Gig Summary
About this gig
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.
