At VD system, I work on web and mobile applications for business use cases including attendance tracking, construction-site management, security patrols, and compliance monitoring.
I work on React Native check-in apps that use NFC for employee attendance and SignalR for real-time updates. I also contributed offline-mode handling with network detection and automatic reconnection.
For the Construction Site Check-In System, I worked on geolocation-based attendance and an admin dashboard for analytics, site management, and worker assignments.
I also worked on a security patrol tracking system using BLE beacons to monitor routes and checkpoints, and built web projects including a fire extinguisher compliance dashboard and the TIS Mitrovic Market website.
