FAQ
What do you need to start the fix?
To begin immediately, I need three things: 1) A brief description of the issue. 2) A screenshot or text of the error log from your console/terminal. 3) Access to your repository (GitHub invite or a ZIP file of the source code).
Can you fix Next.js hydration or build errors?
Yes. These are common issues in Next.js 14 and 15. I specialize in resolving hydration mismatches, server-side rendering (SSR) conflicts, and Vercel deployment failures by ensuring your components and data-fetching logic are correctly structured.
Do you work with TypeScript and modern State Management?
Absolutely. I prefer working with TypeScript to ensure type safety. I can debug issues within Redux Toolkit, Zustand, Context API, and TanStack Query (React Query) to ensure your application state is predictable and bug-free.
What if the bug is larger than the "Basic" package?
If the issue requires a deep architectural overhaul or involves multiple complex files, I will provide a detailed diagnostic report and a custom offer. Transparency is key—I will always explain the "why" behind the fix.
Is my code secure with you?
Yes. As an Open Source contributor, I follow strict security protocols. I will never share your code, and I ensure that environment variables and sensitive API keys are handled securely during the debugging process.
