The goal was to create a seamless, automated digital solution that ensured high data integrity without compromising user experience.
I architected a robust Flutter application integrated with a Google Cloud Platform (GCP) & Firebase backend. The system replaces manual sign-ins with a secure, event-specific 6-digit code validation system.
• Eliminated proxy attendance and ensured user privacy by developing a Flutter application that executes Geofencing verification locally on the client-side, ensuring zero raw location data is transmitted to the server.
• Optimized user experience, achieving 35% faster check-in times by implementing A/B testing via Firebase Remote Config to dynamically toggle Geolocator settings based on real-time network conditions.
• Reduced false-negative validation errors by 12% by conducting rigorous Hypothesis Testing to calibrate the geofence radius, balancing security requirements with GPS hardware limitations.
• Neutralized GPS spoofing attacks by engineering Automated ETL Pipelines that feed into an Outlier Detection model, identifying spatial anomalies in "successful" check-ins that bypassed initial validation.
• Enabled scalable, zero-downtime event management by architecting a hybrid data model using GCP Firestore for real-time syncing and Cloud SQL (Firebase)for structured historical archiving.
• Streamlined institutional onboarding by integrating Federated Authentication with University SAML SSO, reducing login friction while maintaining strict access control standards.
