About this gig

App crashing, API not responding, or a page that just won't work? I'll find the cause and fix it.


I work with React, Next.js, Node.js, Express and MongoDB, and I've built and deployed several full-stack apps, so I know where things usually break.


What I fix:

- Console and build errors

- API and database connection problems

- Login and authentication bugs

- Broken forms, state and rendering issues

- "Works locally but not live" errors


What you get:

- A working fix, tested on your project

- A short note explaining what was wrong and how I fixed it, so it doesn't happen again


How it works:

1. Message me the error message or a short description of the problem

2. Share your code (repository or zip file)

3. I fix it and send it back


Note: this gig covers fixing existing bugs, not building new features. Large changes can be quoted as a custom offer.


Message me before ordering and I'll tell you if I can help.
