DevCard

One Tap. Every Profile. Every Platform.

Open Source Developer Profile Exchange Platform

Features • Quick Start • Architecture • Contributing • License

At every developer meetup, hackathon, or conference, the same friction plays out:

"What's your LinkedIn?" → open LinkedIn, search, send request
"Do you have GitHub?" → open GitHub, search, follow
"Are you on Twitter?" → open Twitter, search, follow

Each exchange is manual, error-prone, and slow. DevCard fixes this.

DevCard aggregates all your developer profiles into a single shareable QR code. The receiver opens one screen and can follow/connect on every platform — without switching apps.

• 🔗 Universal Profile Aggregation — GitHub, LinkedIn, Twitter/X, GitLab, Devfolio, and 10+ more platforms
• 📱 QR Code Sharing — Show your QR, they scan, done
• ⚡ One-Screen Multi-Platform Connect — Follow on GitHub, Connect on LinkedIn, all from one card
• 📈 Advanced Analytics — Track who viewed your card, when, and from where (Web, QR, App)
• 🔌 Per-Platform OAuth Integrations — Securely connect accounts for "Silent Follows"
• 🎯 Context Cards — Different cards for different situations (Professional, Hackathon, Community)
• 🌐 Web Backup — Receivers don't need the app — works in any browser
• 🔒 Privacy-First — No tracking, no data selling, your data stays yours
• 🛠️ Open Source — Apache 2.0 licensed, community-governed

• Node.js >= 20
• pnpm >= 9
• Docker & Docker Compose
• React Native development environment (setup guide)
