Voisek

Phone-fraud protection that banks build into their own apps: fraud calls blocked before they ring, smishing filtered out of SMS.

Context

VoiSek, based in Miami, sells anti-vishing, anti-smishing and branded caller ID to banks, healthcare providers and telecoms. Its VoiShield API runs inside the client's own iPhone and Android app, so the people it protects have nothing extra to install.

What I owned

Developed and optimised the native mobile SDK behind the voice-security engine.
Anti-smishing and anti-vishing detection, caller reputation scoring and allow/block list logic.
Background services that detect incoming calls and read SMS, with the user's permission, to trigger real-time fraud checks.
System-level permissions, localisation and device integration, so protection stayed accurate without getting in the way.
