FAQ
Do I need to provide the full source code?
Yes. To effectively debug the issue, I will need access to your source code. You can either add me as a collaborator on GitHub/Bitbucket or send me a ZIP file of the project (excluding the node_modules folder to keep the file size small).
Can you fix bugs in Next.js or Vite projects?
Absolutely! Whether your project is built with Create React App (CRA), Vite, Next.js, or Gatsby, I can handle the debugging process. I am also comfortable with both TypeScript and JavaScript environments.
What if you can't fix the bug?
While I have a very high success rate, some bugs are deeply rooted in third-party library limitations or complex backend issues. If I am unable to resolve the issue, I offer a full refund or a discounted rate for the investigation time, depending on our initial agreement.
Do you offer help with styling bugs (CSS/Tailwind)?
Yes. I can resolve layout issues, responsiveness problems, and styling conflicts using CSS Modules, Tailwind CSS, Styled Components, or UI libraries like Material UI and Ant Design.
Can we have a quick call to explain the issue?
Yes, for complex bugs, we can use the Fiverr Zoom integration feature. This allows us to screen-share so I can see the error happening in real-time, which often speeds up the resolution process.
