Overview:

The Flash Sales Platform is a dynamic e-commerce web application that enables sellers to host limited-time, high-discount sales on products. The key appeal is urgency — customers get heavy discounts for a short duration, encouraging quick purchases.

This platform is ideal for time-sensitive promotions, seasonal deals, or clearing old stock with excitement and buzz, similar to Amazon Lightning Deals or Flipkart Flash Sales.

Technologies Used:

• Frontend: HTML, CSS, Bootstrap, JavaScript

• Backend: PHP / Java (Spring Boot) / Node.js (Express)

• Database: MySQL / MongoDB

• Optional: Redis (for session management and caching), WebSockets for real-time updates

User Roles:

1. Customer: Browse and purchase flash sale items

2. Seller: Create and manage flash sale campaigns

3. Admin: Manage users, monitor sale activity, and approve listings

Flash Sale Mechanics:

• Real-Time Countdown Timers: Visible on product cards and detail pages

• Automatic Start/End: Sale becomes visible and active automatically at the scheduled time

• Stock Locking: Once added to cart, a short hold on stock is applied to avoid overselling

• Concurrency Handling: Prevents race conditions (e.g., two users buying the last piece simultaneously)
