Drupal development agency; containerized client sites on VPS with CI/CD, monitoring, and backups

platforms with Ansible and Bash, and cutting 4 production client sites over with 5-10 minutes of downtime.

running automated PHP code checks in the CI stage and deploying to staging and production with automatic rollback
on failed releases.

• Edge and traffic: fronted client sites with Traefik and hardened Cloudflare with custom WAF and rate-limit rules,
blocking over half the bot traffic that previously reached origin.
