On-device recognition
CameraX handles capture and ML Kit reads text locally. A review step lets users correct extracted fields before saving a contact, rather than treating OCR output as final.

My contribution
Android Developer
Built the scan-to-contact workflow, from camera capture and gallery import to editable OCR results, searchable contact profiles, reminder scheduling, and CSV export. Developed the Kotlin and Jetpack Compose application and published it on Google Play.

Room / Flow / WorkManager
Engineering approach
Local data, reactive screens
Room persists contacts and follow-ups. Coroutines and Flow feed ViewModel state into Compose screens, with explicit user actions and Koin dependency injection.
From a scan to a follow-up
WorkManager schedules reminder notifications, while contact status and completion tracking support the next conversation. CSV export lets users take their contact data with them.
