About

Built for the long run.

I specialize in building, maintaining, modernizing, and optimizing enterprise WordPress websites. My work centers on responsive front-end architecture, reusable components, WCAG-conscious implementation, Core Web Vitals, and content systems that remain understandable after launch.

My toolkit includes custom themes, Advanced Custom Fields, Timber and Twig, modern modular vanilla JavaScript bundled with Laravel Mix and Webpack, REST API integrations, multilingual WordPress, WooCommerce, and collaborative workflows across design, development, project management, and client teams—including AI-assisted development with ChatGTP Codex and Claude.
