FAQ
Do you work with both the new Next.js App Router and the older Pages Router?
I am fully experienced with the modern Next.js 13/14 App Router, Server Components, and the traditional Pages Router. I can fix bugs in either version.
What do you need from me to get started?
Ideally, you will invite me to your GitHub repository so I can test the code on my local machine. If that is not possible, I can work via TeamViewer or AnyDesk, or you can send a Zip file of the code.
Can you fix bugs on a live site (Vercel/Netlify)?
Absolutely. I am an expert in debugging deployment errors that happen on Vercel, Netlify, or standard hosting, even if the app works fine on your local computer.
What happens if you cannot fix my bug?
If I cannot solve your issue, I will cancel the order instantly and you will not be charged a single penny. It is 100% Risk-Free for you.
Do you also fix design issues (CSS / Tailwind)?
Yes. I am very strong in Tailwind CSS and standard CSS. I can fix alignment issues, mobile responsiveness, or layout glitches to match your design perfectly.
