You will get your Next.js or React app bugs fixed and performance improved


Project details
Is your Next.js or React app broken, slow, or behaving unexpectedly in production?
I'll dig into your codebase, find the root cause, and fix it properly — not with a patch that breaks something else next week.
What I fix:
— Runtime errors and broken functionality
— Slow page load and poor Core Web Vitals
— API errors and broken integrations
— Authentication and session issues
— Responsive design and layout bugs
— Deployment and build failures on Vercel or Cloudflare
I work with Next.js, React, Supabase, Prisma, and Node.js daily in production. I understand how these systems break and exactly where to look.
Share your issue before ordering — I'll confirm I can fix it and which tier applies.
