QuickCard.me is a streamlined platform for creating customizable digital business cards that blend functionality with a modern aesthetic. Designed for professionals and businesses seeking a contactless and easily shareable identity, the platform allows users to generate digital cards with embedded QR codes, profile links, and direct contact buttons.
Built using Ruby on Rails for the backend and styled with TailwindCSS, the system offers a fast, responsive experience across all device types. I implemented full-stack features including real-time analytics, social media sharing, and card customization.
The entire interface is mobile-optimized and delivers a professional digital presence that reflects the user’s brand.
