Overview
I transformed digital raffle management in the Dominican Republic. AdrenalinaRD is not just a raffle site; it’s a robust infrastructure designed to withstand massive traffic spikes during live events, ensuring transparency and stability when it matters most.
The Technical Challenge
The client needed a solution capable of instant scaling. During live draws, traffic surged from 0 to 10,000 users in seconds.
Critical Points Solved
- Extreme Concurrency: Preventing server crashes during massive ticket sales.
- Data Integrity: Ensuring no duplicate tickets were sold within milliseconds.
- Transparency: Auditable and visible winner selection system.
My Solution
I designed and developed a performance-optimized full-stack architecture:
- Node.js & Express Backend: Implemented processing queues to handle transactions without blocking the main server.
- Optimized MySQL Database: Strategic indexing and ACID transactions to ensure financial integrity of every ticket sold.
- AWS S3: Efficient storage for promotional assets.
- Omnichannel Support: Responsive admin dashboard allowing real-time event management from mobile.
Business Impact
The platform allowed the client to automate 100% of their workflow:
- Automated Management: From raffle creation to winner selection and payment collection.
- User Experience: Ticket purchase in < 3 clicks and real-time tracking.
- Zero Downtime: Successfully supported multiple high-profile events without interruptions.
