About this gig

Is your build failing on Vercel right before launch? Or did your Supabase authentication just break after updating your Next.js route middleware?


I am a full-stack developer who works daily with the Nextjs, React, Node, and Supabase stack. Instead of wasting hours scrolling through old GitHub issues, let me jump in and fix the root cause today.


What I can fix right now:

  • Vercel & Nextjs: Vercel 404 Error, Failing builds, strict TypeScript/ESLint errors, missing environment variables, hydration mismatches, and broken App Router pages.
  • Supabase Crises: Broken OAuth/Magic Links, misconfigured Row-Level Security (RLS) policies blocking your data, session persistence drops, and real-time subscription errors.
  • Node & React: CORS blocks on API routes, infinite useEffect loops, and broken third-party webhooks (Stripe, etc.).


Why work with me?

I don't just paste a quick hack. I find the structural issue, patch it properly, and make sure your app actually deploys live.


PLEASE MESSAGE ME BEFORE ORDERING!

Click "Contact Seller" and paste your Vercel build logs or console errors first. I need to review the code to guarantee a fix and set a fair timeline.
