CraftsmenLtd/BloodConnect ? reverse-engineered prompt

Build me a web app called BloodConnect for helping people find blood donors fast in emergencies.

It should let someone request a blood group, location, and urgency, then show the best matching donors nearby first. I want donors to be able to sign up, keep their profile updated, and automatically track when they last donated so people are only matched with someone who is actually eligible. The app should also help protect donor privacy, so the receiver only sees the information that’s needed, not private contact details unless the donor chooses to share them.

Please include a simple way for donors, blood banks, and donation organizations to manage requests and communicate with each other. It should feel clear and easy to use, with some basic reporting or stats for organizations too. If you need to check current docs or best practices while building it, go ahead and look them up online.
