A digital business card and smart contact book built around privacy. The core idea is gated reveal with reciprocal exchange: you control what strangers see, and private layers unlock only when both people share their contacts. Multiple cards per person (work, personal, project), QR and NFC sharing, a web vCard page for people without the app, caller ID and view analytics. Built on .NET 10 and PostgreSQL, with a React web app and an Expo mobile app; interface in Tajik, Russian and English.
