Joe Hahn

Senior Drupal & web developer. 20+ years building, migrating, and maintaining sites for universities, nonprofits, and businesses.

Drupal is my specialty — I've carried sites through every major version from Drupal 6 to 11, built custom themes and editorial workflows, and rescued more than one inherited or failing codebase. A lot of my best work is the untangling kind: stepping into an existing site, figuring out how it's actually put together, fixing what's broken, and making changes safely without breaking what already works.

Available for part-time, remote, and contract work.

What I do

  • Drupal & WordPress — builds, redesigns, upgrades, long-haul migrations, and ongoing support
  • Analytics & tag management — GA4 migrations, Google Tag Manager from scratch, Consent Mode v2
  • CRM & fundraising — Salesforce (certified Admin, Platform Developer I, JavaScript Developer I), Marketo, GiveCampus, Blackbaud Luminate
  • Email — hand-coded, bulletproof responsive HTML templates
  • Accessibility — WCAG 2.1 AA audits and remediation

How I work

Every repo above ships with a license, CI and a tagged release. Drupal code runs through drupal-module-ci (phpcs Drupal + DrupalPractice, phpstan with deprecation rules, PHPUnit) on every push, and the drupal-claude-skills repo is how I keep AI-assisted work to the same standard.
