A visitor analytics system deployed on Vercel tracks page interactions across this GitHub profile in real time.

This profile includes a comprehensive visitor analytics system that tracks how people interact with this GitHub presence. It provides insights into:

• 👁️ Page Views — Profile visit count, referrer sources, device types, geographic data
• 🖱️ Click Tracking — Every link and button clicked, with coordinates and scroll depth
• 📜 Behavior Patterns — Time on page, scroll depth, session duration, interaction count
• 📱 Device Distribution — Desktop vs. mobile vs. tablet breakdown
• 🔗 Top Content — Most-clicked links and most-engaged projects

The analytics infrastructure includes:

Visit Profile
  └─► Tracking script loads
        └─► Records: page view, device, referrer, timestamp
              └─► Events sent to analytics backend
                    └─► Stored in analytics-data/{projectId}/{date}/*.jsonl
                          └─► Dashboard generated from aggregated data
                                └─► Markdown report & HTML dashboard available

The system collects only non-personal analytics data:

• Session ID (anonymous token, not connected to identity)
• Device type & screen resolution
• Browser & OS information
• Referrer source
• Links clicked and interaction coordinates
• Scroll depth and time on page
• Page visit timestamps

✅ No personal data collected (no names, emails, or IP addresses logged) ✅ Fully anonymized sessions — Session IDs are random, not linked to identity ✅ Optional tracking — Can be disabled via configuration ✅ Local storage first — Events stored locally before sending ✅ User data control — Data can be cleared from browser localStorage

For local testing:

# Start the analytics server
node scripts/analytics-server.js
# Server runs on http://localhost:3001

# Generate dashboard
node scripts/dashboard-generator.js
# Output: analytics-dashboards/index.html & ANALYTICS_REPORT.md

# Collect metrics
npm run collect-metrics
# Output: metrics/analytics.json with 90-day history

A RAG-powered chatbot that lets users ask natural-language questions against documentation — with source citations, confidence scoring, and automatic content gap detection.

A complete RAG pipeline: crawl documentation sites, split content using section-aware chunking (respects heading hierarchy, never splits code blocks), embed with OpenAI text-embedding-3-small, store in ChromaDB, and answer questions with GPT-4o-mini citing exact sources. The Next.js chat frontend features message bubbles, source citation cards, confidence badges (green/amber/red), collection selector, and dark/light mode. Low-confidence answers are automatically logged as content gaps.

Doc sites → Crawl → Section-aware chunking → Embed (OpenAI)
