Deploy and fix React + TypeScript site (vercel blank page issue)

I have a website saved in my Github.
The codebase is React with TypeScript (.tsx files) but it is not properly configured for deployment and currently shows a blank page on Vercel.

I need an experienced frontend developer to:

Identify the exact setup (React, Vite or custom)

Fix missing build configuration (package.json, scripts, entry point)

Make the site render correctly

Deploy it properly on Vercel

Ensure the custom domain works

This is an MVP website. No redesign needed, only deployment and fixing setup issues.

If the developer can explain the setup briefly after fixing, that’s a plus.

That’s it.
