ScamShield

Logic survived full rebrand

UX that outlasts a rebrand

Designed the core UX logic for ScamShield, including protection toggles, caller ID controls, spam filtering settings, and the full manage calls flow with allowed, blocked, and send-to-voicemail lists.

When T-Mobile migrated its entire platform into T-Life, this UX architecture came with it intact. It remains in use today serving over 10 million customers.
