About this project

Emergency Blood Donor Finder System (PulseLink) is a web-based mini project developed using Python Flask and SQLite. The application connects voluntary blood donors with people searching for blood donors. Users can register, log in, manage their profiles, search for available donors by blood group and city, create emergency blood requests, and respond to requests. The system includes a responsive landing page, personalized dashboard, donor directory, blood request management, and secure password authentication. It is suitable for VTU 5th Semester CSE and ISE students to learn full-stack web development, database management, and authentication. This is an educational demonstration project and not a verified medical emergency service.
