LeedECard — Digital Card with Lead Capture & AI

Overview

LeedECard is a SaaS digital business card I built from scratch. The pitch: your entire business in one link. It shares by QR code, captures every lead who scans it, and drafts your follow-ups with AI, so a single scan turns into a booked client with no app to install. It is built for solo pros like hair stylists, personal trainers, real estate agents, photographers, and consultants, and ships with a free tier plus a $5/month Pro plan.

Key Features & Technologies

The platform was built with a modern, full-stack architecture:
Next.js 14 (App Router) for the frontend and server-side rendering
Supabase for database, authentication, and real-time data
Stripe for subscription billing and payment management
TypeScript throughout for type safety
Tailwind CSS for responsive, utility-first styling
QR code generation and sharing functionality
Booking link integrations (Calendly, etc.)
Analytics dashboard for card view tracking
Automatic lead capture: every scan or card view is saved as a lead, with lead scoring to surface the warmest prospects
AI-drafted follow-up emails so a scan turns into a booked client, sent from your own inbox
Free-forever plan for the card, QR, and booking links; Pro at $5/month adds lead capture, scoring, AI follow-ups, and analytics, with a 14-day trial

Results & Impact

LeedECard launched as a complete SaaS product with a freemium model. The platform demonstrates end-to-end product development skills including authentication flows, payment processing, subscription management, and user-facing dashboards. The project showcases ability to build and ship a complete product independently.
