About this gig

Something broken? Need a feature added fast?


I fix bugs and add features to existing Next.js, React, and MERN stack apps. No need to explain your entire codebase just tell me what's wrong or what you need, share your repo, and I'll get it done.


What I can fix


  • Auth issues JWT, sessions, login/logout bugs
  • API errors broken endpoints, CORS, data not saving
  • UI bugs layout broken, component not rendering, state issues
  • Database problems MongoDB queries, schema issues
  • Deployment failures Vercel, Render, env variable issues
  • Performance slow pages, unnecessary re-renders


What I can add


  • A new page or screen
  • A REST API endpoint
  • A form with validation and backend connection
  • Role-based access or auth guard
  • A small dashboard or data table
  • AI / LLM integration (ChatGPT, Gemini)


How it works


1. Message me with your issue and share your repo

2. I confirm scope and timeline before you order

3. I fix it, test it, and deliver clean code


I don't guess if I'm not sure I can fix it, I'll tell you before you pay.


Message me first so we can confirm your issue fits the package.

I'm a full stack product engineer with 1.5+ years of hands-on experience building real-world web applications using Next.js, the MERN stack, and AI integrations. Over the past year and a half I've gone from learning the fundamentals to shipping complete, production-ready products — a real-time chat platform deployed on Vercel and Render, and a B2B marketplace with AI-powered inventory management using Google Gemini 2.5. I don't just complete tasks I think about the product. Architecture, UX, performance, and clean code all matter to me. Available full-time. Fluent in English
