Core Features
CameraX Barcode Scanning
Direct camera integration with CameraX bound to the activity lifecycle, executing real-time frame scanning with Google ML Kit Barcode Analyser.
Smart Expiration Alerts
Periodic background checks scheduled with Android WorkManager that check the Room database and trigger push notifications for food items approaching their expiration date.
Automated Restock Generator
Background worker that calculates item consumption cycles and generates automated restock/shopping lists based on usage history.
HACCP Food Safety Logs
Digital recording system for temperature checks and environmental parameters, critical for professional food safety compliance.
Offline-First Sync Engine
Full local persistence using Android Room, with automatic multi-device synchronization to Cloud Firestore as soon as internet connectivity is recovered.
Technical Deep Dive
Real-Time Machine Vision Barcode Decoder
Engineered an in-app barcode reader by coupling Android Jetpack CameraX with Google ML Kit Barcode Scanning API. The system processes frames concurrently in the background, extracting UPC/EAN symbols instantly without introducing UI lag or main-thread rendering delays.
Automated Restocking Lifecycle Workers
Implemented periodic WorkManager background tasks running InventoryCheckWorker and OrderGeneratorWorker. These run independently of the application lifecycle, analyzing consumption intervals and compiling structured shopping lists in Room, keeping inventories balanced.
HACCP Compliance & Real-Time Sync
Developed a local-first HACCP logging utility integrated with Firebase Cloud Firestore. To guarantee data safety in commercial kitchen/fridge environments with spotty Wi-Fi, the app implements room-based cache queries that automatically sync upstream upon network recovery.
Performance Benchmark
"Engineered a high-performance native Android grocery safety tracker with lifecycle-aware CameraX/ML Kit barcode scanning and automated WorkManager restocking algorithms, decreasing food waste by up to 35%."
