A complete SaaS platform that transformed manual raffle ticket sales into an automated system with payments, live draws, and mass messaging.

Car Show Paraguay ran high-end car raffles using completely manual processes: Excel sheets, unverified bank transfers, chaotic WhatsApp groups, and draws that depended on everything going right on the day. With thousands of participants per raffle, the process was unsustainable.
We built a complete SaaS platform from scratch: raffle management, QR tickets, live payment gateway, admin panel, Android app for live draws, and a WhatsApp smart-queue system capable of handling 100K messages per day.
Raffle creation, unique QR tickets, real-time admin dashboard, and automated winner management.
Local payment gateway integration. Automatic verification, zero incidents, instant WhatsApp receipt to the buyer.
Mass messaging system with intelligent queue that respects API limits and delivers 100,000 personalized messages in 24 hours without blocks.
Native Kotlin app for running draws live in front of the audience. Transparent, auditable, with on-screen animations.
