I will deploy your nextjs app on vercel, fix build errors, setup domain and supabase
Khaleed K
About this gig
Launching your Next.js app shouldn't end with deployment errors.
If your vercel deployment keeps failing, your domain won't connect, or your Supabase backend isn't working properly. I will fix it and get your app production ready.
I specialize in production deployment and DevOps for modern JavaScript apps, handling everything from Vercel deployment to full Supabase backend setup. I understand how build pipelines, environment variables configuration, DNS records, and API connections work together in real world production environments.
You don't just need hosting, you need it working flawlessly.
WHAT I DO:
- Deploy Next JS app on Vercel
- Fix Vercel build error & production issues
- Supabase backend setup (auth, DB, RLS)
- Firebase hosting & Netlify deployment
- Domain DNS setup (A, CNAME, TXT, SSL)
- Connect domain to Vercel
- Environment variables configuration
- API & CORS error fixes
You get a stable production deployment, secure backend connection, and fully working live app. I troubleshoot the root cause, optimize the build pipeline, and ensure everything works in real production.
Message me with your repo and current issue before ordering so I can guide you properly.

FAQ
What if my build keeps failing on Vercel?
If your Vercel deployment keeps breaking, I will diagnose and fix the root cause. whether it’s dependency conflicts, incorrect environment variables configuration, API errors, or misconfigured build settings. I don’t just patch errors, I fix the build pipeline so your production deployment runs well
Can you fix deployment errors even if another developer worked on it?
Yes. Most of my clients come to me after failed attempts. I specialize in fixing complex deployment issues, including fix build error cases on Vercel, Firebase hosting, and Netlify deployment. I review logs, configs, and integrations to stabilize your app properly.
What access do you need to get started?
Typically: GitHub/GitLab repo access Hosting access (Vercel, Firebase hosting, Netlify) Domain provider (for domain DNS configuration) Supabase project access (if backend involved) If you’re unsure, message me first and I’ll guide you securely.
Can you connect my domain and configure DNS properly?
Yes. I handle complete domain DNS configuration including A records, CNAME, TXT, and SSL setup. I will connect domain to Vercel or any hosting platform and ensure it’s correctly pointing to your production deployment.
My Supabase authentication is not working. Can you fix it?
Absolutely. I provide full Supabase setup including auth configuration, database connection, RLS policies, redirect URLs, and API integration with Next.js. If login, signup, OAuth, or session handling is failing. I’ll resolve it.
Can you fix environment variable issues?
Yes. Many Vercel deployment failures happen due to incorrect environment variables configuration. I properly set server/client variables, secure keys, and production values to prevent runtime crashes and API connection errors.
Do you provide support after delivery?
Yes. I provide post deployment support to ensure your app stays stable after going live. If something related to the delivered production deployment breaks, I assist you. My goal is long term reliability, not just task completion.
Can you handle urgent or same day deployment?
If your launch is time sensitive, message me first. I often handle urgent vercel deployment fixes, domain issues, or supabase setup problems quickly depending on availability and complexity.
Can you deploy on Firebase Hosting or Netlify instead of Vercel?
Yes. I support Firebase hosting, Netlify deployment, and other modern platforms. I’ll configure builds, fix errors, and optimize the production deployment for performance and stability.
I’m not technical. Can you guide me?
Definitely. I work with founders and SaaS owners who aren’t technical. I explain what’s happening in simple terms and handle the technical side from fix build error issues to full backend and deployment setup.
