I will fix react errors hooks state npm install and next js routing issues

Please share your code repository (GitHub/GitLab link or ZIP file), the error message or console log, and a brief description of what's not working. A screen recording of the issue is also very helpful.

For small, isolated bugs, sometimes yes — but for most issues, I'll need access to the relevant code to properly diagnose the root cause rather than guessing.

Yes. I handle React.js and Next.js frontend bugs as well as Node.js/Express backend and API issues, including database connection problems.

A bug fix addresses specific broken features or errors in your existing code. A rebuild means restructuring, refactoring, or migrating your codebase (e.g., converting JavaScript to TypeScript, or upgrading React to Next.js) for better performance and maintainability.

Yes, I provide a summary of the issues found, what was fixed, and any recommendations for future improvements.

Yes, I'm happy to sign an NDA if required and treat all client code and data with full confidentiality.

I'll message you immediately to discuss the situation. Depending on the complexity, we can adjust the package or scope before continuing — no surprise charges.

Small feature additions can sometimes be included depending on scope — message me with details, and I'll let you know if it fits within the package or needs a custom quote.

Basic support for the delivered fix is included. For ongoing maintenance or future updates, we can discuss a separate arrangement.

React.js, Next.js, Node.js, Express, TypeScript, JavaScript, Tailwind CSS, and REST APIs. I also work with common databases like MongoDB, MySQL, and PostgreSQL.
