Drupal development agency; containerized client sites on VPS with CI/CD, monitoring, and backups
• Maintenance and backups: applied scheduled OS, container, and network equipment updates, and backed up 6
projects incrementally to offsite storage with verification.
• Migrations: owned provider migrations for Drupal sites, benchmarking hosting options, provisioning replacement
platforms with Ansible and Bash, and cutting 4 production client sites over with 5-10 minutes of downtime.
• CI/CD: built and maintained pipelines (Bitbucket Pipelines, GitHub Actions, GitLab CI) for 5 client and internal projects,
running automated PHP code checks in the CI stage and deploying to staging and production with automatic rollback
on failed releases.
• Container environments: standardized a reusable Docker Compose baseline across 8 projects, 4-10 services per stack
(MariaDB, PHP, Nginx, Solr, Memcached), with per-project configuration for development, staging, and production.
• 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.

alert routing.
