About

Plugin author on WordPress.org, active on GitHub, and recent platform work includes NYProSe (New York Supreme Court divorce workflows).

Typical projects: site rebuilds, custom plugins, WooCommerce and Shopify storefront work, Squarespace or Joomla to WordPress migrations, Core Web Vitals tuning, and guardrailed AI publishing (Sheets, n8n, REST). Work runs in Git with staging URLs before production and milestones your PM can track.
