TIMELINE
About the Project
Architected a fullstack QR management system featuring multi-database abstraction (MongoDB & Supabase), server-side Sharp image compositing, and scan analytics with collision-safe unique codes.
Key Contributions
Dual-Database Adapter Pattern
Designed an interchangeable database abstraction layer supporting MongoDB (Mongoose) and Supabase (PostgreSQL) controlled via environment variable configuration.
Server-Side Matrix & Sharp Compositing
Engineered high-performance image processing pipelines using Sharp to apply custom dot/corner shapes, embedded brand logos, and multi-code A4/Letter print sheet layouts.
Collision-Safe Tracking Engine (QUC)
Built a 12-character unique tracking code generator with collision retries, automated scan logging (IP, User-Agent, timestamp), and instant redirect verification.
