sruthyarun/CRM-MERN ? reverse-engineered prompt

Build me a simple CRM web app for small teams, where I can keep track of customers, notes, follow ups, and basic contact details in one place.

I want a clean dashboard to see all customers, add a new contact, edit and delete records, search and filter the list, and open a customer profile to see their history and any notes or reminders. It should feel easy to use and look polished enough for a real business app.

Please set it up as a full stack app with a separate client and server, and make sure the frontend talks to the backend properly. Use sensible defaults, handle loading and error states, and make the forms straightforward for non technical users. If anything about the structure is unclear, look up current docs online if you need to and make the best practical choices.
