John Henry

I'm John Henry Donovan, an independent Craft CMS developer based in Cork, Ireland.

I help businesses, agencies, charities and publishers build websites that are fast, maintainable and built to last. Whether I'm joining an existing team or leading a project from the ground up, I focus on solving complex technical problems while keeping the editing experience simple for content teams.

Craft CMS has become my platform of choice because it gives organisations the flexibility to build exactly what they need without compromise. I specialise in custom Craft CMS and Craft Commerce development, bespoke plugins, API integrations, accessibility, performance optimisation and long-term support.

I'm also the creator of several open-source and commercial Craft CMS plugins used by developers and organisations around the world. Building plugins has given me a deep understanding of Craft's architecture and allows me to deliver robust, maintainable solutions that go beyond standard website development.

When you work with me, you're working directly with the developer writing the code. There are no layers of account managers or outsourced development—just practical advice, clear communication and carefully engineered solutions.

Whether you need a new Craft CMS website, a Commerce implementation, a custom plugin, help rescuing an existing project or ongoing technical support, I'd love to help.
