You will get professional Next.js React bug fixes and improvements
Project details
I will professionally diagnose and fix bugs in your existing Next.js or React application. I can resolve authentication issues, Supabase and database errors, API problems, broken UI, responsive design issues, TypeScript errors, performance problems, and unexpected application behavior.
I work carefully within your existing codebase to identify the root cause and implement a clean, maintainable fix without unnecessary changes.
I can help with:
• Next.js and React bugs
• TypeScript errors
• Supabase authentication and database issues
• Login, signup and password reset problems
• API and server errors
• Responsive UI and layout issues
• Performance optimization
• Build and deployment errors
• Existing code improvements
Before starting, I will review the issue and provided information to confirm the scope. Complex issues or multiple unrelated bugs may require the Standard or Advanced package.
My goal is simple: find the problem, fix it correctly, test the solution, and deliver clean working code.
