- 500 tasks per project: ~180ms to list, ~240ms to reorder
- Connection pool: 5-20 connections (configurable)
- Indexes on all filter/sort columns

---

## Security Considerations

### Frontend Security
- ✅ HTTPS enforced
- ✅ No secrets in code
- ✅ No sensitive data in localStorage
- ✅ Input validation on all forms
- ✅ XSS protection via DOM APIs

### Backend Security
- ✅ HTTPS enforced
- ✅ CORS properly configured
- ✅ Input validation with Zod
- ✅ SQL injection prevented (parameterized queries)
- ✅ Error messages don't leak internals
- ✅ No hardcoded credentials

### Deployment Security
- ✅ Environment variables for secrets
- ✅ Database user with limited permissions
- ✅ Process runs as non-root user
- ✅ File permissions restricted
- ✅ SSL certificates from Let's Encrypt

### Future (Phase 2)
- JWT authentication
- Role-based access control (RBAC)
- Audit trail logging
- Rate limiting

## Monitoring & Operations

### Health Checks

```bash
# Backend health
curl https://api.tekdek.dev/health
# Expected: {"status":"ok","db":"connected"}

# Frontend health  
curl https://command-center.tekdek.dev
# Expected: 200 OK with HTML
```

### Logging

```bash
# View real-time logs
tail -f /var/log/tekdek-command-center/api.log

# Parse JSON logs
tail -f /var/log/tekdek-command-center/api.log | jq .

# View PM2 logs
pm2 logs tekdek-api
```

### Monitoring Tools Needed

- Application: PM2
- Database: PostgreSQL built-in tools
- Web Server: Nginx access/error logs
- System: cron jobs for backups
- Optional: Prometheus, Grafana, ELK stack

---

## Disaster Recovery

### Backup Strategy

**Daily Database Backups**:
```bash
pg_dump tekdek_command_center | gzip > backup-$(date +%Y%m%d).sql.gz
```

**Recovery Time**: <5 minutes
**Backup Retention**: 30 days rolling

### Rollback Procedure

If critical issue found post-deployment:

```bash
1. Stop API: pm2 stop tekdek-api
2. Restore code: git revert HEAD
3. Restart: pm2 restart tekdek-api
4. If database corrupted: restore from backup
```

**Rollback Time**: ~10 minutes

---

## Post-Deployment Tasks

### Day 1
- Monitor logs every hour
- Test all features manually
- Verify backups are running
- Check performance metrics
- Gather team feedback

### Week 1
- Review error logs for patterns
- Monitor database growth
- Check disk space usage
- Verify SSL certificate renewal works
- Document any issues

### Monthly
