Kotlin app with Google Auth and Firebase persistence. A small product with a complete loop.
KotlinAndroidFirebaseRFID
SLIP was built to make exchanging contact info feel physical again, without the business-card pile. RFID for the handshake, Firebase for the cloud, Google Auth so profiles were real people.
It is the independent project that proves I will finish a loop: client, auth, store, a reason to open the app.
