I will fix react js bugs and javascript errors and vercel deployment issues


About this gig
Your build passes locally and fails on Vercel. Or it deploys and the page is blank. Or it worked yesterday and nobody changed anything.
I fix that. Node js and React js build errors, deployment failures, broken environment variables, hydration errors, module resolution, memory limits, and the deploy itself once it works.
WHAT I FIX
- Build fails on Vercel, Netlify
- Blank page or 500 error after a successful deploy
- Hydration and server client mismatch errors
- Environment variables not loading in production
- Module not found and dependency version conflicts
- Out of memory and build timeout failures
- Custom domain, DNS, SSL and redirect problems
- Node version and package manager mismatches
WHERE I DEPLOY
- Vercel
CI/CD pipelines, Docker, Nginx, PM2, staging environments and monitoring.
I have deployed over 20 projects on Deployment errors are the thing I see most, so I usually recognise yours from the log.
Send me the build log or a screenshot of the error plus repo access. I will tell you what is wrong and which package covers it before you order.
