About this gig

Site throwing errors, build failing, or something broken in production? Send me the repo and the error message and I'll find the cause and fix it, usually the same day.


I work with React, Next.js, Node.js, Express, MongoDB, Flutter and Firebase.


Common issues I fix:

- Build and deployment errors (Vercel, Netlify, Render)

- API routes returning 404 or 500

- CORS and failed network requests

- MongoDB and Mongoose connection problems

- Broken login, JWT and Firebase authentication

- State and re-render bugs in React

- Layout breaking on mobile

- Firestore rules and permission errors

- Flutter build failures and dependency conflicts


What you get:

- The bug fixed and verified working

- A plain explanation of what caused it

- Clean code, no messy patches

- Fast replies while I work


Not sure how big the problem is? Message me the error and I'll tell you honestly which package you need.
