FAQ
1. What information do I need to provide?
To start immediately, I need a brief description of the bug, the URL of your website, and screenshots of the error (especially from the Browser Console). Additionally, I will require access to your source code via GitHub, GitLab, or your hosting credentials.
2. Do you fix React and Next.js build or deployment issues?
Yes, I can help with build errors, hydration issues, runtime bugs, rendering problems, and deployment-related issues in React or Next.js apps.
3. Is my source code and data secure with you?
Absolutely. With my background in web security and projects like NodeShield, I follow strict protocols to keep your code confidential. My research in SBOM/CBOM also ensures your dependencies are handled with professional care.
4. Do you work with modern frameworks like React and Next.js?
Definitely. I am highly proficient in React and Next.js (including SSR and SSG issues). I can also assist with legacy codebases that still use jQuery or plain JavaScript.
5. What if you are unable to fix the bug?
I offer a "No Fix, No Pay" guarantee—if I can't solve it, you get a full refund. However, with my experience building complex systems like moet-system-admin, I am confident in resolving almost any technical hurdle.
