+```
+
+---
+
+## 📋 Step-by-Step Deployment
+
+### 1. Prepare Server
+
+```bash
+# SSH to nexus-vector
+ssh admin@nexus-vector
+
+# Create deployment directory
+sudo mkdir -p /srv/containers/mtad-api
+cd /srv/containers/mtad-api
+
+# Clone repository
+git clone https://github.com/fullsizemalt/morethanadiagnosis-hub.git .
+cd backend
+
+# Copy production docker-compose
+cp docker-compose.prod.yml docker-compose.yml
+```
+
+### 2. Create SSL Certificates (Let's Encrypt)
+
+```bash
+# Install certbot
+sudo apt-get update
+sudo apt-get install -y certbot python3-certbot-nginx
+
+# Create certificate (interactive)
+sudo certbot certonly --standalone \
+  -d mtd.runfoo.run \
+  -d www.mtd.runfoo.run \
+  --agree-tos \
+  --email admin@morethanadiagnosis.com
+
+# Copy to nginx directory
+sudo mkdir -p /srv/containers/mtad-api/certbot/conf
+sudo cp -r /etc/letsencrypt /srv/containers/mtad-api/certbot/conf/
+
+# Fix permissions
+sudo chown -R admin:admin /srv/containers/mtad-api/certbot/
+```
+
+### 3. Configure Environment
+
+```bash
+# Copy .env template
+cp backend/.env.example backend/.env
+
+# Edit with production values
+nano backend/.env
+
+# Required values:
+# DB_PASSWORD=...
+# REDIS_PASSWORD=...
+# SECRET_KEY=...
+```
+
+### 4. Build and Start Services
+
+```bash
+# Build Docker image
+docker-compose build
+
+# Start all services
+docker-compose up -d
+
+# Wait for startup
+sleep 10
+
+# Check status
+docker-compose ps
+
+# Expected output:
+# NAME                  STATUS
+# mtad-postgres        Up (healthy)
+# mtad-redis           Up (healthy)
+# mtad-api             Up (healthy)
+# mtad-nginx           Up
+```
+
+### 5. Run Database Migrations
+
+```bash
+# Enter API container
+docker-compose exec api bash
+
+# Run migrations
+cd /app
+alembic upgrade head
+
+# Exit container
+exit
+```
+
+### 6. Verify Deployment
+
+```bash
+# Health check
+curl https://mtd.runfoo.run/health
+
+# Expected response:
+# {"status":"healthy","version":"v1","env":"production"}
+
+# API check
+curl https://mtd.runfoo.run/api/v1/health
+
+# Expected response:
+# {"status":"healthy","service":"MoreThanADiagnosis API"}
+
+# API docs
+curl https://mtd.runfoo.run/docs
+```
+
+### 7. Set Up Automatic Backups
+
+```bash
+# Create backup script
+cat > /srv/containers/mtad-api/backup.sh << 'EOF'
+#!/bin/bash
+BACKUP_DIR="/srv/containers/mtad-api/backups"
+TIMESTAMP=$(date +%Y%m%d_%H%M%S)
+
+mkdir -p $BACKUP_DIR
+
+# Backup database
+docker-compose exec -T postgres pg_dump -U admin morethanadiagnosis \
+  | gzip > $BACKUP_DIR/db_$TIMESTAMP.sql.gz
+
+# Keep only last 30 days
+find $BACKUP_DIR -name "db_*.sql.gz" -mtime +30 -delete
+
+echo "Backup completed: $BACKUP_DIR/db_$TIMESTAMP.sql.gz"
+EOF
+
+chmod +x /srv/containers/mtad-api/backup.sh
+
+# Schedule daily backups (crontab)
+# Edit: crontab -e
+# Add: 0 2 * * * /srv/containers/mtad-api/backup.sh >> /var/log/mtad-backup.log 2>&1
+```
+
+---
+
+## 🔍 Monitoring & Maintenance
+
+### Health Checks
+
+```bash
+# System health
+curl https://mtd.runfoo.run/health
+
+# API health
+curl https://mtd.runfoo.run/api/v1/health
+
+# Readiness check
+curl https://mtd.runfoo.run/api/v1/ready
+```
+
+### Logs
+
+```bash
+# Real-time logs
+docker-compose logs -f
+
+# Specific service
+docker-compose logs -f api
+docker-compose logs -f postgres
+docker-compose logs -f redis
+
+# Last 100 lines
+docker-compose logs --tail=100
+```
+
+### Resource Usage
+
+```bash
+# CPU and memory
+docker stats
+
+# Disk usage
+df -h /srv/containers/mtad-api
+
+# Database size
+docker-compose exec postgres psql -U admin -d morethanadiagnosis -c \
+  "SELECT pg_size_pretty(pg_database_size('morethanadiagnosis'));"
+```
+
+### Restart Services
+
+```bash
+# Restart single service
+docker-compose restart api
+
+# Restart all
+docker-compose restart
+
+# Stop services
+docker-compose stop
+
+# Start services
+docker-compose start
+
+# Full restart
+docker-compose down && docker-compose up -d
+```
+
+---
+
+## 🔄 SSL Certificate Renewal
+
+Let's Encrypt certificates expire every 90 days. Set up automatic renewal:
+
+```bash
+# Test renewal
+sudo certbot renew --dry-run
+
+# Set up automatic renewal (cron)
