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.
