About this gig

Site broken? Error you can't figure out? I'll find the root cause and fix it properly very fast.


I'm a Next.js and React developer who builds and runs live production websites, so I debug with a builder's understanding I don't patch symptoms, I fix causes and tell you what went wrong.


I fix:

  • -

Hydration errors, build failed, and Vercel deployment errors

-

Blank white screen, page not loading, console errors

-

API not working, fetch/data issues, broken forms

-

Broken mobile layout and responsive design issues

-

Slow websites, npm install errors, dependency conflicts

-

React state bugs, routing problems, component crashes


How it works:

1. Message me a description of the problem (screenshots or error text help)

2. I confirm the fix scope, price, and time honestly

3. I fix it, test on desktop + mobile, and explain what caused it so it doesn't come back


What you always get: the root cause fixed (not hidden), clean code, a plain-English explanation, and zero risk to the rest of your site.


I never need your passwords GitHub collaborator access or a ZIP of your code is all it takes.


Contact me before ordering so I can look at your specific bug.
