Let'sDonate | Full-Stack Blood Management System

Let'sDonate is a robust blood bank management platform designed to bridge the gap between donors and those in need. This project represents a significant evolution from local development to a professional, cloud-native distributed architecture.

Note on Implementation: While the frontend UI utilized a professional template, the primary technical focus of this development was architecting the Backend API, Cloud Database Integration, SSL Security, and End-to-End Deployment.

🚀 Technical Focus & Contributions

In this iteration, the project transitioned from a standalone application to a distributed system:

• Cloud Database Migration: Successfully migrated data from local MySQL (XAMPP) to TiDB Cloud (Serverless) for global accessibility and scalability.
• Secure Infrastructure: Implemented SSL/TLS encryption for all Node.js-to-Database communication to prevent insecure data transport.
• Decoupled Deployment: Orchestrated a multi-platform deployment pipeline using Render (API) and Vercel (Frontend).
• Environment Security: Managed sensitive credentials via environment variables and robust .gitignore configurations.

📂 System Architecture

The application follows a standard three-tier architecture:

1. Client-Side (Vercel): React application communicating via Axios.
2. Server-Side (Render): Node.js API processing business logic and database queries.
3. Data Layer (TiDB Cloud): Distributed MySQL-compatible database.
