Expert Drupal & Tech Articles

Practical articles and deep dives on Drupal development, AI, web accessibility, DevOps, and software quality from Metadrop's engineering team.

Engineering knowledge from real Drupal projects

Everything published here comes from production work: the contributed modules we maintain on drupal.org, the migrations, upgrades, and audits we deliver for enterprise clients, and the tooling we build to raise quality on every project. We document what we learn so your team can apply it.

  • DevOps and infrastructure — hosting, CI/CD, local environments, and platform migrations
  • Software quality — testing strategy, Behat, PHPUnit, and QA tooling
