The Problem
Access management was fragmented across locations, with no single source of truth and no reliable bridge between cloud records and the physical biometric devices at the gates.
The Solution
Led full-stack development of a centralized system in Python/Django, engineering a reliable sync layer between cloud architecture and ZKTeco biometric hardware, and optimizing the dop_verification database for fast, accurate verification at scale.
The Impact
A single secure, auditable system of record; reliable hardware-to-cloud syncing; and a query-optimized verification database that holds up under real-world load.
