EY Raffle – Online Lottery & Ticketing System

The EY Raffle project was developed to digitize and streamline a traditional fundraising lottery event. The client required a modern, mobile-responsive web application that could handle tiered ticket pricing, discount bundles, and live prize assignment — all within a clean and accessible user interface.

We delivered a single-page application (SPA) that allows users to browse available prize categories, select their desired ticket packages, and instantly see their entitled tickets update in real time. The system dynamically calculates totals, applies package discounts, and manages complex inventory rules behind the scenes. Every user action — from adding a Grand Prize ticket to selecting a specific prize like a gift card or cash award — is reflected immediately in the summary panel without page reloads.

To ensure trust and transparency, the platform clearly displays the number of tickets the user is entitled to, the prizes they’ve selected, and the running subtotal. At the final stage, users complete their purchase through a secure payment gateway. The site also supports promotional free gifts for high-value purchases, encouraging larger contributions.

This project demonstrates our ability to build logic-heavy e-commerce functionality with a focus on clarity, speed, and reliability under real-world event conditions.