+# Edit: sudo crontab -e
+# Add: 0 3 * * * certbot renew --quiet && docker-compose reload -s nginx
+```
+
+---
+
+## 📊 Performance Tuning
+
+### Database Optimization
+
+```bash
+# Connect to database
+docker-compose exec postgres psql -U admin -d morethanadiagnosis
+
+# Check index usage
+SELECT * FROM pg_stat_user_indexes;
+
+# Check table sizes
+SELECT schemaname, tablename, pg_size_pretty(pg_total_relation_size(tablename))
+FROM pg_tables
+ORDER BY pg_total_relation_size(tablename) DESC;
+
+# Vacuum and analyze
+VACUUM ANALYZE;
+```
+
+### Redis Cache
+
+```bash
+# Check memory usage
+docker-compose exec redis redis-cli INFO memory
+
+# Clear cache (if needed)
+docker-compose exec redis redis-cli FLUSHALL
+```
+
+### Nginx Performance
+
+```bash
+# Check worker processes
+ps aux | grep nginx
+
+# Monitor connections
+netstat -an | grep ESTABLISHED | wc -l
+```
+
+---
+
+## 🆘 Troubleshooting
+
+### API Not Responding
+
+```bash
+# Check if containers are running
+docker-compose ps
+
+# Check logs
+docker-compose logs api
+
+# Restart API
+docker-compose restart api
+
+# Check connectivity
+curl -v https://mtd.runfoo.run/health
+```
+
+### Database Connection Errors
+
+```bash
+# Check postgres status
+docker-compose logs postgres
+
+# Test database connection
+docker-compose exec postgres psql -U admin -d morethanadiagnosis -c "SELECT 1"
+
+# Check disk space
+df -h
+
+# Restart postgres (WARNING: will interrupt connections)
+docker-compose restart postgres
+```
+
+### High Memory Usage
+
+```bash
+# Check which service
+docker stats
+
+# Redis memory
+docker-compose exec redis redis-cli INFO memory
+
+# Clear Redis cache (temporary)
+docker-compose exec redis redis-cli FLUSHALL
+
+# Permanent: update docker-compose.yml maxmemory-policy
+```
+
+### Certificate Issues
+
+```bash
+# Check certificate
+sudo openssl x509 -in /etc/letsencrypt/live/mtd.runfoo.run/fullchain.pem -text
+
+# Renew certificate
+sudo certbot renew --force-renewal
+
+# Restart nginx
+docker-compose restart nginx
+```
+
+---
+
+## 🔒 Security Best Practices
+
+### Firewall
+
+```bash
+# Allow only necessary ports
+sudo ufw allow 22/tcp    # SSH
+sudo ufw allow 80/tcp    # HTTP
+sudo ufw allow 443/tcp   # HTTPS
+sudo ufw allow 8080/tcp  # Health check
+sudo ufw enable
+```
+
+### Regular Updates
+
+```bash
+# Update base images monthly
+docker pull postgres:15-alpine
+docker pull redis:7-alpine
+docker pull nginx:alpine
+
+# Rebuild and restart
+docker-compose build
+docker-compose up -d
+```
+
+### Access Control
+
+```bash
+# Restrict file permissions
+chmod 600 /srv/containers/mtad-api/.env
+chmod 600 /srv/containers/mtad-api/certbot/conf/letsencrypt/*/privkey.pem
+
+# Restrict directory
+chmod 750 /srv/containers/mtad-api
+```
+
+---
+
+## 📈 Scaling & Load Balancing
+
+### Horizontal Scaling
+
+For multiple API instances:
+
+```yaml
+# In docker-compose.yml
+services:
+  api:
+    deploy:
+      replicas: 3
+
+  # Nginx will load balance automatically
+```
+
+### Database Replication
+
+For high availability:
+- Set up PostgreSQL primary-replica replication
+- Use read replicas for analytics
+- Configure automatic failover
+
+---
+
+## 🔄 CI/CD Integration
+
+### GitHub Actions for Auto-Deploy
+
+```yaml
+name: Deploy to Production
+
+on:
+  push:
+    branches: [main]
+    paths:
+      - 'backend/**'
+
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v3
+      - name: Deploy to nexus-vector
+        run: |
+          ssh admin@nexus-vector "cd /srv/containers/mtad-api && \
+            git pull origin main && \
+            docker-compose build && \
+            docker-compose up -d"
+```
+
+---
+
+## 📊 Monitoring Setup (Optional)
+
+### With Prometheus & Grafana
+
+```bash
+# Add to docker-compose.yml for monitoring
+prometheus:
+  image: prom/prometheus
+  volumes:
+    - ./prometheus.yml:/etc/prometheus/prometheus.yml
+  ports:
+    - "9090:9090"
+
+grafana:
+  image: grafana/grafana
+  ports:
+    - "3000:3000"
+```
+
+### Sentry for Error Tracking
+
+Update backend config to send errors to Sentry:
+
+```python
+import sentry_sdk
+sentry_sdk.init(dsn="https://YOUR_KEY@sentry.io/PROJECT_ID")
+```
