AlzCare (Gedo)
A dedicated healthcare platform connecting Alzheimer’s patients and family caregivers through scheduled medication alerts, health records, and shared memory notes.
Simultaneous push alert delivery across paired patient and caregiver devices
Zero orphaned files on cloud storage during updates and deletions
NoSQL injection sanitization, HTTP parameter pollution protection & rate limiting
01: Operational Challenge & Concurrency Bottleneck
I designed and built the backend API, the scheduling engine, and the media processing pipeline.
Caring for Alzheimer’s patients often leads to missed medication times, unmonitored dietary habits, and communication gaps between patients and family members, causing preventable health risks.
Delivering reliable dual-recipient reminder notifications across complex recurring weekly schedules without timing drift, while managing voice and image assets without storage leakage.
I built a background scheduler synchronized with localized time slots that fans out push notifications to paired devices via Firebase Cloud Messaging, backed by a Cloudinary media pipeline that prunes stale assets upon record updates.
