Month FREE Post Launch Support
  • Fast, Reliable, & Scalable Solutions

Message me before ordering if you have a custom requirement, and let's build something reliable together.

    Great experience working with the seller again. This is my second time working with them, and they were once again professional, responsive, and understood the requirements well. The work was completed as expected, and they were willing to make adjustments when needed. Overall, reliable seller and I would be happy to work with them again.
