    ├── learning_path.html ✅ (NEW)
    ├── ai_chatbot.html ✅ (NEW)
    └── (all other existing templates)

3. Environment Setup ✅

Optional but Recommended:

# Set cache directory
export TRANSFORMERS_CACHE=/tmp/hf_cache
mkdir -p /tmp/hf_cache

# Set Flask secret
export FLASK_SECRET_KEY=your-secret-key-here

4. First Run ✅

python app.py

What Happens on First Run:

1. Creates /tmp/database.db
2. Initializes database schema
3. Inserts test data (users, resumes, internships)
4. Downloads ML models (~750MB) to /tmp/hf_cache
5. Starts Flask server on port 7860

Expected Console Output:

[INFO] Database schema initialized
[INFO] Inserted comprehensive test data
[INFO] Advanced ML features loaded successfully
[INFO] Semantic model loaded successfully
[INFO] Sentiment analyzer loaded successfully
[INFO] NER model loaded successfully
 * Running on http://0.0.0.0:7860

⏱️ Time: 3-5 minutes (first time only, due to model downloads)

---

Testing Checklist

✅ Basic Functionality

• Open http://localhost:7860
• Homepage loads
• Can navigate to login pages
• Login works with test credentials

✅ Test Users

Intern:

Email: alice.smith@example.com
Password: password

Recruiter:

Email: emma.wilson@techcorp.com
Password: password

Admin:

Email: admin@example.com
Password: password

✅ ML Features Test (As Intern)

• Dashboard shows ML-powered buttons (purple gradient)
• "🤖 AI Resume Scorer" opens and works
• "🎓 Learning Path" generates recommendations
• "💬 AI Career Chat" responds to questions
• "🎯 Predict Success" button appears on internships
• Click "🎯 Predict Success" shows probability
• "ATS Insights" shows both keyword and semantic scores
• "Mock Interview" provides detailed NLP analysis

✅ ML Models Loaded

Check logs:

tail -f /tmp/logs/app.log | grep ML

Should see:

[INFO] Advanced ML features loaded successfully
[INFO] Semantic model loaded successfully
[INFO] Sentiment analyzer loaded successfully
[INFO] NER model loaded successfully

✅ Performance Check

• Dashboard loads in < 2 seconds
• AI Resume Scorer returns results in < 3 seconds
• Success Predictor calculates in < 2 seconds
• Semantic matching updates immediately

Troubleshooting

Issue: "ModuleNotFoundError: No module named 'ml_utils'"

Solution:

# Ensure ml_utils.py is in SkillSync directory
ls -l ml_utils.py

# If missing, verify you're in correct directory
pwd  # Should end with /SkillSync

Issue: "ML features not available"

Debug:

python -c "from ml_utils import ML_FEATURES_ENABLED; print(ML_FEATURES_ENABLED)"

If False:

1. Check requirements installed: pip list | grep sentence
2. Check for import errors in logs
3. Verify internet connection for model downloads

Issue: Models downloading slowly

Solution:

• Be patient (750MB download)
• Check internet connection
• Models are cached after first download

Issue: Out of memory

Solution:

• Ensure 2GB+ free RAM
• Close other applications
• Restart application

Issue: Port 7860 already in use

Solution:

# Kill existing process
lsof -ti:7860 | xargs kill -9

# Or change port in app.py
# app.run(port=5000)

Production Deployment Checklist

✅ Security

• Change default admin secret code
• Set strong Flask secret key
• Use environment variables for secrets
• Enable HTTPS in production
• Implement rate limiting

✅ Performance

• Use production WSGI server (Gunicorn)
• Enable caching for embeddings
• Consider GPU for faster inference
• Set up load balancing if needed

✅ Monitoring

• Set up logging infrastructure
• Monitor model performance
• Track API response times
• Set up error alerting

✅ Database

• Migrate from SQLite to PostgreSQL for production
• Set up backups
• Implement connection pooling
