Digital Rolodex - Premium Business Cards

🚀 Inspiration

In our increasingly digital world, traditional business cards are becoming obsolete, while platforms like Linktree offer basic functionality but lack the professional polish and comprehensive features professionals need. We envisioned a solution that combines the elegance of premium business cards with the convenience of digital sharing and the security of client-side encryption.

🎯 What it does

Digital Rolodex transforms how professionals share their contact information and showcase their work. It creates beautiful, interactive digital business cards that can be easily shared via QR codes. Users can:

Create Multiple Cards: Build a complete rolodex of professional contacts
Showcase Portfolios: Include project highlights with images, descriptions, and links
Share Instantly: Generate QR codes for immediate sharing at networking events
Maintain Privacy: All data is encrypted client-side - no servers, no data collection
Professional Design: Apple-level aesthetics with smooth animations and responsive design

⚡ How we built it

Frontend: React + TypeScript + Tailwind CSS

Modular component architecture for maintainability
Responsive design that works flawlessly on all devices
Lucide React icons for consistent, professional iconography
