Delivery Application
AI-Powered Package Tracking for Apartments
A scalable apartment package management system using OCR, AI-assisted processing, and real-time tracking to automate package registration, delivery, and residential package handling workflows.
Project Overview
Managing apartment deliveries manually creates delays, data entry errors, and operational inefficiencies for residential staff and building management teams. We developed the Delivery Application, an AI-powered delivery management system that streamlines package registration, tracking, and distribution through automation and intelligent data extraction. The goal was to build more than a package tracker. It was to create a complete package management platform that improves operational efficiency, reduces human error, and modernizes residential delivery workflows.
