FAQ
Will you explain what caused the issue?
Absolutely. Every fix includes a brief explanation of the root cause and what to avoid in the future. Transparency builds reliability.
What do you need from me to start?
Please provide a read-only GitHub repository (or a ZIP), clear steps to reproduce the issue, screenshots or console logs, your Node and Next.js versions, and how you usually run the project (npm run dev or npm run build).
Can you fix build or deployment issues (Vercel, Docker, etc.)?
Yes. I can debug build failures, environment variable issues, and deployment errors on Vercel, Docker, or any other host. I’ll verify the fix with a clean build before delivery.
