yourkarma6788/MERN-PeopleSearchSite ? reverse-engineered prompt

Build me a simple people search website where I can look up records by things like RUT, name, and other keywords, then see matching results quickly on the page.

I also need a way to upload a large batch of people data into the database, so I can add or replace many records at once without doing them one by one. Make it feel like a straightforward admin style app, easy to use, clean, and fast.

Please set it up as a full working app with a backend and a client, and connect everything so the search and upload features actually work. If you need to check current docs or best practices while building it, go ahead and look them up online. Keep the UI simple and practical, with a search form, results list, and an upload section.
