Taply

Overview

Taply is a live, production-grade digital business card app built for developers, students, and professionals. Update your profile once, and every QR code you've ever shared updates instantly — no app install required from the recipient.

Problem Statement

Traditional contact cards go stale the moment they're printed. Taply replaces the paper card ritual with a dynamic profile tied to an auto-updating QR code. Anyone with a standard camera can scan it; no app install required.

Architecture

Taply uses a React Native + Expo frontend with Supabase as a complete backend-as-a-service — handling authentication, PostgreSQL storage, file uploads, and Row Level Security so users can only modify their own profile while keeping public read access for QR scans.
