Drupal development — architecture, contributed modules, upgrades, migrations, and performance
AI and automation — practical AI integrations in Drupal, LLM tooling, and editorial workflows
Web accessibility — WCAG compliance and the European Accessibility Act
DevOps and infrastructure — hosting, CI/CD, local environments, and platform migrations
Software quality — testing strategy, Behat, PHPUnit, and QA tooling
