Challenge

The university needed a robust solution to manage multiple QR code campaigns across campus events, facilities, and services. The existing third-party solutions were expensive, lacked customization options, and didn't provide detailed analytics. Additionally, there was a critical need to distinguish genuine user engagement from bot traffic and ensure the platform could scale to handle peak usage during major campus events.

Solution

Architected a custom platform using FastAPI for high-performance async processing and PostgreSQL for reliable data persistence. Implemented device fingerprinting and behavioral analysis to achieve 85% accuracy in bot detection. Built a comprehensive analytics engine that tracks scan patterns, user demographics, and campaign performance in real-time. Deployed on containerized infrastructure with Docker, enabling easy scaling and maintenance.

Impact

Processed 2,837 total scans across 92 unique campaigns serving 1,736+ unique visitors over 6 months. Achieved 85% genuine engagement rate through advanced bot detection, ensuring data accuracy for decision-making. Successfully supported 84% mobile and tablet users with optimized responsive design. Platform maintained 99.9% uptime during peak usage periods.
